{"product_id":"lock-right-7-5-inch-10-bolt-28-spline-differential-locker","title":"Lock-Right 7.5-Inch 10-Bolt 28-Spline Differential Locker","description":"The Powertrax Lock-Right locker provides an effective solution for upgrading your Ford 7.5-inch 10-bolt differential to gain 100% on-demand traction. By precision-machining the gears to match OEM tooth geometry, this unit offers a robust upgrade that maximizes power transfer and durability compared to standard open differentials.\n\nConstructed from heat-treated alloy steel, this locker is built to withstand significant torque demands, making it suitable for high-performance applications and heavy-duty use. The design relies on precise fits to carrier housing bores, which simplifies installation for experienced technicians by eliminating the need for complex shimming.\n\nCompatibility is strictly limited to 28-spline Ford 7.5-inch open differentials. It is only recommended for gear ratios up to 4.10; gear ratios of 4.56 and numerically higher are not recommended, as they may require excessive material removal from the ring gear teeth. Installation requires mechanical proficiency, and in some applications, clearance of ring gear teeth may be necessary for proper fitment. This unit is compatible with various Ford, Lincoln, Mazda, and Mercury vehicles, including the 1979-2014 Ford Mustang, 1983-2013 Ford Ranger, and 1984-1990 Ford Bronco II, among others.","brand":"Powertrax","offers":[{"title":"Default Title","offer_id":52663320346936,"sku":"00698231806098","price":714.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687527755.jpg?v=1784325921","url":"https:\/\/store.motormia.co\/products\/lock-right-7-5-inch-10-bolt-28-spline-differential-locker","provider":"MOTORMIA","version":"1.0","type":"link"}
