LockRight Posi

Lock-Right is a revolutionary design that replaces your differential's existing spider gears with a coupler gear set that dramatically increases traction. With a typical spider gear differential, the wheel with the least amount of traction usually gets full power - not good when your truck's buried in mud. With Lock-Right, power is sent to the wheel with the most traction, allowing you to power out of any situation. And installation is a snap. It takes about an hour and no special tools or set-up is required because the ring and pinion gears are unaffected. Stop spinning your wheels.
