{"product_id":"race-series-engine-bearings","title":"Race Series Engine Bearings","description":"These bearings are constructed with a unique Tri-metal material and feature hardened steel backs for superior support and housing retention. Key design elements include a high-strength overlay plate for increased fatigue resistance, elimination of flash plating to improve heat transfer and grip, and increased eccentricity to manage bore distortion and aid in hydrodynamic oil film formation.\n\nFurther enhancing their performance capabilities, these bearings include a \"3\/4 grooved main bearing\" design to optimize load area and oil flow to the connecting rod bearings. They also feature tight wall tolerances for consistent clearances and enlarged inner diameter chamfers where necessary to accommodate larger fillet radii on performance crankshafts, simplifying installation. The \"Identical Halves\" design ensures symmetry and consistent performance.\n\nSpecific technical details include standard oil clearance, available sizes of STD, .025, and .25, and material composition of Tri-metal with hardened steel backs. Critical dimensions such as minimum and maximum standard shaft size, minimum and maximum standard tunnel size, maximum wall at the crown, and maximum overall length are precisely engineered. These bearings are listed for fitment in Hyundai Genesis (2009-2016), Hyundai Sonata (2005-2018), and Kia Optima (2001-2018) models, specifically those equipped with the G4KF 2.0T engine.\n\nA Proposition 65 warning is included, stating \"⚠ WARNING: Cancer and Reproductive Harm\" with a link to P65Warnings.ca.gov, as required for products sold in California.","brand":"ACL","offers":[{"title":"Default Title","offer_id":52686752481592,"sku":"ACL4B1293H-STD","price":98.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660671250.jpg?v=1784876325","url":"https:\/\/store.motormia.co\/products\/race-series-engine-bearings","provider":"MOTORMIA","version":"1.0","type":"link"}
