The Zumbrota Drivetrain ZA K630225 rear axle kit provides all the necessary components for replacing, repairing, or upgrading your vehicle's axle shafts. Designed for Ford 7.5-inch differentials with 28 splines, this kit ensures your vehicle can get back on the road quickly. This kit is constructed with advanced alloys and utilizes the latest heat-treating technologies to produce a strong and durable axle shaft. It includes a wheel bearing, differential cover gasket, seal, studs, and lug nuts, offering a comprehensive solution for axle replacement or upgrade. The axle itself is specified as 29-5/32 inches long, intended for rear applications on 5-lug vehicles, and operates in a right-hand (RH) configuration. The USA Standard Gear product, which this kit is part of, emphasizes a stronger, more durable axle due to its advanced heat-treating process. This focus on material science and manufacturing ensures reliability and longevity for the component.
