This curved leveler includes an interlocking chock to make sure that it stays in place without accidentally slipping out. When used together, they can give your trailer up to 4-1/2" of lift to quickly and easily correct side-to-side tilting.
This roll-on trailer jack makes it easy to change tires on a tandem axle trailer. No need to unload the trailer or fiddle with annoying scissor jacks. We love that you can just ride on, changea tire, and ride away.
