Best Electric Trailer Tongue Jacks
Five documented powered A-frame jack options, compared by lifting capacity, real operating travel, power arrangements and installation tradeoffs.
Compare Current OptionsAn electric tongue jack saves cranking, but the wrong one can hit a tailgate, run out of extension on sloped ground or strain an undersized circuit. This guide focuses specifically on powered A-frame tongue jacks, not stabilizers, landing gear or general-purpose side-mount trailer jacks. Product specifications are sourced from named model pages rather than assumed from similarly branded versions.

Check Price04 Seven fitment and safety checks
Complete these checks before spending money or removing your existing jack.
- Measure actual tongue load: Use a suitable scale or verified measurement method; trailer gross weight is not the tongue weight and does not determine the required jack rating.
- Confirm A-frame mounting: Compare mounting hole pattern, center opening and jack tube diameter to the exact replacement instructions.
- Check retracted and extended heights: Account for hitch ball height, ground slope, footplate and the amount of drop-leg extension; total travel is not motor stroke.
- Inspect tailgate and propane-tank clearance: Check the jack motor head with the tow vehicle fully articulated and tailgate open; a rotated installation may not solve every conflict.
- Verify 12-volt power and fuse: Follow the specific manual for wire gauge, circuit protection, grounding and battery or tow-vehicle power compatibility.
- Plan for manual override: Know where the emergency crank fits and keep it accessible; test operation with the trailer securely supported.
- Use level, load-bearing ground: Chock wheels before uncoupling, place the foot on a stable surface and never use the tongue jack as a person-supporting lifting device.
05 Choose by actual requirements
For standard A-frame replacement: First match the mounting dimensions and loaded tongue weight. Compare Lippert 285318 with BULLDOG 500187 if you prefer a conventional 3,500-pound powered jack.
For limited battery access: Lippert Power Stance supports an optional manufacturer-specific tow-vehicle power accessory. Verify your vehicle and cord setup before treating this as a backup.
For changing campsite elevations: Look closely at Stromberg Carlson JET-3755’s powered stroke plus drop leg. Measure both the minimum hitching height and the maximum required lift.
For heavier tongue loads: Consider the JET-5000 only after confirming its 5,000-pound rating, electrical installation, and A-frame fit.

06 Frequently asked questions
Is a 3,500-pound electric jack enough for a travel trailer?
Often, but only after checking actual loaded tongue weight and the manufacturer’s rated lifting capacity. Do not compare the jack rating directly to the trailer’s total GVWR.
What is the difference between stroke and total travel?
Stroke is the jack’s powered vertical movement. Total travel may add a telescoping drop leg, so two products with similar total reach can behave differently.
Can I power an electric tongue jack from the tow vehicle?
Only with a manufacturer-approved arrangement and adequate wiring. Lippert offers an optional Power Swap cord for its Power Stance system; do not assume any jack accepts a standard trailer plug.
Will a new jack fit my existing A-frame bolt holes?
Many use common A-frame patterns, but tube diameter, bolt spacing, head orientation and interference must be checked against both trailer and jack documentation.
What happens if the battery is dead?
The reviewed models document manual override provisions, but the location and required crank vary. Read the manual and practice safely before a trip.
Should I buy a 5,000-pound jack for a lighter trailer?
Extra rated capacity can be useful, but it does not compensate for poor mounting fit, insufficient reach or inadequate electrical supply. Select on measured requirements.
07 The right powered jack fits first
Start with actual loaded tongue weight, available mounting clearance and required operating heights. For versatility, the Power Stance has a documented optional power accessory; for a stated longer limited warranty, BULLDOG 500187 stands out; for higher rated lifting capacity, investigate the JET-5000. None is a substitute for safe chocking, stable ground and a correct 12-volt installation.
