Description

The USA Standard Gear ZA K630848 rear axle kit is engineered for GM 8.2-inch differentials, offering a direct-fit solution for replacement and repair needs. This kit is specifically designed with 28 splines and a precise length of 29.825 inches, ensuring compatibility with compatible axle assemblies. The 6-lug configuration makes it suitable for a range of applications. This comprehensive kit includes all the necessary components for a complete axle replacement. You will receive the axle shaft itself, a tapered axle bearing for smooth rotation, a spacer for proper positioning, a seal to prevent lubricant leakage, and studs with lug nuts for secure wheel mounting. These parts are manufactured to meet or exceed Original Equipment (OE) quality standards. Highlighting advanced heat-treating processes, the axle shafts in this kit are built for enhanced strength and durability, offering a longer service life under demanding conditions. The USA Standard Gear brand is known for producing reliable drivetrain components, and this axle kit exemplifies that commitment to quality and performance.
