Description
Rear Axle Gear Kit. The Motive Gear 9.50-Inch Rear Axle Ring and Pinion Gear Kit with a 4.88 gear ratio is designed as a direct replacement for the original equipment ring and pinion gears in GM 9.5-inch differentials. This gear set optimizes driveline performance by adjusting the final drive ratio, impacting acceleration and torque delivery. It ensures proper fitment and durability for enhanced drivetrain operation.
Construction and Appearance. Manufactured from high-quality 8620 steel, these ring gears are engineered for superior strength and longevity. Gear teeth are precisely machined and subjected to strict quality control standards, providing a durable component with standard gear rotation suitable for heavy-duty use.
Installation. Installation requires an experienced technician familiar with differential setups. This kit does not require any drilling but must be installed with a compatible carrier that supports the specified gear ratio. Proper setup is essential to ensure correct gear mesh and optimal performance without modifications to the axle housing.
Warranty. This product includes a 1-year or 50,000-mile warranty, offering assurance of quality and reliability.
