Differential Bearing Kit

The USA Standard Gear differential bearing and seal kit (ZBKGM8.6-B) is engineered to provide the critical components needed for a professional differential rebuild on select GM 8.6" axles. Unlike a master install kit, this package omits shims, making it perfect for applications where existing shims are in good condition and can be reused. This comprehensive kit features premium Koyo bearings and races, known for their durability and performance. It also includes essential small parts required for installation, such as a pinion seal, pinion nut, crush sleeve, gear marking compound, and a new gasket or RTV silicone. The inclusion of carrier bearings and races makes it a robust solution for restoring smooth and reliable operation to your vehicle's rear differential. The USA Standard Gear differential bearing and seal kit is backed by a one-year warranty against manufacturer defects, offering peace of mind for your investment. This kit is specifically designed to fit 2009 and newer GM 8.6" rear differentials. Always verify fitment for your specific vehicle application.
