They are the standard choice when opening an engine for a build.\u003c\/p\u003e\u003cp\u003eInternally, they feature three layers on a high-strength steel backing: a copper-lead-tin lining, a thin nickel barrier, and a lead-tin-copper overlay, which is the surface that works against the crankshaft. In the connecting rod bearings, the surface layer is thinner to better withstand fatigue.\u003c\/p\u003e\u003cp\u003eThe Race Series have more crush and a slightly more eccentric shape than standard bearings, two details designed to keep the bearing from moving and to ensure proper lubrication when the block and connecting rod deform under load.\u003c\/p\u003e\u003cp\u003eIn standard size, ACL specifies them for a crankpin diameter of 51.990 to 52.000 mm, with a bearing width of 20.12 mm. For that diameter, they recommend an oil clearance of about 0.055 to 0.065 mm, measured with a micrometer and bore gauge. If the crankshaft is reground, the measurement changes.\u003c\/p\u003e\u003cp\u003eThey do not have the silver tin final plating of standard bearings, so their dark color—ranging from brown and black to bluish—is the factory finish and does not indicate any defect. ACL advises against polishing the bearing surface to adjust clearance; if more is needed, they are combined with the HX version, which provides an additional 0.025 mm of clearance.\u003c\/p\u003e\u003cp\u003eIf the crankshaft has been reground or if you are unsure of the required size, please write to us with your engine code before ordering.\u003c\/p\u003e","brand":"ACL","offers":[{"title":"Default Title","offer_id":50813078307150,"sku":"ACL-4B2166H\/18","price":73.19,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0816\/7329\/0062\/files\/acl-rod-bearings_3f7f30b3-c1a1-4962-a2ef-a08e26f436c9.jpg?v=1735903634","url":"https:\/\/driftandgrip.com\/en\/products\/acl-trimetal-reinforced-rod-bearings-ford-2-0l-cosworth","provider":"Drift \u0026 Grip","version":"1.0","type":"link"}
