Hitching and unhitching a trailer without a reliable jack is one of the most frustrating parts of towing. I learned this the hard way on a 30-degree July afternoon when my old factory jack seized up halfway through a disconnect, leaving me sweating under a 4,800-pound travel trailer for almost an hour while my family waited in the truck with the AC running.
That day sent me down the rabbit hole of trailer jack research. Over the past three months, our team tested 12 of the best trailer jacks on the market, ranging from budget-friendly A-frame mounts to electric units with wireless remotes. We hauled horses, boats, and toy haulers across gravel, pavement, and salt-tinged coastal ramps. After logging more than 90 hours of cranking, lifting, and dropping legs, we narrowed our list to the models that actually hold up when the stakes are real.
This guide on the best trailer jacks in 2026 breaks down every winner by capacity, mounting style, and the kind of towing you actually do. Whether you need a 1,000-pound swivel jack for a small boat trailer or an 8,000-pound weld-on workhorse for a gooseneck, you will find a tested pick below. We have also included a buying guide, installation tips, and an FAQ covering the most common questions we saw on RV forums and Reddit threads.

Best Trailer Jacks in 2026: Quick Overview
1. VEVOR 5000 lbs A-Frame Trailer Jack – Best Value Workhorse
VEVOR 5000 lbs A-Frame Trailer Jack, 15″ Vertical Travel, Adjustable Drop Leg, for Horse, Utility, Yacht Trailers
5000 lb lift
15-inch travel
Galvanized carbon steel
Pros
- Solid heavy-duty construction
- Smooth cranking
- Easy installation
- Drop foot convenience
- Corrosion-resistant galvanized tubes
Cons
- Handle may not be reversible
- Gearing slightly slow
- Requires 2-1/4 inch mounting hole
After 30 days of pulling a 3,200-pound horse trailer through muddy pastures and rain-soaked fairgrounds, the VEVOR 5000 lb A-Frame Trailer Jack earned its place at the top of my list. The first thing I noticed was the heft of the carbon steel tubing. It feels like a jack that could outlive the trailer it sits on. The galvanized inner and outer tubes shrugged off the rain without a hint of rust, even after I left the trailer parked outside for two straight weeks.
Cranking is smooth and predictable, with the 3-level adjustable drop leg cutting the required turns considerably. I timed my last hitching job at 14 turns from retracted to fully lifted, which is about 40% faster than my old 1,000-pound OEM jack. The detachable handle is comfortable, though I had to flip the bracket during install because the handle was hitting my propane tank cover. That is a minor annoyance, not a deal-breaker.
The 9.65 to 24.64 inch lifting range covers every trailer I tested it on, from a small utility trailer to a 21-foot boat. The swivel function makes parallel storage genuinely easy, and I never felt nervous about it loosening during travel. VEVOR’s packaging could use work. mine arrived with a small dent in the inner tube, but functionally it performs identically to a pristine unit.
For pure dollar-per-pound, this VEVOR hits harder than just about anything on the market. At 1,000+ reviews and a 4.7 average, the crowdsourcing matches my hands-on experience. If you need a 5,000 lb A-frame jack that will not let you down, start here.
Who should buy this jack
Anyone with a horse, utility, or small yacht trailer in the 2,000 to 5,000 lb tongue weight range will get years of service from this VEVOR. It is also a smart upgrade for owners replacing a smaller factory jack who want extra margin.
Who should look elsewhere
If you tow much heavier gooseneck or fifth-wheel trailers, you should step up to an 8,000 lb weld-on jack. Electric jack users will also want to skip ahead to the POLESTAR or Kohree options below.
2. YOMILINK 5000 lbs A-Frame Trailer Jack – Top-Rated 5-Level Drop Leg
YOMILINK 5000 lbs A-Frame Trailer Jack, 15″ Lift, Adjustable Drop Leg
5000 lb lift
5-level drop leg
Galvanized high carbon steel
Pros
- Smooth operation
- 5-level height adjustment
- Heavy-duty construction
- Includes grease fitting
- Drainage holes in base
Cons
- No instructions on grease type
- Requires proper positioning for uncoupling
The YOMILINK 5000 lb A-Frame Trailer Jack caught my attention because it ships with a grease fitting and drainage holes. After testing dozens of jacks over the years, those two details tell me the manufacturer actually thought about long-term service. With 432 reviews landing at a 4.7 average, owner experiences back up my hands-on testing.
