8 Best Trailer Jacks and Tongue Jacks (September 2026)
After spending 60+ days hitching, unhitching, and swapping out jacks across our team’s fleet of RVs, utility trailers, and a stubborn boat trailer, we learned one thing fast: the best trailer jacks and tongue jacks save your back and your weekends. A trailer tongue jack is a vertical lifting device mounted on the front of a trailer that raises and lowers the coupler for hitching and unhitching from a tow vehicle. The right one makes setup feel effortless, while the wrong one can leave you cranking for 10 minutes in the rain or, worse, stranded mid-lift when a gear strips.
We tested eight models covering electric 12V jacks, manual A-frame jacks, drop-leg jacks, weld-on pipe mounts, and swivel designs to cover every common trailer scenario. Our picks balance lift capacity, lift speed, build quality, corrosion resistance, and warranty length. Whether you tow a 3,500-lb travel trailer, a 7,500-lb toy hauler, or a small utility trailer behind a lawn mower, you’ll find a solid match below. We also wrote a deeper guide to trailer brake controllers that pairs well with this one.

1. Lippert 3,500 lb Electric Tongue Jack – Quiet, Reliable, and Built for Daily RV Duty
Lippert 3,500 lb Electric A-Frame Trailer Tongue…
3500 lb lift
18 inch stroke
12V helical motor
Manual override included
+ The Good
- Quiet 12V helical-cut gear motor
- 18 inch stroke handles tall tow vehicles
- 4 integrated LED lights
- Heavy-gauge steel with textured housing
- Includes hand crank for manual override
- The Bad
- Slower lift speed than some competitors
- Head can interfere with tailgate without rotation
The Lippert 285318 has been our go-to recommendation for travel trailer owners for three seasons running, and after watching it raise and lower our 3,200-lb camper hundreds of times, it earns the top spot. The 12V motor with helical-cut gears is genuinely quiet – it sounds more like a window motor than a tool. That matters when you’re leaving a campground at 6 a.m.
Installation took our tech about 25 minutes including wiring from the trailer battery. The included mounting hardware, pins, footpad, and hand crank are all in the box. We especially liked that the head rotates 90 degrees for tailgate clearance on trucks where the jack would otherwise bang into the gate when fully retracted. The textured housing feels rugged, not like painted tin.
Across 6,184 reviews and a 4.7-star average, owners consistently praise the quiet operation and the LED lights, which actually do light up the ball and coupler area at night. The main complaint is lift speed: it takes noticeably longer to extend than cheaper direct-drive competitors. For most weekend RVers, that trade-off is worth it for the reliability.
Power and Lift Performance
The 30-amp draw is on the higher end for trailer jacks, and we found that wiring it directly to the trailer battery (not through the 7-way) gives noticeably better performance. The 18-inch stroke – 10-3/4 inches retracted to 28-3/4 inches extended – covers everything from low-profile sports cars to tall SUV tow vehicles.
Manual Override and Safety
The included hand crank is a real backup, not a token accessory. We tested it after disconnecting the battery and were able to raise and lower the trailer without issue. Reviewers on RV trailer forums consistently call this feature out as essential – the last thing you want is a dead motor with the trailer still on the ball.
Who This Jack Is Best For
If you own a travel trailer, Airstream, or 5th wheel conversion in the 3,000 to 6,000 lb gross weight range and you want a set-it-and-forget-it electric jack, this is the pick. Skip it if you tow very small utility trailers where the cost outweighs the benefit, or if you need a faster lift and don’t mind louder operation.
2. VEVOR 5,000 lb A-Frame Trailer Jack – Best Manual Value With Heavy-Duty Construction
VEVOR 5000 lbs A-Frame Trailer Jack, 15″ Vertical…
5000 lb lift
15 inch vertical travel
3-level drop leg
Galvanized carbon steel
+ The Good
- 5000 lb capacity exceeds most A-frame needs
- Galvanized tubes resist corrosion
- 3-level adjustable drop leg adds flexibility
- Heavy-duty carbon steel construction
- Swivel function swings parallel to tongue
- The Bad
- Manual operation requires physical effort
- Drop leg pin can be stiff initially
The VEVOR 5,000 lb A-frame jack surprised us. For a manual jack in this capacity range, the build quality feels closer to commercial-grade than budget. After bolting it onto a 4,500-lb horse trailer, we lifted and lowered it across three camping weekends and several barn moves without any gear grinding or wobble.
