Product Description

The Revolution Gear & Axle 35-2021 Master Install Kit is tailored for the GM 8.5" 10-Bolt rear differential - commonly found in many GM trucks and SUVs. Whether you're replacing a worn ring & pinion set, upgrading for larger tires, or doing a full differential rebuild, this kit gives you all the major components needed to complete the job.

Premium hardware such as Timken bearings, quality seals and hardware included streamlines the rebuild process, reducing the risk of missing parts or compatibility issues. With this kit, you gain the convenience of a package solution rather than sourcing multiple components separately.

Prior to installation, ensure you verify your vehicle's axle housing (8.5" 10-Bolt), spline count, gear ratio and any trim-specific variations. Proper measurement of backlash, gear pattern and preload is still required - this kit supplies the hardware, not the adjustment procedure.
