Differentials from Unitrax
I could not be more pleased to have Unitrax on board as one of our sponsors. They have been absolutely amazing to work with. Once Devin, at Unitrax, understood how Project Responder would be driven, he came up with the perfect solution for traction and performance. The gear ratio selected was 4.30.
In the front axle, a dana 60, a Powertrax™ No-Slip™ differential was installed. The Powertrax No-Slip Traction System is the only differential that offers the maximum traction performance of a locking differential with the smoothness of a limited-slip/positrack differential. It delivers power to both wheels through intermeshing teeth in such a way that one wheel cannot be powered ahead of the other. A specially contoured saddle ensures direct engagement of the intermeshing teeth.
The No-Slip Traction System features a precision synchronization mechanism that holds the driver and coupler disengaged throughout a turn, so the unit remains quiet and operates smoothly. In addition, the springs mounted in the saddle (that impinge on the pinion cross shaft) and the turning resistance of the synchronization mechanism help damp out backlash effects. As a result, the No-Slip Traction System’s operation is virtually unnoticeable to the vehicle driver until its extreme traction performance is required. In the rear axle, a Sterling 10¼, a Trac-Lok limited slip differential was installed.
