Description

The USA Standard Gear ZA K630837 is a rear axle kit engineered for GM 9.5 inch differentials, offering a robust solution for repair or upgrade needs. This comprehensive kit includes all essential components for a complete axle replacement: the axle shaft itself, a new wheel bearing, a differential cover gasket, a seal, studs, and lug nuts. It is specifically designed for rear, semi-float axle applications and features a 33-spline count, an 8-lug bolt pattern, and a precise length of 33.3125 inches. These specifications ensure an exact fit and optimal performance for compatible vehicles. Application is key for this axle kit. It is designed to fit various Chevrolet Silverado 1500 HD Classic, 1500 HD, and 2500 models from 1999 to 2007, as well as Chevrolet Suburban 2500 models from 2000 to 2007. It also fits compatible GMC Sierra 1500 HD Classic, 1500 HD, and 2500 models, and GMC Yukon XL 2500 models, all rear applications, provided they are equipped with a 14-bolt differential cover. Both 4WD and RWD drivetrains are supported for most listed applications.
