In the connecting rod bearings, the overlay is thinner to better withstand fatigue.\u003c\/p\u003e\u003cp\u003eRace Series bearings have more housing interference and a slightly more eccentric shape than standard bearings—two details designed to ensure the bearing does not move and remains well-lubricated as the block and connecting rod deform under load.\u003c\/p\u003e\u003cp\u003eIn standard size, ACL specifies them for a connecting rod journal of 58.995 to 59.005 mm, with a bearing width of 23.55 mm. For that diameter, they recommend an oil clearance of approximately 0.060 to 0.072 mm, measured with a micrometer and bore gauge. If the crankshaft is ground, the measurement changes.\u003c\/p\u003e\u003cp\u003eThey do not have the silver-tin final plating found on standard bearings, so their dark, brownish-black and bluish color is factory-standard and does not indicate any defect. ACL advises against polishing the bearing surface to adjust clearance; if more is needed, combine them with the HX version, which provides an additional 0.025 mm of clearance.\u003c\/p\u003e\u003cp\u003eBefore ordering, confirm your crankshaft measurement (standard or ground); if you have any questions, write to us with your engine code.\u003c\/p\u003e","brand":"ACL","offers":[{"title":"Default Title","offer_id":50813134602574,"sku":"6B8396H-STD","price":95.38,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0816\/7329\/0062\/files\/c160b9299e5c37e0784be30096314929.jpg?v=1735904033","url":"https:\/\/driftandgrip.com\/en\/products\/acl-trimetal-reinforced-rod-bearings-landcruiser-diesel-4-2l-1hz","provider":"Drift \u0026 Grip","version":"1.0","type":"link"}
