{"product_id":"performance-main-engine-bearings","title":"Performance Main Engine Bearings","description":"The ACL Race Series Main Bearings (5M1959H) are engineered for high-performance applications, offering superior durability and reliability.\n\nConstructed from a high-strength trimetal alloy with a reduced thickness overlay plate, these bearings provide improved fatigue properties. They feature hardened steel backs for enhanced support and retention, and an increased crush design for a more secure fit within the housing. The elimination of flash plating on the back improves heat transfer, maximizing the grip between the bearing and its housing.\n\nThe 3\/4 grooved main bearings are optimized to enhance load-carrying capacity and oil flow to the connecting rod bearings, ensuring consistent lubrication. Tight wall tolerances are maintained to help achieve precise clearances.\n\nKey features include enlarged ID chamfers on bearing edges to accommodate large fillet radii on performance crankshafts. These 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.","brand":"ACL","offers":[{"title":"Default Title","offer_id":52686752284984,"sku":"5M1959H-4B1925H","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661654785.webp?v=1784876322","url":"https:\/\/store.motormia.co\/products\/performance-main-engine-bearings","provider":"MOTORMIA","version":"1.0","type":"link"}
