For vehicles that are driven daily, the Powertrax® No-Slip Traction System is the latest design in quiet traction-adding differential technology. It combines the automatic street-friendly smooth operation of a limited-slip differential with the traction performance of a locking differential.
A patented, precise synchronization mechanism eliminates the ratcheting sounds typical of other automatic locking differentials. Special gear and spring designs reduce the backlash and, therefore, driveline windup. Only 9310 ultra-strength material is used, which is stronger than titanium.
Installation is simple because no ring and pinion set-up is required. In addition, no special tools or oils are needed. Step by step instructions are provided with every kit.
