Product Description

The Ford Racing M-4210-A Ring & Pinion Installation Kit is an essential component for anyone performing a gear replacement or ratio change on a Ford 8.8" rear axle. Designed to support re-installations without replacing the differential bearings - assuming bearings remain in good condition - the kit supplies all the necessary hardware and precision-fit components to ensure correct gear mesh, preload, and reliable sealing. This makes it ideal for restoration, rebuilds, or performance upgrades where bearings are still serviceable.

Using OEM-grade shims, crush sleeve, seal, and ring gear bolts ensures dependable fitment, consistent preload settings, and long-term reliability. Because the kit is engineered specifically for 8.8" axle housings, installers benefit from a straightforward install process - as long as axle housing, bearings, and other components are verified serviceable. For enthusiasts, modifiers, or restorers working on eligible Ford rear ends, the M-4210-A kit offers a quality, dependable foundation for any ring-and-pinion service or upgrade.
