- Stop the Rock!: Eliminates front-to-back trailer motion and reduces side-to-side sway so your RV feels steady, safe, and rock-solid—like parking on concrete instead of quicksand. Quick leverage design makes setup simple, no wrestling match required. Includes two tire locking chocks.
- XL Fit, Maximum Grip: Expands from 1.5" to 5.5" to lock tandem-axle trailer or fifth-wheel tires in place, even on uneven ground. Creates a secure foundation for camping comfort.
- Heavy-Duty Steel Muscle: All-steel construction with corrosion-resistant zinc plating. This stabilizer is tough enough for years of road trips and all-weather use. Tire-grabbing teeth bite into tread to prevent slipping, so your trailer stays put instead of shimmying like it’s at a dance party.
- Lockable Security: Accepts a standard padlock (sold separately) to deter theft. Lock it, leave it, and enjoy peace of mind while you’re off adventuring.
- Compact & Convenient: Collapses to just 1.5" for easy storage, expands to 5.5" when you need it most. Backed by Ultra-Fab’s lifetime warranty—because forever is hard to beat.

This is really nice, trailer will not move when this is in place. Easy to put on and take off. Love that you can put a lock on it. Really stops the trailer from rocking. We have a 26 ft trailer. Funny story told husband to remove it a few times before leaving, didn't go behind him to see if he did it when we got ready to do .... the truck would not move. – Shirla Willems
Once set up, these things work great! I notice it the most when I back our camper into the driveway. These hold the camper in position way better than just wheel chocks. It makes disconnecting the camper much easier. – Foshag
Love these wheel chocks. Makes setting my camper a breeze. – Dennis
By far the best wheel chock I've ever used. It takes seconds to set up, it holds the wheels tight and it also help keep the camper from rocking. – Al G.
