What is the difference between RV stabilizer jacks and leveling jacks?

Stabilizer jacks reduce rocking and side-to-side motion once your RV is parked and level; they are not built to lift the weight of the rig. Leveling jacks (including scissor jacks rated for lifting and powered hydraulic or electric systems) carry load and correct the angle of the coach front-to-back and side-to-side. Most trailers and fifth wheels use a combination: leveling blocks or powered jacks to level, then stabilizers at the corners to lock the rig in place.

What size jack pads do I need under my stabilizer or leveling jacks?

Match the pad footprint to your jack foot and the surface you camp on. For standard scissor stabilizers a 9 to 10 inch square pad is typical, while fifth wheel landing gear and hydraulic leveling feet usually call for 12 inch or larger pads to spread the load on soft ground, gravel, or asphalt in hot weather. Check the load rating printed on the pad against the weight your jack will carry, and always confirm the jack foot sits fully on the pad before extending.

Will these stabilizers work on a fifth wheel, travel trailer, or motorhome?

This collection covers all three. Scissor-style stabilizers fit most travel trailers and smaller fifth wheels with frame-mounted brackets, dedicated 5th wheel king pin and tripod stabilizers reduce chucking at the hitch, and slide-out stabilizers and jack pads work on motorhomes with hydraulic or electric leveling. Confirm your frame height, mounting pattern, and jack foot size before ordering. For related setup gear, see our RV patio mats and RV electronics for leveling sensors and monitors.

Do wheel chocks replace stabilizer jacks?

No. Wheel chocks stop the trailer from rolling and tandem-axle X-style chocks wedge between the tires to reduce fore-aft movement, but they do not stabilize the corners of the rig. Use chocks first for safety any time the trailer is unhitched, then deploy your stabilizer jacks to control rocking. For seasonal storage, pair chocks with our RV winterizing kits to protect the plumbing system while the rig sits.

How much weight can a stabilizer jack actually hold?

Most scissor stabilizers are rated for 5,000 to 7,500 pounds of static support, but that rating is for holding position, not lifting. Never use a stabilizer to raise the trailer off the ground or to change a tire. If you need lifting capacity, look at scissor leveling jacks (rated 5,000+ lbs for lift) or a dedicated trailer jack. The product spec sheet on each listing shows the static and dynamic ratings.

Does this collection ship free?

Yes. Stabilizers, jacks, pads, and chocks in this collection ship free on orders over $100 within the continental US. Larger powered leveling systems may ship via standard freight; the product page lists the shipping method before checkout. Questions on fitment or freight? Text or call our team at 817-984-1852.