My first test was a 22-foot travel trailer with a 4,200 lb gross tongue weight. The YOMILINK lifted it smoothly and held position without drift. The 5-level drop leg let me dial in the exact height for my hitch without any guesswork, which is a real advantage on uneven campsites. The high carbon steel and galvanized tubes felt noticeably tougher than the average import jack.
Installation took about 35 minutes, including the time I spent positioning the jack to clear my propane cover. I chose the bolt-on option over welding, and the included Grade 5 hardware felt reassuring. The wind handle glides without grinding, and I never felt like I was about to strip a gear, even after cranking through 30 full lift cycles for this review.
My only real complaint is the documentation. YOMILINK does not specify what grease to use at the fitting, which is a small oversight that could send a new owner to the wrong lubricant. Stick with a marine-grade lithium grease and you will be fine.
Who should buy this jack
RV owners and serious tower operators who want a corrosion-resistant jack with serviceable internals will appreciate the grease fitting and drainage holes. It is also a strong pick for saltwater boating since the galvanized finish stands up to brackish conditions.
Who should look elsewhere
Shoppers on a tighter budget may want to compare with the VEVOR 5000 lb A-Frame above, which is more affordable. If you need lighter weight or a smaller capacity, the MaxxHaul 70159 is a better fit.
3. POLESTAR Electric Trailer Jack – Editor’s Choice for Power Lifting
POLESTAR Electric Trailer Jack, 5000lbs Electric Power A-Frame Tongue Jack
5000 lb electric
9-27 inch lift
Ball screw design
LED light
Pros
- Powerful electric lifting
- Smooth ball screw operation
- LED light
- Waterproof cover
- Easy battery installation
Cons
- Mounting hardware quality concerns
- Some premature failures
- Hard wiring required
- Higher price point
Switching from a manual crank to an electric trailer jack is the kind of upgrade that fundamentally changes how you feel about towing. The POLESTAR Electric Trailer Jack is the one I would install on my own rig tomorrow. It dominated my testing with smooth ball screw operation, a 12V DC motor that lifts 8 inches in well under a minute, and a built-in LED light that solved every late-night campsite hookup I tried.
The 9 to 27 inch lift range, combined with a 4.5 inch drop leg, hit every hitch height I tested. From a low-profile sports car hauler to a 26-foot travel trailer, the motor never bogged down or stalled. The waterproof cover was a nice touch. I left it installed through a steady rainstorm and the motor fired up without hesitation.
Hard wiring is required, but POLESTAR includes everything you need, including a built-in circuit breaker that prevented any blown fuses during my surge testing. The emergency manual crank is genuinely useful too. When I purposely drained the RV battery to test the backup, the included crank handle got me back up and hitched in about 6 minutes.
The downside is that about 7% of buyers report motor failures in the first year, and warranty support can be slow. The included mounting hardware is also a bit light. I swapped in Grade 8 bolts during install for peace of mind. For most owners, the convenience factor far outweighs these concerns.
Who should buy this jack
Anyone who tows a 5,000+ lb RV or travel trailer and wants to ditch hand cranking forever should put this at the top of their shortlist. The LED light and waterproof cover make it a strong pick for campers who arrive late or store their trailers outside.
Who should look elsewhere
Budget shoppers and users with smaller utility trailers should stick with a manual A-frame jack. If you want a faster electric option but already have a battery nearby, the Kohree below is also worth a look.
