The comprehensive contents include carrier bearings and races, pinion bearings and races, a pilot bearing, a pinion seal, a complete shim kit for precise gear setup, ring gear bolts, a pinion nut, and a crush sleeve eliminator for optimal pinion depth. Further enhancing its utility, the ZK F9-A kit also includes thread locker to secure critical fasteners, marking compound with a brush for accurate gear pattern analysis, and a gasket for a reliable seal. This ensures that all necessary hardware is on hand for a professional and lasting differential rebuild. This master overhaul kit is compatible with various Ford Mustang models, including the 1965-1966, 1967-1970, 1971-1973, 1979-1993 (Fox Body), and 1994-2004 (SN95) generations, provided they feature the Ford 9-inch differential with the LM102910 carrier race and 28 spline.
