Description

The USA Standard Gear rear axle kit provides a robust solution for replacing, repairing, or upgrading axle shafts in vehicles equipped with a Ford 9.75-inch differential. It is specifically designed for 34-spline configurations and includes all necessary parts for a comprehensive installation. The kit is precisely measured at 33.5 inches in length, with a 1.620-inch OD wheel bearing, and is intended for the rear, 5-lug, left-hand side application. Included in the package are the wheel bearing, seal, 14mm studs, and lug nuts, offering a complete set to get your vehicle's axle back in service quickly and reliably. This direct-fit design simplifies the replacement process, ensuring compatibility with the specified differential size. This rear axle kit is compatible with 1997-2003 Ford F-150 models. Please note that this product is subject to California Proposition 65 warnings regarding potential exposure to chemicals, including arsenic, which is known to the state to cause cancer.