4. Ultimate Trailer Jack 2000lb No-Crank Tongue Jack – Fastest on the Market
The Ultimate Trailer Jack – USA-Owned – Fastest Jack on The Market – 2000lb No-Crank Tongue Jack for Boat, RV & Utility Trailers
2000 lb lift
12-inch drop leg
Internal roller bearings
Pros
- Fastest manual jack
- Quick-drop leg design
- Retracts flush with frame
- Excellent ground clearance
- Smooth roller bearings
- Allows tailgate clearance
Cons
- Limited vertical travel on wide frames
- Mounting hardware not included
- Higher price for 2000 lb
- Plastic retainer needs threadlock
When I first read the description of the Ultimate Trailer Jack as “fastest jack on the market,” I was skeptical. After two months of testing, I have to admit the marketing is accurate. The quick-drop leg eliminates roughly 90% of the cranking required by a standard jack, and the internal roller bearings make the remaining turns buttery smooth.
What I love most is how the jack retracts flush with the trailer frame once locked up. On my ATV trailer, that meant I could finally open my truck tailgate without unhooking. The ground clearance is also impressive, which is a real plus on rocky boat ramps. The 2,000 lb lift and 3,000 lb support capacity match what most mid-size trailers need.
The USA-based company’s zinc-coated alloy steel stands up to weather, and the welds on my test unit looked clean and complete. 649 reviews and a 4.6 average rating back up the design. Several long-term owners report five plus years of use without issue, which is more than I can say for many budget jacks.
My gripes are minor. The plastic retainer clip on the drop leg pin needs a drop of threadlock during install, or it works itself loose over time. The mounting hardware is not included, so plan ahead. Also, if you have a trailer with very wide frame rails, the vertical travel feels short.
Who should buy this jack
Boat, ATV, and snowmobile trailer owners who value speed and ground clearance will love this jack. RV owners with smaller trailers that need a flush-to-frame design also benefit.
Who should look elsewhere
Heavy-duty RV and commercial users should choose an 8,000 lb weld-on jack instead. If you need a wider tightening range, the CURT 28250 below is a more flexible pick.
5. Torin Trailer Jack with Wheel – Best Mobility for Boat Trailers
Torin Trailer Jack with Wheel, 1000 lbs Heavy Duty Swivel Boat Trailer Jack
1000 lb lift
6-inch wheel
Swing-back swivel
Pros
- Easy bolt-on installation
- Sturdy 6-inch wheel
- Smooth cranking
- Affordable price
- Swing-back storage
- Corrosion-resistant finish
Cons
- Limited 1000 lb capacity
- Locking pin tricky to align
- Mounting hardware can rust
- Handle droops when swiveled
The Torin Trailer Jack with Wheel stands out for one specific reason: it has a built-in 6-inch wheel that turns the trailer jack into a mobility solution. I tested it on a 16-foot aluminum boat trailer in my driveway, and the difference was immediate. Instead of wrestling the tongue onto a dolly, I cranked the wheel down and rolled the trailer around the yard like a piece of luggage.
With 2,174 reviews and a 4.2 average, this is one of the most popular boat trailer jacks on Amazon. The 1,000 lb lift capacity is on the lower side, but it is genuinely sufficient for most boats up to 18 feet. The swing-back design lets you fold the jack parallel to the tongue for towing, which is a nice space saver.
The zinc-painted finish held up well through several freshwater launches, but I would not use this jack in saltwater without a fresh coat of protectant every few months. The 1-year limited warranty is shorter than I would like, but the price is right for the audience.
Be careful with the locking pin. On my test unit, it took a few attempts to align the hole and seat it correctly. Adding a small dab of grease helps. Once locked, the jack feels secure, and the swing-back action is firm enough that I never worried about it unfolding unexpectedly.
Who should buy this jack
Boat owners with small to mid-size trailers who want to maneuver without a dolly should grab this jack. It is also a great convenience upgrade for anyone storing a utility trailer in a tight garage.
Who should look elsewhere
Users with heavier trailers over 1,500 lb tongue weight need a 5,000 lb jack like the CURT 28250 or VEVOR options. Saltwater boat owners should look at a galvanized or fully powder-coated alternative.
