The Powertrax automatically directs power to provide full engine torque to both rear wheels, even if one has zero traction. Unwanted wheel slip is controlled. The transition is quiet and smooth from equal torque distribution at both rear wheels to differential action for making turns. Installation is easy with included step by step instructions. There is usually no need for any adjustments to the ring and pinion (Units are for differentials not equipped with positraction unless specified).
