Description

The USA Standard Gear ZK F8.8 Master Overhaul Kit provides all the necessary bearings, seals, and hardware to properly re-gear or rebuild your Ford 8.8" differential. This kit is particularly useful for Jeep Cherokee XJ owners performing an 8.8" axle swap, ensuring a reliable installation. Included in this master overhaul kit are Koyo carrier bearings and races, Koyo pinion bearings and races, a pinion seal, a complete shim kit, ring gear bolts, a pinion nut, and a crush sleeve. This comprehensive collection of parts ensures you have what you need for a successful differential rebuild. This overhaul kit is specifically designed for Ford 8.8" rear differentials. Its applications include custom Jeep Cherokee XJ builds that utilize the Ford 8.8" axle, as well as factory Ford trucks and SUVs equipped with this popular rear axle. Note that some listings mention specific model years for Ford Mustang (e.g., 2010-2014 for the ZK F8.8-B variant) and other Ford vehicles like the Mazda B4000, B3000, Navajo, and Mercury Mountaineer, indicating a broad compatibility with various Ford 8.8" axle applications.
