Powertrax Lock-Right Locker
The Powertrax Lock-Right and performance locker's straight-line performance is equal to a solid spool axle, yet they automatically unlock to allow for full differentiation in turns. Powertrax lockers replace the spider gears in your differential carrier without affecting your ring and pinion settings.
Application: 1972-2006 Dana 44 (will not fit Corvette, Viper, Grand Cherokee)
