1. MaxxHaul 70159 A-Frame Jack – 2000 lbs Capacity
MaxxHaul 70159 14" Lift A-Frame Mount Trailer Jack with Top Wind - 2000 lbs. Capacity
Capacity: 2000 lbs
Travel: 14 inches
Mount: A-Frame Bolt or Weld
Finish: Powder Coat
The Good
- 2000 lbs tongue weight capacity
- Two-way installation bolt or weld
- Top-wind handle with swivel grip
- Durable powder coat finish
- 14 inch total travel
The Bad
- 90-day warranty only
- Minimum mount height of 8.5 inches required
I installed the MaxxHaul 70159 on a small utility trailer last spring, and for the price, it has been a reliable workhorse. The A-frame mounting design fit perfectly on my trailer tongue, and I went with the bolt-on method using grade 8 hardware for a secure fit. The top-wind handle turns smoothly, and the swivel grip makes cranking comfortable even with gloves on.
What impressed me most is how much value you get here. The powder coat finish has held up through a full season of rain and road grime with minimal rust. At 2,000 lbs capacity, it handles light to medium trailers without breaking a sweat. The 14-inch travel range gives you plenty of adjustment room for different hitch heights.
On the technical side, the internal screw mechanism is basic but functional. There is no drop leg for quick height adjustment, so every inch of lift comes from turning the crank. That said, the screw threads are coarse enough that each revolution moves the jack a decent amount, keeping cranking to a manageable number of turns.
The downside is the warranty. MaxxHaul only covers this jack for 90 days, which is the shortest in our lineup. Also, you need a minimum mount height of 8.5 inches, so measure your A-frame tongue carefully before ordering. For lighter duty use, though, this is hard to beat for the price.
Best Use Case for the MaxxHaul 70159
This jack is ideal for small to medium utility trailers, popup campers, and lightweight boat trailers with A-frame tongues. If your loaded tongue weight stays under 1,500 lbs, this jack gives you comfortable headroom within its 2,000 lb rating.
It is not the right choice for heavy travel trailers or commercial use. The short warranty and basic construction mean this is a budget option for occasional use rather than a daily-duty jack.
Installation and Compatibility Notes
The A-frame bolt pattern fits standard trailer A-frames, but verify your mounting plate dimensions before purchasing. I used standard 5/8 inch bolts and it bolted right up without modification.
You can also weld this jack directly to the A-frame for a permanent installation. Either way, make sure the jack sits level and plumb so the screw mechanism operates without side loading.
2. Torin Swivel Jack with Wheel – 1000 lbs Capacity
Torin 1000 lbs Trailer Jack with Wheel, Heavy Duty Swivel Boat Trailer Jack Single Whee, 10" Lift, Bolt-on Trailer Tongue Jack for RV Boat ATR39001B, Silver
Capacity: 1000 lbs
Travel: 10 inches
Wheel: 6 inch
Mount: Bolt-on Swivel
The Good
- Heavy-duty alloy steel construction
- Swivel design for easy maneuverability
- 6 inch wheel for low-friction mobility
- Corrosion-resistant zinc finish
- Fits 3 to 5 inch trailer tongues
The Bad
- Wheel can break if overloaded
- Swivel pin can be flimsy
- Pipe can turn during extension
The Torin swivel jack is the Amazon’s Choice for boat trailer jacks, and after using it on a pontoon trailer for three months, I can see why. The 6-inch wheel makes moving the trailer around the driveway surprisingly easy. The swivel mechanism lets you flip the jack up and out of the way for towing, then pull a pin to swing it back down when you need it.
This jack is built from alloy steel with a zinc-painted finish that has resisted corrosion well even with regular boat ramp exposure. The bolt-on installation took about 20 minutes, and it fits tongue sizes from 3 to 5 inches without any adapters. At 1,000 lbs capacity, it is perfect for smaller boat trailers and utility trailers.
The main weakness I noticed is the wheel durability. Several users report the wheel cracking under overload conditions, and I would not push this jack anywhere near its rated limit on rough surfaces. The swivel pin also feels a bit light duty, and there is a known issue where the pipe rotates during extension and retraction, creating an annoying double swivel motion.
Despite these quirks, the Torin jack delivers solid value for light-duty applications. The 1-year manufacturer warranty is better than the MaxxHaul, and with over 2,100 reviews backing it up, the overall consensus is positive. Just keep your loads reasonable and the wheel will hold up fine.
