Upgrade or restore the drivetrain performance of a compatible GM 7.75-inch rear axle with the Motive Gear GM9-370 Ring and Pinion Kit.

The 3.70 ratio provides a balanced gearing choice for a range of street, utility, and performance applications. Replacing worn, damaged, or improperly matched differential gears can help restore smooth power delivery and support proper axle operation when the gear set is installed and adjusted according to the vehicle manufacturer’s specifications. Proper setup is essential and typically includes checking gear contact pattern, backlash, bearing preload, and other related drivetrain clearances.
Motive Gear is recognized for producing replacement drivetrain components for a broad range of automotive applications. The GM9-370 kit is identified by its 3.70 ratio, GM 7.75-inch axle application, and 27-spline pinion configuration. Always verify axle compatibility, spline count, ratio requirements, and installation specifications before ordering. Professional installation by a qualified drivetrain technician is recommended because ring and pinion service requires specialized tools, accurate measurements, and careful adjustment for correct operation and long-term durability.
