{"product_id":"xp-series-main-bearings","title":"XP-Series Main Bearings","description":"The King MB5227XP XP-Series Main Bearings are engineered for enhanced engine performance and durability. These bearings utilize King's proprietary Alecular Bearing Material, a specialized alloy that provides superior embedability compared to traditional tri-metal constructions. The Alecular material is applied as a single deep layer (.012\" - .015\") onto a robust steel backing.\n\nKing Engine Bearings are manufactured with exceptionally tight wall thickness tolerances, held to +\/- .0001\", which is significantly tighter than industry standards. This precision manufacturing also extends to the bearing flange length, a technology pioneered by King, which can aid in managing borderline crankshaft endplay situations without requiring additional machining. The XP-Series also features a narrowed design for large radii crankshafts, enlarged, chamfered oil holes, and options for full, 3\/4 in., or 1\/2 in. grooving for optimal oil flow.\n\nThese main bearings are designed as a Standard Replacement grade type with an inside diameter of 57.0mm. They come with a 1 Year Manufacturer Warranty.","brand":"King","offers":[{"title":"Default Title","offer_id":52686468514104,"sku":"MB5227XP","price":105.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687879109.jpg?v=1784874145","url":"https:\/\/store.motormia.co\/products\/xp-series-main-bearings","provider":"MOTORMIA","version":"1.0","type":"link"}