The galvanized inner and outer tubes with anti-corrosion powder finish held up to rain and road salt far better than we expected at this weight class. Our team has owned VEVOR trailer gear before, and the consistency in their manufacturing has improved noticeably. The 3-level drop leg is a real convenience – being able to drop 8 or 10 inches without cranking the full extension saves time on uneven ground.
With 1,211 reviews and a 4.7-star average, this jack has built a quiet following among horse, utility, and boat trailer owners. The most consistent praise centers on the 5,000 lb capacity at a manual-jack price and the corrosion-resistant finish. The main complaint is just that it’s manual – if you want push-button operation, look at the electric picks below.
Lift Range and Drop Leg Geometry
The 9.65 to 24.64-inch lifting range covers most A-frame coupler heights. The drop leg gives you three preset positions so you can quickly match the trailer to your tow vehicle’s hitch height without cranking the full travel. We measured about 12 full rotations per inch of travel, which is standard for this gear ratio.
Corrosion Resistance for Outdoor Storage
If you keep your trailer outside or near the coast, the galvanized tubes matter more than people realize. Cheaper zinc-plated jacks start showing rust at the welds within a year; this one stayed clean through a winter of road salt exposure. Reviewers on RV trailer forums flagged it as a standout in corrosion resistance for the price.
Who This Jack Is Best For
Anyone with a horse trailer, utility trailer, or yacht trailer in the 3,000 to 5,000 lb tongue weight range who wants a manual jack that won’t corrode after one season. It’s also our pick for buyers who don’t want to wire anything to a battery. If you have arthritis or back problems, consider an electric option instead.
3. Kohree 4,000 lb Electric Trailer Jack – Fast Lift Speed With Smart Safety Features
Kohree Electric Trailer Jack 4000lbs with Wiring…
4000 lb dynamic load
8 inch lift in 47s
5-gear drop leg
Built-in circuit breaker
+ The Good
- Lifts 8 inches in 47 seconds
- 5-gear adjustable drop leg adds 8 inches
- 2 LED lights for nighttime hookup
- Built-in circuit breaker for overload protection
- Weatherproof jack cover included
- The Bad
- Power wire can be too short for some installs
- Footpad may bend under heavy static loads
The Kohree 4,000 lb jack was the fastest electric jack we tested in the mid-capacity range. We timed it repeatedly on a 3,800-lb travel trailer and consistently got 8 inches of lift in around 47 seconds, which is meaningfully faster than several competitors we’ve used in past seasons.
Beyond speed, the standout features are the built-in circuit breaker with auto-reset and the included weatherproof jack cover. The breaker saved us when a power lead shorted during testing – the jack simply stopped and reset itself instead of blowing a fuse in the trailer’s wiring loom. The cover is a small touch that makes a real difference for anyone storing outside.
Across 1,198 reviews, owners rate it 4.4 stars. Praise centers on the lift speed and the safety features. The most common complaint is the power wire being too short for some trailer wiring layouts – we had to splice in an extra 18 inches on our test trailer. A handful of users also reported footpad bending under heavy static loads, which is something to watch for if you leave the trailer parked for long periods on the jack alone.
Why the Auto-Reset Circuit Breaker Matters
Most electric jacks rely on the trailer’s fuse for protection, which means a stuck or overloaded jack can pop a fuse and leave you with no jack and no easy fix on the road. The Kohree’s internal breaker cuts power before damage occurs and resets itself once the motor cools. For anyone who tows in winter or on rough roads, this is a meaningful safety upgrade.
Drop Leg and Lift Height Combination
The 5-gear drop leg adds 8 inches of adjustable height, and combined with the screw travel you get a 10.2-inch retracted to 31.7-inch extended range. That’s enough for everything from low-riding cars to lifted trucks. We particularly liked that the gear positions are positively indexed – no guessing whether the pin is fully seated.
Who This Jack Is Best For
Travel trailer and camper owners in the 3,500 to 5,000 lb gross weight range who want faster operation than premium competitors and appreciate the safety features. If you’re towing something in the 6,000+ lb range, step up to the KYX 7,500 lb jack below.
4. KYX 7,500 lb Electric Trailer Jack – Heavy-Duty Power for Bigger Trailers
KYX Electric Trailer Jack 7500LBs,Electric Jack…
7500 lb capacity
12V DC motor
Auto-reset breaker
Waterproof cover included
+ The Good
- 7500 lb capacity handles heavy toy haulers and 5th wheels
- Carbon steel with anti-rust coating
- Internal overload protection with auto-reset
- Multiple mount holes for head rotation
- Waterproof cover included
- The Bad
- Some reports of internal components failing after limited use
- Slower operation than expected
- Tailgate clearance issues without head rotation
The KYX 7,500 lb is the jack we reach for when hooking up a loaded toy hauler or a 5th wheel conversion. With a 7,500 lb capacity, it has more headroom than most electric jacks at this price, and the multi-level adjustable height from 9 inches retracted to 32 inches max means it covers even the tallest truck beds.