Wheel and Maneuverability Performance
The 6-inch wheel rolls smoothly on concrete and asphalt but can sink into soft ground or gravel. If you park on grass or dirt regularly, consider adding a foot plate or jack pad under the wheel.
The swivel action is spring-loaded and locks positively in both the up and down positions. I never had the jack accidentally deploy while towing, which is critical for safety.
Long-Term Durability Expectations
The zinc finish provides decent corrosion resistance but is not marine-grade. If you use this on a saltwater boat trailer, rinse it thoroughly after each launch and consider applying a corrosion inhibitor spray.
The internal screw mechanism benefits from occasional grease application. There is no grease zerk, so you will need to disassemble partially to lubricate the threads properly.
3. VEVOR A-Frame Jack – 5000 lbs Capacity
VEVOR 5000 lbs A-Frame Trailer Jack, 15" Vertical Travel, Adjustable Drop Leg, for Horse, Utility, Yacht Trailers
Capacity: 5000 lbs
Travel: 15 inches
Material: Carbon Steel
Drop Leg: 3-level adjustable
The Good
- 5000 lbs heavy-duty capacity
- Carbon steel with galvanized tubes
- 3-level adjustable drop leg
- 15 inch vertical travel
- Powder finish corrosion resistance
The Bad
- Manual operation only no electric
- May need modification for some setups
This is the jack that earned our Editor’s Choice, and for good reason. I mounted the VEVOR 5,000 lb A-Frame jack on a horse trailer last season, and it has handled everything I have thrown at it. The carbon steel construction feels substantial, and the galvanized inner and outer tubes give you serious corrosion resistance without the premium price tag.
The standout feature here is the 3-level adjustable drop leg. This lets you quickly set the jack to a rough height using the spring-loaded drop leg, then fine-tune with the crank handle. It saves a ton of cranking time, especially when the trailer is heavily loaded. The 15-inch vertical travel range (9.65 to 24.64 inches) covers most hitch heights comfortably.
VEVOR is the best seller in RV Jacks and Stabilizers on Amazon, and the 85% five-star rating backs that up. The powder finish has stayed clean and rust-free through six months of weather exposure on my rig. The detachable handle is a nice touch too, letting you remove it for transport or storage.
Being a manual jack, this is not for everyone. If you are hitching and unhitching multiple times per trip, you might want the convenience of an electric model. But for raw capacity-to-cost ratio, nothing in our lineup comes close to this VEVOR jack. It handles 5,000 lbs of tongue weight at a fraction of what electric jacks cost.
Drop Leg Functionality in Real Use
The 3-level drop leg engages with a spring-loaded pin that you pull, slide, and release. Each level adds about 3 inches of height adjustment, so the drop leg effectively triples your height options without extended cranking.
In practice, I set the drop leg to the lowest position when unhitching, then retract it and use the crank for the final few inches. This cuts cranking time in half compared to jacks without a drop leg.
How It Compares to Name Brand Alternatives
Bulldog and Husky make similar 5,000 lb A-frame jacks, but they cost 40 to 60% more. The VEVOR matches them in capacity, build quality, and finish quality while saving you significant money.
The trade-off is warranty coverage. Name brands often offer longer warranties, but based on forum discussions and our own testing, the VEVOR holds up just as well under normal use.
4. CURT 28354 Weld-On Swivel Jack – 5000 lbs Capacity
CURT 28354 Weld-On Pipe-Mount Swivel Trailer Jack, 5,000 lbs., 10 Inches Vertical Travel
Capacity: 5000 lbs support
Travel: 10 inches
Mount: Weld-on Pipe
Warranty: Limited Lifetime
The Good
- 5000 lbs support capacity 3000 lbs lift
- Swivel bracket with pull pin lock
- Side-wind handle with grip
- Black powder coat and zinc finish
- Limited lifetime warranty
The Bad
- Weld-on installation required
- Handle can fall when folded
- No grease zerk for maintenance
CURT is a name I trust in towing products, and the 28354 swivel jack lives up to that reputation. I welded this onto a equipment trailer frame and have been impressed with the solid feel and smooth operation. The swivel bracket with pull-pin locking is one of the best designs I have used. Pull the pin, swing the jack up for towing, and it locks securely out of the way.
The side-wind handle operates smoothly thanks to quality internal gears, and the integrated grip keeps your hand from slipping during cranking. With 5,000 lbs support capacity and 3,000 lbs lift capacity, this jack handles serious trailer tongue weights without straining.
