      Description

      Performance Rear Axle Gear. The Motive Gear 9.50-Inch Rear Axle Ring and Pinion Gear Kit with a 4.88 Gear Ratio is designed to replace the original equipment gears in GM 9.5-inch 12 bolt rear differentials. This gear set optimizes torque delivery and enhances drivetrain strength, essential for reliable power transfer and improved vehicle performance. It is ideal for maintaining or improving the efficiency and durability of your rear axle.

      Precision Machined Components. Manufactured from high-grade 8620 steel, the ring gear and pinion gears undergo rigorous quality control and in-house testing to ensure durability and precise fitment. The components feature a standard rotation pattern and are built to withstand demanding conditions while providing long-lasting performance.

      Installation. Installation requires mechanical knowledge and proper tools. No drilling is necessary as the kit is designed for direct fitment with existing GM 9.5" 12 bolt differentials. Proper setup is critical to ensure accurate gear mesh and optimal operation.

      Warranty. This product includes a one-year or 50,000-mile warranty, providing confidence in reliability and workmanship.

      Application. Specifically fits the 2014 to 2018 GMC Sierra 1500 series, supporting precise gear ratio upgrades without compatibility issues.
