Best RV Jacks & Stabilizers AI pick
Chosen by an AI model from its trained knowledge, with its reasoning.
AI pick (line): Lippert JT's Strong Arm Jack Stabilizer
It braces existing scissor or landing jacks against side-to-side and fore-aft sway, which is the most effective upgrade for a trailer that shakes when people move inside.
Not for: Motorhome owners and anyone whose trailer lacks frame-mounted jacks it can attach to.
AI picks by need
For powered tongue jack for travel trailers
Lippert Power Tongue Jack (line)
An electric A-frame jack removes the hand-cranking from hitching and unhitching and usually includes a work light.
Not for: Fifth-wheel owners and trailers without 12V wiring near the tongue.
For replacement scissor stabilizer jacks
Ultra-Fab Products (brand)
An established maker of bolt-on and weld-on scissor stabilizer jacks used as factory and replacement parts.
Not for: Owners who need to lift or level the trailer, which scissor stabilizers are not built to do.
What the AI looks for in RV Jacks & Stabilizers
- Stabilize versus lift
- Stabilizer jacks are only for taking up motion after the RV is leveled and they should never carry the weight of the coach. Using stabilizers to lift or level bends the jacks and can damage the frame.
- Jack type
- Tongue and landing jacks are rated to lift. Scissor and stack jacks are rated only to steady. Buying the wrong type for the job leads to failures or bent jacks.
- Mounting fit
- For replacement jacks, match the frame width, bolt-on or weld-on mounting, and extended and retracted heights. A jack that does not reach the ground at full extension, or hangs too low at retraction, is useless.
- Footing
- Put pads or blocks under jack feet on soft ground. Feet sink into dirt and gravel, and the stabilization is lost.
- Drive compatibility
- Check whether your scissor jacks are cranked by hand or by drill-socket size before buying a socket or adapter. Drive sizes vary between makers.
Brands that matter
- Lippert: Major OEM supplier of tongue jacks, landing gear and stabilizer systems.
- Ultra-Fab Products: Scissor and stabilizer jacks, common as factory equipment.
- BAL: Long-running maker of trailer stabilizing jacks and accessories.
What to avoid
- Leveling the RV with stabilizer jacks.
- Overtightening stabilizers until the tires unload.
- Replacement jacks that are bought without measuring the extended and retracted heights.
Questions
Why does my trailer still shake with the stabilizers down?
Scissor jacks mainly resist vertical motion. Adding cross bracing, tire-locking chocks between tandem wheels, and a tight front jack reduces most of the remaining sway.
