Description

Powertrax Lock-Right performance lockers provide straight-line performance equal to a solid spool axle while automatically unlocking during turns. Designed for extreme off-road to severe on-road use, these lockers replace the spider gears in your differential carrier without affecting ring and pinion settings. This unit is for GM 8.5" (10 Bolt) with 30 splines and for open differentials.
