Description

Powertrax Lock-Right performance lockers provide brute force traction equal to a solid spool axle, yet automatically unlock during turns. Best suited for extreme off-road to severe on-road use, Powertrax lockers replace the spider gears in your differential carrier without affecting your ring and pinion settings. A carrier is not included. This model is for GM 8.5" (10 Bolt) differentials with 30 spline axles and an open differential.
