{"product_id":"race-series-main-bearing-set","title":"Race Series Main Bearing Set","description":"Their design incorporates a unique combination of metallurgy and engineering to deliver exceptional durability and performance.\n\nKey features include a high-strength overlay plate with reduced thickness for enhanced fatigue properties and hardened steel backs on all rod bearings to improve lining support and bearing retention. These bearings are designed with increased crush for superior retention and the elimination of flash plating on the back to optimize heat transfer and grip between the bearing and its housing. Furthermore, increased eccentricity helps compensate for bore distortion at high RPMs and aids in the formation of hydrodynamic oil films.\n\nSpecifically designed for Subaru EJ-Series Engines requiring a #5 thrust bearing, these main bearings are suitable for 2002-2014 WRX, 2004-2021 STI, 1992-2017 Impreza, and 1989-2020 Legacy models. They feature 3\/4 grooved main bearings to optimize load-carrying surface area and oil flow to the conrod bearings, along with tight, consistent wall tolerances for precise clearances and enlarged ID chamfers to accommodate large fillet radius on performance crankshafts.","brand":"ACL","offers":[{"title":"Default Title","offer_id":52686752776504,"sku":"5M8309H","price":87.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660178642.webp?v=1784876327","url":"https:\/\/store.motormia.co\/products\/race-series-main-bearing-set","provider":"MOTORMIA","version":"1.0","type":"link"}
