Powertrax 1940-LR Lock-Right locker for the GM 10-bolt (8.2″ with any gear ratio and 28-spline shafts) is easily installed in existing case assemblies without any special tools or setup equipment. The Lock-Right locker has been extensively used in extreme off-road applications around the world demanding 100% traction output and high-strength. The Lock-Right locker eliminates wheel spin-up and therefore all associated driveline stress is eliminated, which in effect strengthens the differential case and other driveline components.
