New Lock-RIght Performance Locker Kit.

When operating off-road, the LOCK-RIGHT will always send the engine power to the wheels that need it most. For example, if you are rock crawling and one wheel is in the air (complete loss of traction), the wheel on the ground will receive the engine power and keep you going. Whether it be snow, sand, mud, ice, etc... the LOCK-RIGHT will give you the traction you need.
