Revolution Gear & Axle GM 14-Bolt 10.5in Rear Axle 5.38 Ratio Thick Ring & Pinion Set

Upgrade the drivetrain performance of your GM 14-bolt 10.5-inch rear axle with the Revolution Gear & Axle rgaGM10.5-538T ring and pinion set. Designed with a 5.38:1 gear ratio and a thick ring gear configuration, this set is well suited for off-road vehicles, heavy-duty applications, and builds requiring improved low-speed torque and optimized gearing for larger tires.

This ring and pinion set is engineered for compatibility with GM 14-bolt 10.5-inch rear axle assemblies, providing a purpose-built solution for replacing worn gears or completing a performance-oriented axle upgrade. Proper setup with the correct installation tools, bearing kit, shims, and manufacturer-recommended gear oil is essential for reliable operation.

Revolution Gear & Axle manufactures drivetrain components for demanding automotive applications, and this set is built to support the strength and durability expected from a heavy-duty rear axle. The thick ring gear design provides the required configuration for applicable 5.38-ratio installations. Verify axle compatibility, carrier requirements, spline specifications, and application details before ordering. Professional installation and precise gear pattern setup are recommended to help ensure quiet operation, proper break-in, and long service life.