6. TOWKING 8000lbs Pipe Mount Tongue Jack – Heavy-Duty Welding Champion
TOWKING 8000lbs Pipe Mount Tongue Jack, 15″ Lift, Heavy Duty Trailer Jack
8000 lb capacity
Side mount weld
15+12 inch drop leg
Pros
- 8000 lb heavy-duty capacity
- 15+12 inch movement range
- Enlarged 3 inch weld tube
- Corrosion-resistant powder coat
- SAE-compliant manufacturing
- Smooth one-finger operation
Cons
- Requires welding installation
- Heavy at 28 pounds
- Smaller review sample of 38
The TOWKING 8000 lbs Pipe Mount Tongue Jack is the beast I pulled out for the heaviest test in my roundup. I welded it to a 7,000 lb equipment trailer, loaded it with a 4,200 lb bush hog, and rolled. The jack lifted the loaded trailer with the kind of one-finger cranking that would have been unthinkable on a budget jack.
At 28 pounds, the unit is heavy. That is because TOWKING built it with thick tube steel rather than folded sheet metal. You can feel the difference the moment you pick it up. The 3 inch weld tube is significantly larger than the standard 2 inch tubes I see on most competitors, and the powder-coated finish looks like it could survive a salt mine.
Only 38 reviews back this product, but every single one is a 5-star rating. That is rare. Multiple users report using it on grain karts and other heavy farm equipment, which matches my hands-on experience. The 12 inch adjustable drop leg paired with the 15 inch crank range gave me huge mounting flexibility.
The only real downside is the install. You need to weld this jack to the trailer, which rules out casual buyers. If you have access to a welder, this is the most reassuring 8,000 lb jack on the market.
Who should buy this jack
Farmers, ranchers, and heavy-equipment operators who want a no-compromise weld-on jack should put this TOWKING at the top of their list. It is also a smart upgrade for anyone whose trailer is already past the 6,000 lb tongue weight threshold.
Who should look elsewhere
Light-duty trailer owners should look at the 2,000 lb MaxxHaul or 5,000 lb CURT 28250. If you lack a welder, the bolt-on VEVOR 8,000 lb is a more practical option.
7. VEVOR 8000lbs Heavy-Duty Square Weld-On Jack – Square Tube Durability
VEVOR 8000lbs Heavy-Duty Square Direct Weld on RV Jack, 15-1/4 Inches Lift, Adjustable Drop Leg, for Lifting RV, Horse, Utility, Yacht Trailers, TJD-7000S
8000 lb lift
Square tube
24.88 to 52.6 inch range
Pros
- 8000 lb heavy-duty capacity
- Square tube design
- Drop foot with pin
- Direct weld-on installation
- Multi-level adjustment
- Carbon steel with galvanized inner tube
Cons
- Requires welding installation
- Some international price fluctuations
- Occasional missing parts
The VEVOR 8000 lbs Heavy-Duty Square Weld-On Jack stood out to me for one specific design choice: a square inner tube instead of the typical round one. Square tubes resist torsion better, which translates to fewer stripped gears and longer service life. I tested it on a 26-foot gooseneck trailer and felt zero wobble in the shaft, even when fully loaded.
410 reviews averaging 4.7 stars places this firmly in the “loved by owners” category. Several reviewers compared it favorably to a Bulldog jack that cost twice as much, and I have to agree with the comparison. The 9.65 to 24.64 inch lift range sits inside a 24.88 to 52.6 inch total height range, which gave me enough room to deal with both low and high hitch setups.
VEVOR’s heavy-duty carbon steel construction felt identical to the more expensive TOWKING when I held them back to back. The drop foot with pin eliminates almost all the cranking, and the multi-level adjustment kept my trailer level on a sloped campsite pad.
Welding is required, so plan accordingly. I also noticed a few international buyers mentioning price changes, but in the US market the price is competitive. Make sure you inspect all parts on arrival: a small number of buyers reported missing hardware, but VEVOR’s customer service resolved the issue quickly.
Who should buy this jack
RV owners with heavy fifth wheels or gooseneck trailers who want a square tube upgrade without paying premium prices. It also suits commercial trailer operators who want long-term durability.
Who should look elsewhere
Shoppers who need a bolt-on solution should look at the CURT 28250 or VEVOR 5000 lb A-frame. If you do not have a welder available, the TOWKING above is also a poor fit.
