Known in the industry simply as the \"BOP\" differential for the three brands that used it, this axle appeared under a wide range of nameplates - from the Skylark and Electra to the GTO, 442, and Firebird - making correct identification by physical spec more important than relying on year and model alone.\u003c\/p\u003e\u003cp\u003eThis 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 a proper reassembly. Built with Koyo bearings, it's designed to restore correct bearing preload and gear backlash after wear, a gear ratio swap, or a posi\/locker installation - a common step in classic muscle car restorations and rear-end rebuilds.\u003c\/p\u003e\u003cp\u003eBefore ordering, confirm your differential is the 8.2\" 10-bolt BOP unit by checking cover bolt count and ring gear diameter, since several of these platforms also used other GM rear axle designs depending on trim, engine, and model year. 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 if you're changing ratio. Installation requires full differential disassembly 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=\"Revive your classic muscle car with the Yukon ZK GM8.2BOP overhaul kit, designed for 1964-1972 Buick, Olds, and Pontiac models.\"\u003e\u003cmeta name=\"keywords\" content=\"Yukon differential overhaul kit, GM 8.2 inch 10-bolt kit, Buick Oldsmobile Pontiac parts, classic car rebuild kit, muscle car differential repair, Koyo bearings for GM differential, complete rear differential kit, automotive restoration supplies, differential bearing and seal kit, BOP differential rebuilding solution\"\u003e","brand":"Yukon Gear \u0026 Axle","offers":[{"title":"Default Title","offer_id":53864411660607,"sku":"YUKZK GM8.2BOP","price":191.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/7308\/9343\/files\/b28f5d75b6c903de695d21144b962696.jpg?v=1782577437","url":"https:\/\/wcaperformance.com\/products\/usa-standard-master-overhaul-kit-for-the-8-2in-buick-olds-pontiac-diff","provider":"WCA Performance","version":"1.0","type":"link"}
