Description
Precision Gear Replacement. The Motive Gear 9.50-Inch Rear Axle Ring and Pinion Gear Kit with 3.73 Gear Ratio is engineered to replace the original equipment in your vehicle’s rear differential, ensuring optimal power transfer and drivetrain performance. It is designed to restore or upgrade gear ratios for improved acceleration, towing capacity, or fuel efficiency in compatible vehicles. Correct ring and pinion ratios are vital for maintaining drivetrain harmony and vehicle longevity.
Construction and Appearance. This gear kit features ring gears forged from high-grade 8620 steel, renowned for strength and durability under heavy loads. The ring gear has a standard tooth count of 41, paired with a pinion gear comprising 11 teeth, a robust 1.875-inch shaft diameter, and a 32 spline count. Each component undergoes rigorous quality control in a dedicated in-house laboratory to ensure precision manufacturing and a surface finish optimized for durability and noise reduction.
Installation. Professional installation is required due to the precision necessary for setting proper backlash and gear pattern. The installation process demands careful attention to torque specifications and differential carrier compatibility, especially noting the requirement for a 3.42 or numerically higher ratio carrier.
Warranty. This product includes a 1-year or 50,000-mile warranty, providing peace of mind regarding durability and performance. Application. It specifically fits 2014 to 2018 Sierra 1500 models and is compatible with other GM 9.5″ 12 bolt applications requiring a 3.73 gear ratio, excluding those with the Max Trailering Package on 5.3L engines.
