Upgrade the drivetrain of your GM 12-bolt truck with the Yukon Gear and Axle YG GM12T-411 ring and pinion gear set. Designed for an 8.875-inch GM 12-bolt differential, this gear set features a 4.11:1 ratio and a 30-spline pinion for dependable power transfer and improved gearing performance. The kit is engineered for applications using a 4-series carrier and is suited to differential rebuilds, axle upgrades, and replacement installations where precise fit and reliable operation are required.
The Yukon Gear and Axle YG GM12T-411 is manufactured to support consistent engagement between the ring and pinion gears, helping deliver smooth operation under demanding driving conditions. Its 4.11 ratio can provide stronger low-speed pulling performance and responsive acceleration compared with taller gearing, making it a practical choice for trucks used for towing, hauling, off-road driving, or performance-oriented applications. Proper setup with the correct installation tools, bearings, shims, marking compound, and manufacturer-recommended gear oil is essential for achieving the intended service life.
This ring and pinion kit is intended for GM 12-bolt truck differentials with the specified carrier and pinion spline configuration. Confirm axle housing, carrier series, spline count, ratio requirements, and differential compatibility before ordering. The kit is not air restricted and does not require truck freight shipping, providing a straightforward solution for professional installers and experienced enthusiasts completing a complete gear replacement or differential rebuild.
