Product Details
Lock Right Differential by Powertrax®. Powertrax Lock Right performance lockers straight-line performance is equal to a solid spool axle, yet they automatically unlock during turns. When extreme traction output and high-strength are required, racers, hot-rodders and muscle car owners chose Lock-Right lockers! 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. The whole job can be done in your driveway with common hand tools in a couple of hours. A carrier is not included.
When powering straight ahead, the cross-shaft engages the saddles in the drivers at an angle such that, in addition to rotating the drivers, forces the teeth of the drivers into engagement with the teeth of the respective couplers. The harder the driving torque, the stronger the tooth engagement. When entering a turn, the driver on the outside of the turn advances ahead of the cross shaft so there is no torque or outward force imposed on this driver. The opposing driver remains fully engaged delivering engine power. After about 1° of rotation, the pins in the driver bottom out in the holes of the opposing driver, so it is now restrained from further rotation. Because the coupler is splined to the axle, it continues to rotate ahead of the driver. The positive angle on the coupler and driver teeth then enables the driver to disengage from the coupler with 1/2° of additional rotation. As the vehicle continues through the turn, the driver repeatedly engages and disengages from the coupler, making the aforementioned ratcheting sound. The springs between the two drivers ensure that the driver will reengage with the coupler when the vehicle exits the turn. The cross-shaft contacting the saddles provides the final engagement force, not the springs. In summary, the LOCK-RIGHT Locker offers full wheel differentiation combined with maximum traction.
