{"product_id":"performance-main-bearings","title":"Performance Main Bearings","description":"The King Engine Bearings MB5259XPC is a set of performance main bearings engineered for Honda A, B, and K Series engines. These bearings utilize King's revolutionary pMaxKote™ technology, a unique polymer coating with ceramic nano-composite particles that functions as a fourth layer to significantly enhance wear resistance. This coating is applied directly over King's pMaxBlack™ overlay during the manufacturing process, increasing hardness without altering the bearing's original precision wall thickness.\n\nThe pMaxKote™ coating provides several key benefits, including superior seizure resistance, cavitation resistance, wear resistance, and enhanced protection against oil starvation. The bearings are constructed from a tri-metal, copper-lead nickel material and feature a grooved upper design with a 1\/2 style groove. They are sold as a set of 5 and are designed for stock crankshaft undersize dimensions.","brand":"King","offers":[{"title":"Default Title","offer_id":52686460977464,"sku":"MB5259XPC","price":70.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687879035.jpg?v=1784874069","url":"https:\/\/store.motormia.co\/products\/performance-main-bearings","provider":"MOTORMIA","version":"1.0","type":"link"}