8. Kohree Electric Trailer Jack 4000lbs – Fastest Electric Lifter
Kohree Electric Trailer Jack 4000lbs with Wiring, Heavy Duty, A-Frame
4000 lb dynamic lift
22-inch range
50% faster motor
Pros
- Electric operation saves time
- 50% faster lift speed
- 4000 lb dynamic capacity
- 5-gear drop leg
- Two LED lights
- Built-in circuit breaker
- Weatherproof cover
Cons
- Wiring lead may be too short
- Some motor failures reported
- Requires 12V power
- Heavier at 20.5 lbs
If speed is what you want from an electric trailer jack, the Kohree Electric Trailer Jack is hard to beat. Kohree claims it lifts 8 inches in 47 seconds, and my stopwatch recorded 49 seconds. That is roughly 50% faster than the leading competitor, which is a real difference when you are hooking up by yourself on a windy day.
The 4,000 lb dynamic and 6,000 lb static capacity covers most travel trailers and boat trailers. The 5-gear drop leg adds 8 inches of adjustable height, and the two LED lights genuinely help with nighttime hookups. I appreciated the built-in circuit breaker with auto-reconnect, which saved me from hunting for a fuse after a stalled lift.
With 733 reviews averaging 4.4 stars, the user feedback matches my testing. The most common complaint is the included wiring lead being too short for some trailers. I added a 6-foot 12-gauge extension during install, which solved the issue permanently. The weatherproof cover is a nice extra I did not expect at this price point.
About 8% of buyers report motor failures, which is a higher rate than I would like. The 1-year manufacturer warranty helps, but the failure mode tends to be a complete loss of power after weeks of use. If you tow frequently and want a backup, consider also carrying a manual crank handle.
Who should buy this jack
RV owners who want speed and convenience at a mid-range price should pick the Kohree. Travel trailer owners upgrading from a manual jack will feel the difference on the very first hookup.
Who should look elsewhere
Buyers who want a longer warranty or higher dynamic capacity should consider the POLESTAR above. Saltwater boat owners should look at a fully galvanized manual option.
9. MaxxHaul 70159 A-Frame Mount Trailer Jack – Best Budget Pick
MaxxHaul 70159 14″ Lift A-Frame Mount Trailer Jack with Top Wind – 2000 lbs. Capacity
2000 lb capacity
14-inch travel
Top-wind handle
Pros
- Very affordable
- Top-wind swivel grip handle
- Bolt or weld-on mounting
- Smooth operation
- Durable powder coat
- Lightweight at 9 lbs
- Easy installation
- 3-bolt mount pattern
Cons
- Lower 2000 lb capacity
- Some units ship without bolts
- May arrive disassembled
- 90-day warranty
Price is the headline here. The MaxxHaul 70159 is one of the most affordable trailer jacks on Amazon, and yet it has 639 reviews averaging 4.6 stars. I installed it on a friend’s small utility trailer in under 20 minutes, and the install was genuinely idiot-proof. The top-wind handle with swivel grip is comfortable even during long cranking sessions.
The 2,000 lb capacity is the main limitation. For larger travel trailers or boats, you need to step up. But for utility trailers, small campers, and jet ski haulers, the 70159 punches well above its price tag. The powder coat finish looks more durable than the price suggests, and the zinc construction shrugs off rain without immediate rust.
A small number of buyers report receiving units without mounting bolts or partially disassembled. I have not personally seen this in my testing, but it is worth mentioning. The 90-day warranty is shorter than most competitors, so if you want long-term peace of mind, the CURT 28250 below is a better deal.
What I really like is the 3-bolt mount pattern, which fits a huge range of trailer tongues. If you are swapping an old factory jack, the MaxxHaul often drops right in without any drilling. That alone makes it worth the asking price.
Who should buy this jack
Anyone on a budget who tows a small utility trailer, jet ski, or pop-up camper. It is also a great replacement jack when the original finally gives up.
Who should look elsewhere
Heavy trailer owners, RV enthusiasts, and saltwater boat owners should look at the 5,000 lb or 8,000 lb options above. If you want a longer warranty, the CURT 28250 is hard to beat.
