Yukon Gear YG GM9.5-410-12B is a 4.11:1 ring-and-pinion gear set for compatible 2014-and-newer GM 9.5-inch rear differentials. Designed for standard-rotation applications, this gear set is intended for axle ratio changes or replacement of worn ring-and-pinion gears in select Cadillac, Chevrolet, and GMC trucks, SUVs, and vans.
The set uses a 33-spline pinion configuration and is designed for compatible GM 9.5-inch rear axle assemblies. A 4.11 ratio can be used when changing differential gearing for vehicle builds involving tire-size changes, towing, performance use, or drivetrain repair where this ratio matches the intended setup.
YG GM9.5-410-12B fits a broad range of late-model GM applications, including Silverado 1500, Sierra 1500, Tahoe, Suburban, Yukon, Escalade, Express, and Savana platforms equipped with the correct 9.5-inch rear differential.
