A wheel chock and a frame stabilizer tackle two different kinds of movement. The chock sits at a tire to help prevent the RV or trailer from rolling. Valterra's folding cross-frame stabilizer braces against appropriate frame or bumper points to reduce movement while parked. A stabilizer does not replace a wheel chock, a parking brake or a leveling jack.

Two Valterra components and their jobs

Part Where it works Primary purpose
A10-0908 Against a tire, on a suitable surface Resist wheel movement
020106 Beneath suitable frame or bumper contact points Reduce side-to-side or front-to-back sway

Wheel chock A10-0908

Valterra's red wheel chock has a grooved contact surface and a nylon cord for pulling it away when you're ready to move. Use wheel chocks of an appropriate size and quantity for the RV, wheel and surface. Position them according to the vehicle's parking instructions; do not use a loose stabilizer in their place.

Folding stabilizer 020106: identify the assembly

Valterra specifies the folding unit for 14–28-inch frame clearances. The illustrated manufacturer instructions identify an upper contact rail, adjustable folding legs and feet, foot pins, S-hooks, and a ratchet strap. These are assembly components shown for identification; this page does not claim they are offered as individual replacement parts.

Component What to check when setting up
Upper contact rails Contact the RV's frame or appropriate bumper, never fragile plastic or body panels
Adjustable legs and feet Feet rest flat on firm ground; legs adjust to an appropriate angle
Foot pins and S-hooks Both hooks attach to the foot pins as shown in the factory instructions
Ratchet strap Apply only the recommended firm tension; do not use the assembly to raise the RV

Valterra recommends firm ground and an approximate 45–60-degree leg angle. Once the contact rails touch the frame or bumper, the instructions limit additional ratchet movement to no more than two handle cycles. Over-tightening can damage the stabilizer. The device must not be used as a lifting jack.