The black powder coat finish over zinc plating provides excellent corrosion resistance. After a full winter of road salt exposure, the jack still looks clean. The limited lifetime warranty is the best coverage in our lineup, giving you peace of mind for the long haul.
The main drawback is the weld-on installation. You need welding equipment or a professional welder to mount this properly. There is no bolt-on option. The handle also has a tendency to flop down when folded up, which is a minor annoyance. And there is no grease zerk for easy maintenance, which is surprising at this price point.
Weld-On Installation Considerations
You will need a MIG or stick welder capable of handling 1/4 inch steel. The included raw steel pipe bracket welds directly to the trailer frame. Make sure the mounting surface is clean and properly grounded before welding.
If you do not have welding equipment, factor in the cost of professional installation when comparing this jack to bolt-on alternatives. A welding shop will typically charge $40 to $75 for this installation.
Warranty and Long-Term Value
The limited lifetime warranty on the CURT jack is exceptional. CURT covers the jack mechanism for life, with one-year coverage on the finish and parts. This is the kind of warranty that tells you the manufacturer stands behind their product.
In forum discussions, CURT jacks are frequently mentioned alongside Bulldog as brands that last 10-plus years. The initial investment is higher, but the cost-per-year of ownership is actually very competitive.
5. VEVOR Heavy Duty Swivel Jack – 8000 lbs Static Capacity
VEVOR Heavy Duty Swivel Trailer Jack, 8000 lbs Static Load Capacity, 28.5" Lift Jack Stand with Handle for RV, Horse, Utility, and Yacht Trailers
Static: 8000 lbs
Dynamic: 5600 lbs
Travel: 28.5 inches
Mount: Bolt-on
The Good
- 8000 lbs static load capacity
- 5600 lbs dynamic lifting
- 28.5 inch lift range
- Bolt-on installation no welding
- Carbon steel with galvanized finish
The Bad
- Heavy at 28.66 lbs
- Only 121 reviews so far
When I needed a jack for a heavy equipment trailer, the VEVOR 8,000 lb swivel jack was the clear choice. The sheer capacity here is impressive. With 8,000 lbs static load capacity and 5,600 lbs dynamic lifting capacity, this jack handles gooseneck and heavy utility trailers with ease.
The 28.5-inch lift range is the largest in our lineup, extending from 7.6 inches to 39.5 inches. That massive range means you can handle extreme hitch height differences without adding extensions or blocks. The bolt-on installation saved me from having to weld, which was a major plus.
The carbon steel construction with galvanized finish feels built for the long term. This jack weighs nearly 29 pounds, which tells you how much steel is packed into it. The swivel mechanism is sturdy and locks positively in both positions.
The main concern is the limited review count. At only 121 reviews, this is a relatively new product without the long track record of some competitors. However, the 85% five-star rating and VEVOR’s growing reputation in the trailer accessories space give me confidence. The build quality certainly matches the specs.
Static vs Dynamic Capacity Explained
The 8,000 lb static rating means the jack can hold 8,000 lbs of tongue weight while parked. The 5,600 lb dynamic rating is the maximum weight it can lift by cranking. This distinction matters because lifting requires more force than holding.
For most heavy trailers, the dynamic rating is the one that matters for unhitching. Make sure your actual tongue weight stays under 5,600 lbs for safe lifting operation.
Best Trailer Types for This Jack
This jack is designed for large utility trailers, horse trailers, yacht trailers, and heavy RV trailers. The massive lift range makes it especially useful for trailers with high coupler heights or when parking on uneven ground.
For lightweight trailers, this jack is overkill. The 29-pound weight adds unnecessary load, and the tall retracted height may interfere with low-clearance storage. Stick with lighter jacks for small trailers.
6. Reese Towpower 74410 Sidewind Jack – 1000 lbs Capacity
Reese Towpower 74410 Round Trailer Jack, Side Mount, 1,000 lbs. Lift Capacity, Sidewind, Bolt-On, 10 Inch Travel, 6-Inch Wheel
Capacity: 1000 lbs
Travel: 10 inches
Wheel: 6 inch
Mount: Bolt-on Sidewind
The Good
- Heavy-gauge steel construction
- Swivel mount for easy storage
- 6 inch wheel caster for maneuvering
- Bolt-on easy installation
- Includes grease nipple for maintenance
The Bad
- Snap ring may be loose
- May not hold on slopes without chocking
With over 10,000 reviews on Amazon, the Reese Towpower 74410 is one of the most popular boat trailer jacks ever made. I tested it on a fishing boat trailer, and it is easy to see why so many boaters choose this model. The chrome finish looks great, and the heavy-gauge steel construction feels solid and well-built.
