{"product_id":"xp-series-main-bearing-set","title":"XP Series Main Bearing Set","description":"The King MB5568XP XP Series Main Bearings are engineered for the demands of competitive racing, offering advanced metallurgical and geometric technologies to withstand extreme performance loads. Developed specifically for engines utilizing forged steel aftermarket crankshafts and subjected to prolonged high-stress conditions, these bearings are built to exceed conventional limits.\n\nA key innovation in the XP series is the pMax Black™ overlay, a proprietary tri-metal structure that is 24% harder than standard tri-metal race bearings. This enhanced hardness, combined with XP geometric features like Bull's Eye Tolerance for perfect clearance, U-Groove for a greater load surface, and ElliptiX for improved oil ingress, makes these bearings an ideal choice for performance racing applications.\n\nThese main bearings are designed to fit various Honda engines, including the D16A, D16Z, H22A4, and F23A. The package includes one set of main bearings.","brand":"King","offers":[{"title":"Default Title","offer_id":52686460911928,"sku":"MB5568XP","price":66.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687879032.jpg?v=1784874068","url":"https:\/\/store.motormia.co\/products\/xp-series-main-bearing-set","provider":"MOTORMIA","version":"1.0","type":"link"}
