      Description

      Heavy-Duty Gear Upgrade. The Motive Gear 10.50-Inch Rear Axle Thick Ring and Pinion Gear Kit is designed for high-torque applications in your Sierra 2500 HD. With a 4.88 gear ratio and a thick gear design, this kit enhances low-end power and drivetrain durability—perfect for towing, off-roading, or performance upgrades.

      Construction and Appearance. Built for strength and precision, this ring and pinion set is engineered to fit GM 10.5-inch rear differentials. The thick gear design is ideal for use with aftermarket carriers or when upgrading from a numerically lower gear ratio, ensuring greater resistance to stress and wear in demanding conditions.

      Installation. Installation is rated as hard and should be performed by experienced mechanics or drivetrain specialists. Proper setup requires specific tools and procedures, including gear pattern checks and preload adjustments.

      Warranty. This product includes a one-year or 50,000-mile warranty against defects in materials and workmanship.

      Application. This Motive Gear 10.50-Inch Rear Axle Thick Ring and Pinion Gear Kit fits 2007 to 2018 GMC Sierra 2500 HD models equipped with a GM 10.5-inch rear differential.