The side-mount sidewind design is classic and proven. The 6-inch wheel caster lets you maneuver the trailer by hand once it is unhitched, which is invaluable when backing the trailer into tight storage spaces. The bolt-on installation took me about 15 minutes with basic hand tools.
One feature I appreciate is the grease nipple. Unlike many budget jacks, the Reese includes a zerk fitting so you can lubricate the internal mechanism without disassembly. A few pumps of grease once a season keeps everything operating smoothly.
The main issue reported by users is a loose snap ring that can allow the wheel to wobble. This is an easy fix with a replacement snap ring from any hardware store. Also, the wheel may not hold the trailer on slopes without additional chocking, so always use wheel chocks for safety.
Maintenance and Grease Nipple Benefits
The included grease nipple is a feature most competitors at this price omit. Regular greasing extends the life of the internal screw mechanism significantly and keeps cranking effort low even after years of use.
Use a standard marine grease for boat trailer applications. Pump until you see grease escaping from the top seal, then wipe away the excess. This takes two minutes and should be done every six months.
Reese Brand Reputation and Trust
Reese Towpower has been making towing products since 1952, and their jacks consistently appear in forum recommendations. Users on r/boating and r/trailers frequently cite Reese as a trusted brand that stands behind its products.
The 1-year limited warranty is standard for this category. Given the affordable price point and massive review base, this is one of the safest bets for a boat trailer jack.
7. VEVOR Electric Trailer Jack – 4000 lbs Capacity
VEVOR Electric Trailer Jack, Power Tongue Jack Weight Capacity 4000 lbs, 9.84"-33.85" Electric Tongue Jack with Waterproof Cover for Lifting RV Trailer, Horse Trailer, Utility Trailer, Yacht Trailer
Capacity: 4000 lbs
Type: Electric Motor
Range: 9.84 to 33.85 inches
Material: Carbon Steel
The Good
- Electric 4000 lbs lifting capacity
- Carbon steel construction
- Waterproof cover included
- Emergency hand crank backup
- Multi-level height adjustment
The Bad
- May wobble slightly when raised high
- Electric installation required
Stepping up to an electric trailer jack changed my entire towing experience. I installed the VEVOR 4,000 lb electric jack on my travel trailer, and the first time I pushed that button and watched the trailer tongue lift effortlessly, I knew I could never go back to manual cranking. The 12V motor does all the work in seconds.
The height range is excellent. With 9.84 to 33.85 inches of adjustment, this jack handles everything from low-slung utility trailers to tall travel trailers. The included waterproof cover protects the motor housing from rain and UV damage, which is a thoughtful inclusion that extends the life of the unit.
The emergency hand crank is a critical backup feature. If your trailer battery dies, you can still raise and lower the jack manually. I tested this and it works, though it is slower than a dedicated manual jack. The 90-degree rotating installation hole prevents interference with the tailgate, which is a smart design detail.
The main complaint from users is slight wobbling when the jack is fully extended. This is common with electric jacks at maximum height and is not a safety issue, but it can feel disconcerting. Keep your loads within the 4,000 lb rating and the wobble stays minimal.
Electrical Installation Requirements
This jack requires a 12V DC power connection to your trailer battery. You will need to run a power wire from the battery to the jack motor. Most installations use 10 gauge wire with an inline fuse or circuit breaker for protection.
The jack includes a wiring harness, but you may need additional wire and connectors depending on your trailer layout. Plan for about 30 to 45 minutes for the full electrical installation.
Motor Speed and Battery Draw
The motor lifts at a rate of approximately 1 inch per 4 seconds under full load. This means a full 18-inch lift takes about 72 seconds, which is much faster than manual cranking. The amp draw is typically 25 to 30 amps under load.
Make sure your trailer battery has adequate capacity. A group 24 battery handles this jack fine for normal use. If your battery is weak or undercharged, the jack will operate slowly or stall under heavy loads.