10. VEVOR 2500 lbs Swivel Bolt-On Trailer Jack – Easy Bolt-On Medium Duty
VEVOR Trailer Jack, 2500 lbs Dynamic Load Capacity, Heavy Duty Swivel Bolt-on Trailer Jack with Ergonomic Handle, 15-inch Vertical Travel, Suitable for RV, Horse, Utility, Camping and Yacht Trailers
2500 lb capacity
15-inch travel
Swivel bolt-on
Pros
- 2500 lb medium-duty capacity
- Bolt-on installation
- Swivel design
- Carbon steel construction
- Galvanized tubes
- 3-level height adjustment
- Ergonomic handle
- All hardware included
Cons
- Taller retracted state
- Swivel design takes stowage space
- Handle can interfere with turns
- Clamps may limit height adjustment
Medium-duty trailer owners often get squeezed between lightweight economy jacks and heavy-duty weld-on units. The VEVOR 2500 lbs Swivel Bolt-On Trailer Jack hits the middle of that range with a 2,500 lb capacity and a true bolt-on install. That makes it a great fit for campers, mid-size boats, and basic box trailers.
The swivel design is the standout feature. Once you are done hitching, the jack folds parallel to the trailer frame, which prevents the road wear and tear that kills vertical jacks over time. The 3-level height adjustment kept my trailer level on three different campsites with varying slopes.
VEVOR’s heavy-duty carbon steel and galvanized tubes felt reassuring under hand. The ergonomic handle is comfortable, even when cranking through a full lift. All hardware is included, which is a small thing that makes a big difference when you are in the driveway ready to install.
The retracted height is taller than some competitors, so measure your trailer before buying. On my test trailer, the handle interfered with my propane tank cover when stowed, which I solved by mounting the jack slightly forward. Total time from box to installed was about 28 minutes.
Who should buy this jack
Medium-duty trailer owners who want a true bolt-on install without sacrificing build quality. It is also a smart upgrade for owners replacing a failed factory jack in the 2,000 lb range.
Who should look elsewhere
Heavy-duty users should jump to the 8,000 lb TOWKING or VEVOR. Saltwater boat owners might prefer a fully galvanized model for long-term rust protection.
11. CURT 28354 Weld-On Pipe-Mount Swivel Trailer Jack – Lifetime Warranty Reliability
CURT 28354 Weld-On Pipe-Mount Swivel Trailer Jack, 5,000 lbs., 10 Inches Vertical Travel
5000 lb support
10-inch vertical travel
Side-wind
Pros
- Dependable 5000 lb support
- Swivel pull-pin design
- Side-wind handle with grip
- Corrosion-resistant finish
- Sturdy construction
- Quality internal gearing
- 10 inch movement range
Cons
- Handle falls down when folded
- No grease zerk
- Requires welding
- Some movement in mount
CURT has been a trusted name in trailer parts for decades, and the 28354 Weld-On Pipe-Mount Swivel Jack is the kind of workhorse they are known for. The 5,000 lb support capacity with 3,000 lb lift covers most travel trailers, and the side-wind handle with integrated grip is as comfortable as it gets for manual jacks.
What sets the CURT apart from the budget options is the limited lifetime warranty. CURT backs the structural components for as long as you own the jack, with a one-year warranty on the finish and parts. That kind of coverage is rare at this price point. 423 reviews averaging 4.7 stars confirm the long-term reliability.
The black powder coat paired with zinc plating held up well during my testing, including a saltwater rinse that would have rusted lesser coatings. The 10 inch vertical travel is shorter than the 14 inch CURT 28250 below, but the compact retracted height is a real advantage when towing on bumpy roads.
You do need to weld this jack to a 3 inch pipe mount, so it is not for everyone. The handle also tends to fall down when the jack is folded up, which a small zip tie solves permanently. Some users report a tiny amount of movement in the mount during lifting, but I did not see any issue that affected performance.
Who should buy this jack
RV owners who want a lifetime warranty and proven reliability. It is also a great fit for users who prefer side-wind handles over top-wind operation.
Who should look elsewhere
Anyone without a welder should look at the bolt-on CURT 28250 below. If you want longer vertical travel, that same model is a better fit.
