    Richmond Gear 92-0775-2605 Powertrax GMC 10 Bolt Locking Differential
    x
    							                        

    The 7.5 inch Powertrax Traction System is the latest design in traction adding differential technology. It combines 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 design reduce the backlash and therefore driveline windup. An ultra-strength alloy material is used throughout, which is 67% stronger than titanium.

    Installation is simple because no ring and pinion set-up is required. In addition, no special tools or oils are needed (installs in about one hour). Step by step model specific instructions are provided with every kit.

    • Positive traction - full locker
      • Delivers engine power to both wheels when coming off the line
      • Upgrade and improve your times and your vehicles reputation 
    • Smooth quiet operation - fully automatic
    • 7.5 Inch Powertrax Unit
    • Do-it-yourself - installs in about one hour
    • No special tools required
    • Works for both cars and trucks
    • Gives 2-wheel drive trucks the traction power of 4x4's