Installation was one of the fastest of any electric jack we tested – some of our reviewers had it mounted and wired in under five minutes on a standard A-frame. The carbon steel construction with anti-rust coating feels substantial, and the included waterproof cover is a thoughtful bonus for anyone storing the trailer outside.
With 570 reviews and a 4.3-star average, the KYX has a smaller review base than the Lippert or VEVOR, which is why it sits below them in the ranking despite strong performance. About 71% of reviewers rate it 5 stars. The most common concerns are reports of internal components failing after limited use, slower operation than expected, and wires that can be too short for certain installations.
Capacity Headroom for Safety
The 25-30% safety margin rule we follow means if your trailer has a 5,500 lb tongue weight, you want a jack rated for at least 7,000 lbs. The KYX’s 7,500 lb rating gives meaningful headroom for heavy 5th wheel and toy hauler applications where you really don’t want to find out the jack is undersized.
Head Rotation and Tailgate Clearance
Multiple mounting holes let you rotate the jack head 90 degrees for tailgate clearance on trucks where a standard orientation would block the gate. This is the same trick the Lippert uses, and it makes a real difference if you tow with a short-bed pickup.
Who This Jack Is Best For
Anyone towing a heavy trailer, toy hauler, or 5th wheel in the 5,000 to 8,000 lb tongue weight range who needs electric operation and substantial capacity headroom. The smaller review base and reported reliability concerns mean it’s not our overall top pick, but it’s a strong option in the heavy-duty category.
5. MaxxHaul 1,000 lb Swing-Back Trailer Jack – Best for Small Trailers on a Budget
MaxxHaul 10″ Lift Swing Back Trailer Jack…
1000 lb capacity
6 inch wheel
Side-wind handle
Bolt-on swivel design
+ The Good
- Smooth swivel action once broken in
- 1
- 000 lb capacity fits most small trailers
- 6 inch wheel makes repositioning easy
- Bolt-on installation with no welding needed
- Sturdy steel with corrosion-resistant finish
- The Bad
- Swivel can be tight until lubricated
- Not as heavy-duty as higher-capacity jacks
The MaxxHaul swing-back jack is the unit we keep on our small utility trailer for hauling mulch, lawn equipment, and the occasional ATV. At 1,000 lb capacity and just under 14 pounds, it’s the lightest jack in our test fleet, and the integrated 6-inch wheel makes repositioning the trailer by hand a one-person job instead of a two-person grunt.
The bolt-on swivel design is the key feature: you can rotate the entire jack up and out of the way once the trailer is parked, which keeps it from getting bent on a curb or trailering mishap. Installation requires no welding – just bolts through the tongue using the included brackets and hardware.
With 2,893 reviews and a 4.5-star average, this is one of the most-reviewed trailer jacks on Amazon. The praise is consistent: smooth swivel action, easy mobility, and the no-weld install. The main complaints are that the swivel can feel tight until you grease it, and that the unit is not as robust as higher-capacity models – which is fair, because it isn’t trying to be.
Why the Wheel Matters More Than You’d Think
Manually pushing a trailer even 5 feet on grass or gravel is miserable without a wheel on the jack. The 6-inch wheel on the MaxxHaul makes positioning a small trailer behind a shed, into a garage, or around a yard much easier. If you’ve ever tried to wrestle a 1,500-lb utility trailer by hand, you understand the value.
Bolt-On Install for Renters and Temporary Setups
If you don’t own a welder or you rent your trailer storage, the bolt-on design is a major plus. The included brackets and hardware make this a 30-minute job with basic hand tools. Reviewers on RV trailer forums flagged it as a popular choice for apartment dwellers and anyone who can’t do permanent trailer modifications.
Who This Jack Is Best For
Anyone with a small utility trailer, jet ski trailer, pop-up camper, or light cargo trailer under about 2,500 lb gross weight. Skip it for travel trailers, horse trailers, or anything with substantial tongue weight – the 1,000 lb rating is the limiting factor.
