{"product_id":"race-main-engine-bearings","title":"Race Main Engine Bearings","description":"The ACL Race Series Main Bearings are constructed with a unique combination of design, metallurgy, and engineering to meet the demands of high-performance engines. These Trimetal bearings are built to withstand higher RPM conditions, featuring a high-strength overlay plate with reduced thickness for enhanced fatigue properties. The hardened steel backs on all rod bearings provide improved support for the bearing lining and assist with retention within the housing.\n\nKey design elements include increased crush for better bearing retention and the elimination of flash plating on the back of the bearings to improve heat transfer and ensure a secure grip between the bearing and its housing. Increased eccentricity is incorporated to compensate for bore distortion at high RPMs and to aid in the formation of hydrodynamic oil films. The 3\/4 grooved Main Bearings are designed to optimize load-carrying surface area and oil flow to the connecting rod bearings, while tight and consistent wall tolerances help maintain precise clearances. Enlarged ID chamfers on bearing edges accommodate large fillet radii on performance crankshafts.\n\nThese main bearings are specifically designed for Honda\/Acura B18C1 and B18C5 engines, including the 1994-2001 Acura Integra GS-R and the 2000-2001 Acura Integra Type-R. The product includes one complete set of main bearings and comes with a Manufacturer Standard Warranty.","brand":"ACL","offers":[{"title":"Default Title","offer_id":52686753431864,"sku":"5M1959H","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660671280.webp?v=1784876335","url":"https:\/\/store.motormia.co\/products\/race-main-engine-bearings","provider":"MOTORMIA","version":"1.0","type":"link"}
