Description

The USA Standard Gear Master Overhaul Kit (ZK F9-A-SPC) is engineered for the Ford 9-inch differential, specifically for applications utilizing the LM102910 carrier race and a solid spacer. This all-in-one kit simplifies the differential rebuild process by consolidating all essential components into a single part number, offering a cost-effective and time-saving solution for both general installers and DIY customers. Also provided are a pilot bearing, pinion seal, a complete shim kit for precise setup, ring gear bolts, pinion nut, a crush sleeve eliminator for added strength, thread locker, and marking compound with a brush. A gasket is also included to ensure a proper seal during installation. The brand offers a wide array of tailor-made kits to meet specific installation needs, making them a trusted choice for differential work. The ZK F9-A-SPC kit is backed by a 1-year limited warranty against manufacturer defects.