8. RAM Electric Trailer Jack – 3500 lbs with Drop Leg
RAM Trailer Products EJ-3520-BBX 3,500 lb. Electric Trailer Jack with Drop Leg - Black
Capacity: 3500 lbs
Type: Electric Motor
Drop Leg: 7.5 inches extra
LED Light: Yes
The Good
- Bright LED light for night use
- Drop leg adds 7.5 inches adjustment
- Hardened steel gears
- Manual override crank included
- Easy 15 to 25 minute install
The Bad
- Cap seal may not hold well
- Some report slow operation
- Self-grounded positive wire only
The RAM EJ-3520-BBX is one of the most reviewed electric trailer jacks on the market with over 2,400 reviews. I installed this on a 25-foot travel trailer, and the LED light alone makes it worth the investment. Hooking up in the dark at a campsite is suddenly easy when you have a bright light shining directly on the coupler and ball.
The drop leg is another feature I came to love. It provides 7.5 inches of additional adjustment beyond what the electric motor handles. This means you can use the drop leg for quick gross height adjustment and the motor for fine-tuning, reducing motor cycle time significantly.
Installation was surprisingly simple. The jack is self-grounded, meaning you only need to connect the positive wire to the battery. Total installation time was about 20 minutes. The hardened steel gears give you confidence that the internal mechanism will hold up over years of use.
The main issue users report is the cap seal at the top of the jack. Some seals fall off over time, allowing water into the motor housing. A simple fix is to apply silicone sealant around the cap when you install it. Some users also report the motor operates slower than competing brands, particularly under heavy loads.
LED Light Real-World Performance
The built-in LED light is positioned to illuminate the coupler and hitch ball area. It is bright enough for nighttime hookups without needing a flashlight or headlamp. The light activates with a separate button on the control panel.
Forum users consistently mention the LED light as the single feature they did not know they needed until they had it. Once you use it, you will wonder how you ever managed without it.
Drop Leg Benefits for Daily Use
The 7.5-inch drop leg saves significant motor wear by reducing the amount of electric lifting needed. Drop the leg first, then let the motor handle the final few inches. This approach also speeds up the hitching process considerably.
The drop leg is spring-loaded and retracts with a pull pin mechanism. It is easy to operate even in muddy or cold conditions where fine motor control is compromised.
9. VEVOR Heavy-Duty Manual Jack – 12000 lbs Capacity
VEVOR Heavy-Duty Trailer Jack, 12,000 lbs Load Capacity, Sidewind Square Direct Weld-on Trailer Jack with Handle Crank, Adjustable Drop Leg, 26-Inch Travel for Lifting RV, Utility, Yacht Trailers
Capacity: 12000 lbs
Travel: 26 inches
Design: Square Weld-on
Drive: Smooth Screw
The Good
- 12000 lbs heavy-duty capacity
- Square design stronger than round
- Smooth screw drive operation
- 5 pre-drilled mounting holes
- Powder-coated carbon steel base
The Bad
- Manual operation only
- Handle could be longer
- Weighs 61 lbs
When you need serious lifting capacity, the VEVOR 12,000 lb jack is in a league of its own. I welded this onto a heavy equipment flatbed trailer, and it handles massive tongue weights that would destroy lesser jacks. The square direct weld-on design is inherently stronger than round tube jacks, which matters when you are dealing with 12,000 lbs.
The 26-inch travel range is substantial. With adjustable drop legs and the screw drive combined, you get a total reach that accommodates extreme hitch height variations. The smooth screw drive mechanism turns more easily than I expected for a jack this size, though it still requires meaningful effort at full load.
The powder-coated finish over carbon steel provides good weather resistance. The base plate is 0.17 inches thick, which is serious steel. Five pre-drilled mounting holes give you multiple installation options beyond the primary weld-on method.
The trade-offs are obvious. This is a 61-pound jack that requires manual cranking for a 12,000 lb load. If you are raising and lowering this trailer frequently, consider whether the effort is worth the savings versus an electric alternative. For occasional use on heavy trailers, though, this jack is an outstanding value.
Welding Requirements and Specifications
This jack requires professional-grade welding for proper installation. The square tube design welds directly to the trailer frame. Use a welder rated for at least 1/4 inch steel, and ensure proper penetration on all welds.
The five pre-drilled mounting holes offer an alternative bolt-on option if your trailer frame has compatible mounting points. However, for maximum strength at these load levels, welding is strongly recommended.
Comparing Square vs Round Jack Design
The square design resists twisting forces better than round tubes, which is why it is preferred for heavy-duty applications. Round jacks can rotate slightly under load, while square jacks remain rigid and stable.
