Power Trax No-Slip Traction Systems

From $1,252.91

The 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. Installation is simple because no ring and pinion setup is required. In addition, no special tools or oils are needed.
