Standard 3\/8\" 1350 U bolts were found to be prone to cycle failure when cycle tested at high torque levels. One piece U-bolt allowed release of joint lock from differential companion flange. Surrounding the joint cup provides a full 360 degree support for up to 500 lbs of torque. This 2nd generation U-bolt (cap) kit features position indexing bubble studs in the rear flange bolt holes. The straps are made of pre-heat treated chrome molybdenum steel, the studs are 150K material and are rolled threaded. 12 point reduction double hex nuts are sold as a set. Fits current Mark Williams forged billet rear pinion yoke. \u003cbr\u003e\u003cbr\u003e \u003cbr\u003eManufacturer: ‎Mark Williams Enterprises\u003cbr\u003ePart number: ‎39112\u003cbr\u003eItem weight: ‎194 g\u003cbr\u003eProduct size: ‎7.62 x 7.62 x 1.27 cm; 194 g\u003cbr\u003e br\u0026gt;Discontinued by manufacturer: ‎No\u003cbr\u003eMaterial: ‎4140 chrome molybdenum steel. \u003cbr\u003eBatteries included: ‎No\u003cbr\u003eBatteries used: ‎No\u003cbr\u003eProduct dimensions (Length x Width x Height): 7.6 x 7.6 x 1.3 cm","brand":"Auto Parts Tokyo","offers":[{"title":"Default Title","offer_id":47687456915776,"sku":"B002WBIGQK","price":234.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0853\/2584\/0704\/products\/513bUAN-9eL._AC_US1200.jpg?v=1705555795","url":"https:\/\/megashopjapan.com\/products\/mark-williams-enterprises-39112-2nd-generation-u-bolt-kit","provider":"Mega Shop Japan","version":"1.0","type":"link"}
