      Description

      Made for Daily Driving. The G2 8.5 in. & 8.6 in. Rear Ring Gear and Pinion Kit with 4.56 gear ratio is designed for daily-driven vehicles where noise levels can be an issue. It’s made to OE factory specifications that ensure a perfect fit and easy installation. Additionally, it’s precision-machined and is made to be more durable and less noisy than stock.

      High-Quality Construction. The G2 utilizes advanced manufacturing technology to precision-machine forged 8620 steel. The Ring Gear and Pinion are also heat-treated to improve durability and wear-resistance. Furthermore, the mating surfaces are lapped to smoothen them for reduced friction and road noise.

      Professional Installation Recommended. G2 recommends that the kit is installed by a professional mechanic due to the complex process involved as incorrect installation can result in noise, premature wear, and even failure.

      10-Year Limited Warranty. The 8.5 in. & 8.6 in. Rear Ring Gear and Pinion Kit is warranted to be free of defects in workmanship and materials. Exclusions will apply.

      Application. The G2 8.5 in. & 8.6 in. Rear Ring Gear and Pinion Kit with 4.56 gear ratio is designed to fit 2007 to 2018 GMC Sierra 1500 models.

          Easy to find what i was looking for. Lots of great photos, and even able to match the year, make, model, and color of my truck for great reference to what the product will look like installed on my truck.