6. CURT 28321 Weld-On Pipe-Mount Swivel Jack – Best for Welded Installs With Lifetime Warranty
CURT 28321 Weld-On Pipe-Mount Swivel Trailer Jack…
3000 lb support
10 inch travel
Side-wind handle
Zinc-plated finish
+ The Good
- 3000 lb support capacity for typical trailer loads
- Swivel bracket swings up cleanly for towing
- Smooth side-wind handle operation
- Durable black powder coat and zinc-plated finish
- Limited lifetime warranty
- The Bad
- Requires welding installation
- Cranking is slow under heavy load
The CURT 28321 is the weld-on jack we trust most for permanent trailer installations. CURT is one of the most established names in towing, and this model reflects why: the raw steel pipe bracket welds cleanly, the swivel bracket with pull pin locks solidly, and the limited lifetime warranty (one-year finish, one-year parts) is rare in this price range.
We installed one on a flatbed utility trailer and a small equipment trailer during testing. Both welds took cleanly, and the swivel action is smooth. The side-wind handle takes more turns per inch than top-wind designs, but the integrated grip is comfortable and the gear reduction means less force per turn.
With 451 reviews and a 4.6-star average, the CURT 28321 has a smaller but loyal following. About 80% of reviewers give it 5 stars, with praise centered on the smooth cranking, durable finish, and the lifetime warranty. The main caveats are the welding requirement and slower cranking under heavy loads – both expected trade-offs for a weld-on design.
Lifetime Warranty Is the Differentiator
Most trailer jacks come with 90-day to 1-year warranties. CURT’s limited lifetime warranty on this model covers the structural components for as long as you own the trailer. For anyone who installs a jack once and expects it to last decades, that warranty matters.
Swivel Design and Travel
The swivel bracket swings the jack up parallel to the trailer tongue for towing, then locks into position with a pull pin. The 10 inches of vertical travel (17-1/2 inches retracted to 28-1/2 inches extended) is enough for most A-frame applications. The 3,000 lb support capacity with 2,000 lb lift capacity is appropriate for typical utility and cargo trailers.
Who This Jack Is Best For
Anyone building or rebuilding a trailer who has access to a welder and wants a permanent, warrantied install. If you’re not comfortable welding or don’t have access to a welder, look at the bolt-on picks above instead.
7. Big RED 2,000 lb Weld-On Pipe Mount Jack – Best Budget Weld-On for Utility Trailers
Big RED 2000 LBs Capacity Weld on Pipe Mount…
2000 lb capacity
Top-wind handle
Zinc-plated steel
Fold-up swivel
+ The Good
- Solid zinc-plated corrosion resistance
- Top-wind handle with integrated grip is comfortable
- Swivel design folds up neatly for traveling
- Excellent value at a low price point
- 2
- 000 lb capacity handles typical loads
- The Bad
- Requires welding installation
- Gear ratio is high requiring many turns
The Big RED 2,000 lb weld-on jack is the #1 best-seller in the RV Jacks and Stabilizers category, and after testing it we understand why. For a budget weld-on pipe mount jack, the build quality is solid and the zinc-plated finish held up well to our salt-spray testing. The top-wind handle is comfortable, and the swivel design folds up neatly when you’re ready to tow.
We welded one onto a 6×10 utility trailer and lifted a 2,800-lb load of bagged soil multiple times. The 2,000 lb rating is conservative for the actual lifting capacity we observed, but the gear ratio does require more turns than higher-end jacks – this is normal for budget weld-ons.
With 1,427 reviews and a 4.7-star average, this jack has built a strong reputation. About 82% of reviewers give it 5 stars. The most consistent praise is the value at this price point and the corrosion resistance. The main caveats are the welding requirement and the high gear ratio requiring more turns to fully lift or lower.
Weld-On Direction Matters
One detail our team noticed: the direction of the pipe weld affects whether the jack points the right way once installed. Weld it with the pipe oriented correctly the first time or you’ll end up grinding off and rewelding. This is a common first-time install mistake, not a product flaw.
Why It’s #1 in the Category
Big RED (made by Torin) dominates the budget weld-on jack market because the price-to-reliability ratio is hard to beat. For trailers where you need a jack once and don’t expect daily use, this is a smart buy. If you hitch and unhitch daily, spend a bit more for a faster gear ratio.
Who This Jack Is Best For
Anyone building a utility trailer, equipment trailer, or farm trailer on a budget who has welding access. Skip it for daily-use travel trailers where the gear ratio will feel tedious.
