Description

The Powertrax Lock-Right 1921-LR is a mechanical locker designed for GM 8.5" (10 Bolt) differentials with 30 splines, specifically for open differentials. It replaces the spider gears in the differential carrier to provide straight-line performance similar to a solid spool axle while automatically unlocking during turns. Suitable for extreme off-road to severe on-road use.
