Stabilizers are a great solution to keep your camper or trailer in place. They fit easily between the wheels, creating a counteracting force and keeping them from shifting. They fit wheels from 3.5 to 12 inches, so work great on small trailers as well as large motorhomes. Made of durable, rust-resistant materials that will stand up to any weather conditions. The convenient design makes it quick and easy to lock or loosen the clamps in position. The kit includes two pairs of stabilizers at once, so you can fix both axles. There is also a handle and adapter for installation.