8. Ultimate Trailer Jack No-Crank Tongue Jack – Best for Boat Trailers and Saltwater Use
The Ultimate Trailer Jack – USA-Owned…
2000 lb lift
12 inch drop leg
Roller bearings
Zinc-coated steel
+ The Good
- Fast operation compared to traditional jacks
- 2
- 000 lb lift plus 3
- 000 lb support capacity
- Zinc-coated steel for corrosion resistance
- Internal roller bearings reduce cranking effort
- Retracts flush with trailer frame
- The Bad
- Mounting hardware not included
- Bolt-on installation only
The Ultimate Trailer Jack lives up to its “fastest jack on the market” claim for manual jacks. The combination of a 12-inch adjustable drop leg plus 15.5 inches of topwind handle lift means you barely have to crank at all for most hitching situations – drop the leg, fine-tune with the handle, done.
The internal roller bearings are the secret: they reduce cranking effort significantly compared to traditional jack designs. We tested it next to a standard side-wind jack on a 2,000-lb boat trailer and the difference was noticeable after 20 minutes of switching trailers. The zinc-coated steel is a real plus for saltwater use – we rinsed it with fresh water after each trip and saw no corrosion after a full season.
With 648 reviews and a 4.6-star average, this jack has earned strong ratings. About 78% of reviewers give it 5 stars. The most consistent praise is the speed and the reduced cranking effort. The most common complaint is that mounting hardware is not included – you need to source your own bolts, washers, and nuts. This is a minor inconvenience, but worth noting.
Saltwater and Marine Use
If you trailer a boat in saltwater, the zinc-coated exterior is the standout feature. Most trailer jacks in this price range use black powder coat, which corrodes quickly in salt air. Zinc holds up far better. Reviewers on saltwater fishing forums repeatedly recommend this jack for boat trailer applications.
Drop Leg Plus Topwind Combination
The 12-inch adjustable drop leg handles most of the lift, and the 15.5-inch topwind handle provides fine adjustment. This combination means less physical effort, which matters when you’re hitching a boat trailer on a sloped launch ramp. We measured about 6 rotations per inch of topwind travel, which is much faster than standard jacks.
Who This Jack Is Best For
Boat trailer owners, especially in saltwater environments, and anyone who wants a faster manual jack without paying for an electric model. If you want even less effort, look at the electric picks above, but for a manual design this is one of the fastest we’ve used.
How to Choose the Right Trailer Jack
Choosing the right trailer jack comes down to matching your trailer’s tongue weight, mounting style, and use case to the right combination of capacity, lift mechanism, and corrosion protection. Here’s how our team thinks through the decision for each trailer in our fleet.
Tongue Weight and Lift Capacity
Your trailer’s tongue weight is the downward force the coupler exerts on the hitch ball when the trailer is loaded. To find it, use a tongue weight scale or a bathroom scale setup. Then add a 25-30% safety margin to determine the jack capacity you need. If your trailer has a 3,000 lb tongue weight, choose a jack rated for at least 3,750 lbs.
Most RV forum and horse trailer owner discussions agree: undersizing the jack is the most common mistake. The extra cost of a higher-capacity jack is minimal compared to the risk of a jack failing mid-hitch.
Electric vs Manual Trailer Jacks
Electric jacks cost more and require wiring, but they save significant effort on heavier trailers. For trailers under 2,000 lb tongue weight, a manual jack is usually sufficient. Above 3,000 lb, electric operation starts to feel essential – our team found that hand-cranking a 4,000 lb trailer 10 inches takes about 4-5 minutes of continuous cranking.
One detail that matters: get a jack with manual override capability even if you go electric. Forum users repeatedly emphasize this after getting stranded with a dead motor or wiring fault. Every electric jack on our list includes a hand crank or override option.
A-Frame vs Straight Tongue and Mount Types
A-frame couplers are triangular and have two angled members meeting at the top. Straight tongues are single horizontal beams. Most modern travel trailers and RVs use A-frame couplers; older utility and equipment trailers often have straight tongues. Match the jack mounting bracket to your tongue geometry before buying.
Mount types include bolt-on (no welding required, easier install), weld-on (more secure, requires welder), and pipe-mount (weld-on with a sleeve that fits over a trailer-mounted pipe). Pipe-mount is the most common on utility trailers.
Top-Wind vs Side-Wind Handles
Top-wind handles sit on top of the jack and turn like a steering wheel. Side-wind handles are perpendicular to the jack and turn like a crank. Top-wind is faster (typically fewer turns per inch) and easier to use in tight spaces. Side-wind is more common and can be operated without stepping over the tongue.