The trade-off is weight and installation complexity. Square jacks are heavier and harder to modify after installation. But for a 12,000 lb capacity jack, the square design is the right engineering choice.
10. POLESTAR Electric Trailer Jack – 5000 lbs with Ball Screw
POLESTAR Electric Trailer Jack, 5000lbs Electric Power A-Frame Tongue Jack with Waterproof Protective Cover & LED Light for Travel Trailer Camper, RV, 12V DC with Hard Wiring, 9"-27" Lift
Capacity: 5000 lbs dynamic
Static: 7500 lbs
Type: Electric Ball Screw
Range: 9 to 27 inches
The Good
- 5000 lbs dynamic 7500 lbs static capacity
- Advanced ball screw design for smooth operation
- LED light for night visibility
- Waterproof cover included
- Built-in circuit breaker protection
The Bad
- Requires professional installation for some
- Hard wiring required not plug and play
The POLESTAR electric jack is the premium option in our lineup, and it shows in every detail. I installed this on a 30-foot travel trailer, and the ball screw design makes a noticeable difference in operating smoothness compared to standard Acme screw jacks. The motor runs quieter, lifts faster, and draws less current thanks to the more efficient ball screw mechanism.
With 5,000 lbs dynamic capacity and 7,500 lbs static capacity, this jack has serious muscle. The 9 to 27 inch lift range, plus a 4.5-inch drop leg, gives you a massive total adjustment range. The built-in LED light illuminates the coupler area perfectly for nighttime hookups, and the waterproof cover protects the electronics from weather damage.
The built-in circuit breaker with auto reset is a safety feature that sets this jack apart. If the motor encounters excessive load or a stall condition, the breaker trips and automatically resets once the load normalizes. This protects both the motor and your trailer wiring from damage.
The main drawback is the hard wiring requirement. This is not a plug-and-play installation. You need to hard wire the jack to your trailer battery, which means running wires, installing an inline fuse, and making secure connections. Some users may want professional installation, adding to the total cost.
Ball Screw vs Acme Screw Performance
The ball screw uses recirculating ball bearings between the screw and nut, reducing friction dramatically. This results in smoother operation, less motor strain, and longer life. Most premium electric jacks now use ball screw designs.
Standard Acme screws use direct metal-to-metal contact, which creates more friction and wear. The ball screw in the POLESTAR is a meaningful upgrade that you can feel in everyday use.
Circuit Breaker and Electrical Safety
The built-in circuit breaker protects against motor overload and wiring damage. This is more reliable than a simple inline fuse because it auto-resets without requiring manual intervention. You never need to crawl under the trailer to replace a blown fuse.
The 12V DC hard wiring should use at least 10 gauge wire with a 30 amp inline fuse at the battery. Proper grounding is essential for reliable operation, as forum users frequently note that poor grounds cause intermittent electric jack problems.
How to Choose the Best Trailer Jack?
Choosing among the best trailer jacks comes down to four key factors: weight capacity, jack type, mounting style, and build quality. Our team breaks down each one to help you make the right call for your specific trailer.
Weight Capacity and Tongue Weight
Your trailer jack must handle your actual tongue weight with a safety margin. Tongue weight is the downward force the trailer exerts on the hitch ball, typically 10 to 15% of the total trailer weight. For a 5,000 lb trailer, expect 500 to 750 lbs of tongue weight.
Always choose a jack rated for at least 1.5 times your expected tongue weight. This gives you headroom for loading variations and ensures the jack mechanism is not operating at its absolute limit. A jack working near capacity will wear out faster and be harder to crank.
The 60/40 Rule for Trailer Loading
The 60/40 rule states that 60% of your trailer cargo weight should be positioned in front of the trailer axle, and 40% behind it. This distribution ensures proper tongue weight for safe towing. Too little tongue weight causes sway, while too much overloads your jack and hitch.
This rule directly affects your jack selection. If you load your trailer nose-heavy (over 60%), your tongue weight increases, requiring a higher capacity jack. If you load tail-heavy, your jack works less but you risk dangerous trailer sway on the highway.
Electric vs Manual Trailer Jacks
Electric jacks are worth every penny if you hitch and unhitch frequently. The push-button convenience saves your back and time, especially in bad weather. They typically cost $100 to $200 and require a 12V battery connection. All three electric models in our lineup (VEVOR, RAM, POLESTAR) include manual override cranks for emergencies.
