On connecting rod bearings, the surface layer is thinner to better withstand fatigue.\u003c\/p\u003e\u003cp\u003eRace Series bearings have increased crush and a slightly more eccentric shape than standard bearings—two details designed to ensure the bearing does not move and remains well-lubricated when the block and connecting rods deform under load.\u003c\/p\u003e\u003cp\u003eIn standard size, ACL specifies them for a connecting rod journal of 47.758 to 47.778 mm, with a bearing width of 17.4 mm. For that diameter, they recommend an oil clearance of approximately 0.051 to 0.061 mm, measured with a micrometer and bore gauge. If the crankshaft has been reground, the measurement changes.\u003c\/p\u003e\u003cp\u003eThey do not have the silver-tin flash plating of standard bearings, so their dark color—ranging from brown to black and bluish—is the factory finish and does not indicate any defect. ACL advises against polishing the bearing surface to adjust clearance; if more clearance is needed, they should be paired with the HX version, which provides an additional 0.025 mm of clearance.\u003c\/p\u003e\u003cp\u003eBefore ordering, please confirm your crankshaft measurement (standard or reground); if you have any questions, contact us with your engine code.\u003c\/p\u003e","brand":"ACL","offers":[{"title":"Default Title","offer_id":50813151281486,"sku":"4B5562H-STD","price":97.6,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0816\/7329\/0062\/files\/aa79c1c2cf76a19f3bab6d18ebb68dbc.jpg?v=1735904239","url":"https:\/\/driftandgrip.com\/en\/products\/acl-trimetal-reinforced-rod-bearings-audi-s3-tts-2-0l-tfsi-ea888","provider":"Drift \u0026 Grip","version":"1.0","type":"link"}
