This kit is built specifically for 9\" units with LM603011 carrier bearing races - a 3.062\" O.D. bearing case found across a huge range of Ford, Lincoln, and Mercury cars, trucks, and vans built from the late 1950s through the late 1980s.\u003c\/p\u003e\u003cp\u003eBecause the Ford 9\" was factory-installed across so many different platforms - and has been swapped into countless hot rods, muscle cars, and off-road builds outside its original application - correctly identifying your carrier bearing case is more reliable than matching by vehicle alone. This kit bundles everything needed for a full rebuild into one part number: carrier and pinion bearings and races, pinion seal, a complete shim kit, crush sleeve, ring gear bolts, and the thread locker, marking compound, and gasket needed for proper reassembly.\u003c\/p\u003e\u003cp\u003eBuilt with Koyo bearings, it's designed to restore correct bearing preload and gear backlash after wear, a gear ratio change, or a locker\/posi installation. This is a rebuild-support kit rather than a ring-and-pinion set, so it pairs with either your existing gears or a new gear set when changing ratio. Installation involves full disassembly of the differential and proper backlash\/preload setup, so it's best suited for an experienced DIY installer or a differential shop.\u003c\/p\u003e\u003cmeta name=\"description\" content='Upgrade your Ford 9\" differential with Yukon ZK F9-C overhaul kit.
