      Description

      Increases Acceleration and Torque. The 5.13:1 gear ratio of the G2 8.5 in. & 8.6 in. Rear Ring Gear and Pinion Kit dramatically improves the torque transferred to your wheels. This makes hauling and towing easier, especially on inclined or rough types of terrain. Acceleration is also significantly increased for a more responsive driving performance.

      Manufactured to Meet Performance Needs. The G2’s Performance Series 8.5 in. & 8.6 in. Rear Ring Gear and Pinion Kit is made from hardened 8620 steel for added reliability. The strong alloy also allows it to handle the high torque being produced by the truck’s engine. Moreover, behind the seemingly simple design of the gear and pinion is a state of the art manufacturing process. This enables the part’s design to meet exact tolerances and specification for seamless mating of gears.

      Requires Professional Mechanic for Installation. Replacing the rear ring gear and pinion is a complicated task that involves plenty of moving transmission parts and even specialty tools. Installation is best left to professionals.

      Covered with 10 Years Limited G2 Warranty. G2 warrants their gear and pinions from manufacturing and material defects for the stated time period. Read G2’s warranty policies for additional details.

      Application. The G2 8.5 in. & 8.6 in. Rear Ring Gear and Pinion Kit with 5.13 Gears will fit 1999-2018 GMC Sierra 1500 models.

            Word on the Trail

            My favorite part is that you can put in your trucks make and model, and only shop parts that will fit that truck. Makes life so much easier.