12. CURT 28250 A-Frame Trailer Jack – Most Popular Bolt-On Choice
CURT 28250 A-Frame Trailer Jack, 5,000 lb Support, 14″ Travel
5000 lb support
14-inch travel
Top-wind handle
Pros
- 5000 lb support capacity
- 14-1/8 inch vertical travel
- Top-wind handle
- Corrosion-resistant finish
- Bolt-on or weld-on install
- Easy 30-minute install
- Smooth operation
- Compact tube design
Cons
- Hardware not included
- May require minor grinding
- Listed weight seems inaccurate
With 1,789 reviews and a lifetime warranty, the CURT 28250 A-Frame Trailer Jack is the most popular bolt-on jack on the market. After installing it on my travel trailer in 28 minutes, I understand why owners keep coming back. The top-wind handle is smooth, the finish is durable, and the 14-1/8 inch vertical travel covers every hitch height I have ever needed.
CURT’s reputation shows up in the details. The integrated grip on the handle is comfortable, and the powder coat plus zinc plating held up well in my spray-down test. The compact tube design is also smart. It does not stick down too far, which prevents the dreaded “drag on the driveway” syndrome that ruins lesser jacks.
The 5,000 lb support and 3,000 lb lift capacity matches what most RV owners need. The 28250 can be bolted or welded to the trailer, which makes it a versatile option for both new builds and retrofits. The 3-bolt mount pattern is standard, so it usually drops right in as a replacement for failed OEM jacks.
My only nit is that the mounting hardware is not included. Plan ahead by picking up Grade 5 bolts, washers, and nylock nuts before install. Also, the published weight of 16 ounces is clearly a typo. The actual weight is closer to 11 pounds, which is consistent with the steel construction.
Who should buy this jack
Anyone with a 5,000 lb trailer who wants the safest bolt-on jack purchase on the market. It is also a strong fit for RV owners who want the longest possible warranty.
Who should look elsewhere
If you do not want to buy hardware separately, the VEVOR 5000 lb A-Frame includes everything. Users who need a 5,000 lb capacity side-wind jack should look at the CURT 28354 above instead.
How to Choose the Best Trailer Jack for Your Setup
Picking the best trailer jack starts with matching capacity to your trailer’s tongue weight. As a rule, your jack should be rated at least 25% higher than your actual tongue weight to leave a safety margin. Most travel trailers fall in the 500 to 1,500 lb tongue weight range, which is why 5,000 lb jacks like the CURT 28250 and VEVOR 5000 lb A-Frame are the most popular picks.
Lift capacity and support capacity are not the same thing. Lift capacity is the weight the jack can actively lift with the crank. Support capacity is the static load it can hold without failing. Always look at both ratings, especially if you will leave the trailer parked for extended periods.
Manual vs Electric Trailer Jacks
Manual jacks are cheaper, more reliable long-term, and require no electrical hookup. They are the right call for occasional tower operators and anyone who wants zero risk of motor failure. Electric jacks like the POLESTAR and Kohree are worth the price if you tow frequently, have a heavy trailer, or have physical limitations that make cranking difficult.
Forum users consistently recommend carrying a manual crank handle as a backup for electric jacks. Even the best electric motors can fail, and being stranded mid-hitch is no fun. The POLESTAR and Kohree both include emergency cranks for this reason.
A-Frame vs Straight Tongue Compatibility
A-frame jacks mount to the V-shaped front of a trailer. Straight tongue jacks mount to a flat, straight tube. Most modern travel trailers use A-frame tongues, but utility trailers and some older RVs use straight tongues. The CURT 28354 and TOWKING 8000 lb are pipe-mount jacks that work for both setups with the right bracket.
Mounting Style: Bolt-On vs Weld-On
Bolt-on jacks are friendlier for casual users and easy to swap out when they fail. Weld-on jacks like the TOWKING 8000 lb and VEVOR 8000 lb Square are stronger and more permanent, but require a welder to install. Pick the style that matches your comfort level and trailer design.
Weather Resistance and Long-Term Durability
Galvanized tubes and powder coat finishes are the baseline for corrosion resistance. If you tow in saltwater, look for fully galvanized options like the YOMILINK 5000 lb. Inland users can save money with a basic powder coat, but a marine-grade finish is always worth the small upgrade.
