These Powertrax no-slip traction systems are the latest design in traction-adding differential technology. They combine the smooth operation of a limited-slip differential with the traction performance of a locking differential. A precise synchronization mechanism eliminates the ratcheting sounds typical of other locking differentials. Special gear and spring designs reduce the backlash and, therefore, the driveline windup. Only ultra-strength material that is 67 percent stronger than titanium is used. Installation is simple because no ring and pinion setup is required. In addition, no special tools or oils are needed. Step-by-step, model-specific instructions are provided with every kit.
