Powertrax® - No-Slip Traction System

Powertrax patented SynTRAC™ synchronization mechanism eliminates the ratcheting sounds typical of other automatic locking differentials. Only the highest quality Zytanium® ultra-strength alloy material is used. The Powertrax No-Slip locker easily installs in to your differential carrier using basic tools and without affecting your ring and pinion settings.

Installation
A key feature of the Powertrax Extreme Traction System is that it installs easily in the existing differential case so there is no need to realign the ring and pinion gears. 2-pinion differentials are the easiest to install and do not require removal of the case. 3-pinion and 4-pinion differentials use split cases, requiring case removal. However, because the case is not replaced, all setup parameters are preserved so the installation is still not difficult. The entire installation can be completed in about an hour with basic tools. No special setup is required. At special events, Powertrax demonstrates the ease of installation by installing the Powertrax Extreme Traction System in prepared vehicles in under 5 minutes.

Limited-slip/posi and centrifugally activated differentials can be as easily upgraded with a Powertrax Extreme Traction System as can open differentials. When upgrading a limited-slip/posi differential, it is only necessary to remove preload springs before removing the spider gears, and to remove the friction plates after removing the side gears. For centrifugally activated differential upgrades, it is necessary to remove the governor counter weight and tumbler assembly before removing the spider gears (GM Gov-Lock). Powertrax provides a special tool with each centrifugally activated differential model that easily facilitates this step.

Operation
The Powertrax Traction Systems are the only differential that offers the maximum traction performance of a locking differential with the smoothness of a limited-slip/posi 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 Powertrax 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 Powertrax System's operation is virtually unnoticeable to the vehicle driver until its extreme traction performance is required.

The Powertrax Traction System incorporates an internal access slot for effectively installing the C-clip without the need for teeth elimination that adversely reduces traction output levels. Overall design results allow the Powertrax Traction System models to withstand over 6,800 ft-lb of torque per axle for very small differential applications (representing 75% more torque capability than the axles themselves), to well over 35,000 ft-lb for large differential applications (representing up to 250% more torque capability than the axles themselves).