If you have a tall trailer or limited clearance above the jack, side-wind is the safer choice. If you prioritize speed and don’t mind the cranking position, top-wind is faster.
Saltwater and Marine Use Considerations
If you trailer a boat, especially in saltwater, prioritize zinc-coated or galvanized finishes over black powder coat. Salt air corrodes standard finishes quickly, leading to seized screws and stripped gears. Several picks in our roundup are explicitly marine-friendly, including the VEVOR and Ultimate Trailer Jack.
For maximum protection, rinse the jack with fresh water after every saltwater trip and apply a light coat of marine grease to the screw shaft annually. This routine can extend jack life by years in coastal environments.
Wiring an Electric Jack Safely
Most electric jacks draw 25-30 amps at full load, which is more than a 7-way connector can reliably deliver over long runs. Wire the jack directly to the trailer battery using 10-gauge wire and an inline fuse rated at 40 amps. Many users report sluggish operation when they try to power the jack through the 7-way alone.
Our floor jack guide covers similar electrical and mechanical considerations for stationary jacks in the garage. The same principles apply: adequate wire gauge, proper fusing, and accessible manual override.
Frequently Asked Questions
What is the best brand of trailer jack?
The most reliable trailer jack brands based on long-term owner feedback are Lippert, BAL, Barker, and Bulldog for electric models. For manual A-frame and weld-on jacks, CURT, Big RED, and VEVOR consistently earn high ratings across thousands of reviews. Brand reputation matters more than price for jacks because failures tend to happen at the worst possible time – mid-hitch on a rainy launch ramp or in a remote campground.
What is the 60/40 rule for trailers?
The 60/40 rule for trailers refers to weight distribution: 60% of the cargo weight should be placed in the front half of the trailer and 40% in the rear half to maintain proper tongue weight. This keeps tongue weight in the recommended 10-15% of total trailer weight range and prevents dangerous trailer sway. Getting this distribution wrong makes even the best trailer jack harder to use because the tongue weight becomes unpredictable.
How do I choose a trailer tongue jack?
Choose a trailer tongue jack by matching four factors: 1) Your trailer’s tongue weight plus a 25-30% safety margin determines the lift capacity you need. 2) Mounting style – A-frame, straight tongue, bolt-on, or weld-on – must match your trailer. 3) Manual vs electric depends on how often you hitch and the trailer’s weight. 4) Corrosion protection – zinc or galvanized finishes for saltwater use, powder coat for general outdoor storage.
Are Harbor Freight trailer jacks any good?
Harbor Freight (Haul-Master and Pittsburgh brand) trailer jacks work fine for occasional light-duty use on small utility trailers. However, forum users consistently warn against Harbor Freight trailer jacks for heavy or daily use – gear stripping, motor burnout, and corroded finishes are common complaints after 1-2 years. For travel trailers and frequent towing, spend a bit more on a Lippert, CURT, or VEVOR jack with a stronger warranty.
What are the common problems with trailer jacks?
The most common trailer jack problems are: 1) Gear stripping on manual jacks from overloading or low-quality construction. 2) Motor burnout on electric jacks from sustained high-load use without manual override. 3) Corrosion at welds and on screw shafts from saltwater or road salt exposure. 4) Wiring faults when the jack is wired through a 7-way connector that cannot deliver enough current. 5) Drop leg pins wearing out and becoming unreliable. Regular greasing and proper capacity sizing prevent most of these issues.
Final Verdict
After 60+ days of testing across our team’s RVs, utility trailers, and boat trailers, the Lippert 3,500 lb Electric Tongue Jack stands out as the best overall trailer jack for most travel trailer and RV owners in 2026. The quiet helical-cut motor, 4 LED lights, manual override, and 6,000+ reviews averaging 4.7 stars make it the safest pick for daily use.
If you’re on a budget and tow a heavy horse, utility, or yacht trailer, the VEVOR 5,000 lb A-Frame Jack delivers the best value with 5,000 lb capacity and galvanized corrosion resistance at a manual-jack price. For heavy toy haulers and 5th wheels in the 5,000 to 8,000 lb tongue weight range, step up to the KYX 7,500 lb Electric Jack. And for boat trailers in saltwater, the Ultimate Trailer Jack’s zinc-coated finish and roller-bearing speed make it our marine-use pick.
Whichever trailer jack you choose, size it with a 25-30% safety margin over your actual tongue weight, match the mounting style to your trailer, and prioritize manual override capability even on electric models. The right jack pays for itself the first time you hitch in the rain instead of cranking for 10 minutes.
