Tired of the one wheel spin when you own a Willys? Powertrax® Lock-Right performance lockers’ straight-line performance is equal to a solid spool axle, yet they automatically unlock during turns. This locker is specifically for the 10 spline Dana 44 found in 1946-1964 Willys and Jeep vehicles. 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. See attached instructions.
