    For Great Performance. With the name EXCEL, you know you're in good hands. The EXCEL from Richmond 8.5 in. &  8.6 in. Rear Ring Gear and Pinion Kit - 4.56 Gears give your Sierra 1500 more performance when you use it in place of the factory's rear ring and pinion duo.

    4.56 Gear Ratio. Count on this EXCEL from Richmond Gear and Pinion Set to maintain top performance for your rig. Perhaps best yet, the faster acceleration is durable without running your wallet dry at the gas pump.

    Heat-Treated Steel. Richmond Gear makes this 10-bolt Rear Ring and Pinion Set from heat-treated 8620 steel for superior strength and reliability. Depending on your vehicle, the ring gear diameter is 8.5 in. or 8.625 in.