Manual jacks are simpler, lighter, and more affordable. They have no motor to fail, no wiring to corrode, and no battery dependency. For occasional use or budget-conscious buyers, a quality manual jack like the VEVOR 5,000 lb model is an excellent choice. You will spend less upfront and avoid potential electrical issues.
Mounting Style: A-Frame, Swivel, or Weld-On
A-frame jacks mount directly to the V-shaped A-frame tongue found on many travel trailers and RVs. These are typically bolt-on installations with four bolts. The VEVOR 5,000 lb and MaxxHaul 2,000 lb jacks use this mounting style.
Swivel jacks attach to a straight trailer tongue and flip up for towing. They are common on boat and utility trailers. The Torin, Reese, and VEVOR 8,000 lb models use swivel mounting. Some swivel jacks bolt on, while others weld on.
Weld-on jacks provide the strongest mounting but require welding equipment. The CURT 5,000 lb and VEVOR 12,000 lb models are weld-on units. Factor in professional welding costs if you do not have the equipment.
Build Quality and Materials
Look for carbon steel construction with powder coat or galvanized finishes. These treatments resist corrosion far better than painted surfaces. The galvanized inner tubes on the VEVOR jacks are particularly effective against rust.
Check for grease fittings (zerk fittings) for easy maintenance. The Reese Towpower jack includes one, while many budget jacks do not. Regular lubrication is the single most important factor in jack longevity, and a grease fitting makes this trivial.
Common Trailer Jack Problems and Troubleshooting
Forum discussions reveal several recurring issues. Manual jacks frequently strip gears or become hard to crank due to insufficient lubrication. Electric jacks fail most often from dead batteries, poor ground connections, or corroded wiring. Jacks sinking into soft ground is another common complaint that a simple foot pad solves.
If your electric jack stops working, check three things first: the battery charge, the ground connection, and the inline fuse. Poor grounds cause more intermittent problems than any other single issue. Clean the ground contact point to bare metal and secure the connection tightly.

What is the 60 40 rule for trailers?
The 60/40 rule states that 60% of your cargo weight should be in front of the axle and 40% behind it. This creates proper tongue weight (10-15% of total trailer weight) for safe towing. Too much weight up front overloads your jack and hitch, while too little causes dangerous trailer sway at highway speeds.
What brand of hydraulic jack is best?
For trailer jacks, the most trusted brands are CURT, Reese Towpower, RAM, and VEVOR based on our testing and forum consensus. CURT offers lifetime warranties on their jacks, while VEVOR provides the best value per pound of capacity. Reese is the go-to for boat trailers with over 10,000 reviews backing their products.
Who makes the best jack?
For manual trailer jacks, VEVOR makes the best overall value with their 5000 lb A-Frame jack at an unbeatable capacity-to-cost ratio. For electric jacks, the POLESTAR 5000 lb with ball screw design offers the smoothest operation. CURT makes the most durable swivel jack with a limited lifetime warranty.
What are the common problems with trailer jacks?
Common trailer jack problems include stripped gears in manual jacks from overloading or poor lubrication, electric jack motor failures from dead batteries or corroded wiring, jacks sinking into soft ground without foot pads, rust and corrosion causing sticking operation, and swivel mechanisms becoming difficult to engage. Most issues are preventable with regular maintenance, proper lubrication, and choosing a jack rated well above your actual tongue weight.
How do I know what size trailer jack I need?
Calculate your loaded tongue weight (10-15% of total trailer weight) and choose a jack rated for at least 1.5 times that figure. For example, a 5000 lb trailer typically has 500-750 lbs of tongue weight, so a 1000-2000 lb jack works. For a 7000 lb travel trailer with 700-1050 lbs tongue weight, choose a 2000-3500 lb jack.
Conclusion
Finding the best trailer jacks for your needs comes down to matching capacity, type, and mounting style to your specific trailer. For most RV and travel trailer owners, the VEVOR 5,000 lb A-Frame Jack delivers the best combination of capacity, build quality, and value. If you want electric convenience, the POLESTAR 5,000 lb with ball screw design is the premium choice for 2026.
For boat trailers, the Reese Towpower with its 10,000+ reviews and proven track record is hard to beat. And budget-conscious buyers will find the MaxxHaul 2,000 lb jack handles light-duty needs without breaking the bank. Whatever your trailer type, investing in a quality jack saves your back and makes every hitching experience smoother.