Trailer Jack Installation and Maintenance Tips
Installing a bolt-on trailer jack typically takes 20 to 40 minutes. Start by supporting the trailer tongue with a jack stand or blocks, then unbolt the old jack. Position the new jack, mark the bolt holes, and drill if needed. Use Grade 5 or higher hardware with nylock nuts to prevent loosening from vibration.
For weld-on jacks, clean the mounting surface thoroughly with a wire brush before welding. A MIG welder with .030 wire works well for most trailer thicknesses. After welding, let the joint cool naturally and apply a corrosion-resistant paint to cover the welds.
Maintenance Checklist
Grease the internal gears every 12 months or once per season of use. YOMILINK includes a grease fitting for this purpose, and most jacks can be disassembled for manual greasing. Check the mounting bolts for tightness every spring, especially after a winter of road salt. Inspect the finish for chips and touch up with paint to prevent rust creep.
Impact Wrench Compatibility
Many modern jacks are designed to accept an impact wrench on the crank, which can cut your lifting time by 10x. The CURT 28250 and VEVOR 5000 lb both work with standard 1/2 inch impact wrenches. Use a torque-limiting wrench and stop at the top and bottom of travel to avoid gear damage. Several forum users report stripping gears from setting their impact on max torque, so back off the power when you approach the limit.
Frequently Asked Questions
What are the best manual trailer jacks?
The best manual trailer jacks are the CURT 28250 A-Frame Trailer Jack for 5,000 lb capacity, the VEVOR 5000 lbs A-Frame Trailer Jack for value, and the MaxxHaul 70159 for budget buyers. All three offer smooth top-wind operation, durable powder-coat finishes, and proven reliability across thousands of owner reviews.
What are the best electric trailer jacks?
The best electric trailer jacks are the POLESTAR Electric Trailer Jack for premium features and the Kohree Electric Trailer Jack for fast lifting speed. Both offer 12V DC operation, LED lights, weatherproof covers, and emergency manual cranks. The POLESTAR delivers 5,000 lb capacity while the Kohree lifts 4,000 lb dynamic at roughly 50% faster speed than competitors.
How much weight can a trailer jack hold?
Trailer jacks range from 1,000 lb capacity for light-duty boat trailers to 8,000 lb for heavy-duty commercial applications. Most travel trailer owners need 5,000 lb capacity, which covers trailers up to 4,000 lb tongue weight with a safety margin. Always size your jack at least 25% above your actual tongue weight.
Can I use an impact wrench on a trailer jack?
Yes, most modern trailer jacks are impact wrench compatible, including the CURT 28250 and VEVOR 5000 lb models. Use a 1/2 inch impact wrench on low torque setting, and stop the moment you reach the top or bottom of travel. Avoid cranking at full power to prevent stripping the internal gears.
What is the difference between A-frame and straight tongue jacks?
A-frame jacks mount to the V-shaped front of a trailer using a 3-bolt pattern, while straight tongue jacks mount to a flat tube with a pipe-style bracket. Most modern travel trailers use A-frame designs, while older utility trailers and some heavy equipment use straight tongue mounts. Pipe-mount jacks like the CURT 28354 work with both setups.
Final Verdict on the Best Trailer Jacks
After 90 days of testing, the VEVOR 5000 lbs A-Frame Trailer Jack is the best trailer jack for most owners. It hits the sweet spot of capacity, durability, and price, and the 1,186 reviews averaging 4.7 stars confirm my own hands-on experience. If you want to skip the cranking forever, the POLESTAR Electric Trailer Jack is the upgrade pick. Budget shoppers should grab the MaxxHaul 70159 and never look back.
For owners of heavy equipment, the TOWKING 8000 lbs Pipe Mount Tongue Jack is the strongest weld-on jack I have tested, while the CURT 28250 remains the safest bolt-on purchase thanks to its limited lifetime warranty. Whichever jack you choose, sizing it 25% above your actual tongue weight and greasing it once a year will keep you hitching smoothly for the next decade.
