Revolution Gear & Axle GM 10-Bolt 8.5in/8.6in 4.10 Ratio Face Hobbed Ring & Pinion Set

Upgrade the drivetrain performance of your compatible GM 10-bolt rear axle with the Revolution Gear & Axle GM 10-Bolt 8.5-inch/8.6-inch 4.10 Ratio Face-Hobbed Ring and Pinion Set. Designed for automotive differential applications, this matched ring and pinion gear set uses a 4.10:1 gear ratio to provide a practical balance of acceleration, cruising performance, and drivetrain response. The set is identified by part number rgaGM10-410DC and is engineered for use with GM 10-bolt 8.5-inch and 8.6-inch axle assemblies where the application and differential configuration are properly matched.
Revolution Gear & Axle manufactures this ring and pinion set using face-hobbing technology, a gear-cutting process intended to support accurate tooth engagement and consistent operation when installed with correct setup procedures. Proper installation requires careful measurement and adjustment of backlash, pinion depth, bearing preload, and gear contact pattern. Professional installation is recommended, particularly for performance, restoration, and gear-ratio replacement projects where precise differential setup is essential for long service life and quiet operation.
This ring and pinion set is a direct replacement-style drivetrain component for rebuilding or re-gearing a compatible axle. Verify axle identification, spline configuration, carrier requirements, and existing differential components before ordering. The 4.10 ratio may require a compatible carrier or related installation hardware depending on the original axle ratio and application. Follow the manufacturer’s installation recommendations and use the appropriate differential lubricant after assembly. Revolution Gear & Axle part number rgaGM10-410DC provides a purpose-built solution for GM 10-bolt 8.5-inch/8.6-inch differential applications requiring a 4.10 ring and pinion ratio.
