Powertrax 1921-LR Lock-Right locker for the GM 10-bolt (8.5″ with any gear ratio and 30-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. Cases that are prone to failure with open or limited-slip differentials become one of the strongest links in the drive train when equipped with a Powertrax Lock-Right locker.
Powertrax 1921-LR is for use on GM 10-bolt (8.5″) axles with any gear ratio with 30-spline shafts.
