Description

Powertrax Lock-Right and performance lockers' straight-line performance is equal to a solid spool axle, yet they automatically unlock to allow for full differentiation in turns. They also reduce the excessive noise, tire wear, and drivetrain damage associated with other lockers. Powertrax lockers replace the spider gears in your differential carrier without affecting your ring and pinion settings. The whole job can be done in your driveway with common hand tools in a couple of hours. A carrier is not included.
