They are the standard choice when opening the engine for performance builds.\u003c\/p\u003e\u003cp\u003eThese are tri-metal bearings: a SAE 1010 steel backing, a copper, lead, and tin layer of approximately 0.3 mm, a nickel barrier, and a surface layer of lead, tin, and copper that conforms to the crankshaft surface and resists seizing. In connecting rod bearings, the surface layer is thinner to better withstand fatigue.\u003c\/p\u003e\u003cp\u003eACL manufactures them with more \"crush\" than a standard bearing to ensure they are held securely and dissipate heat better, and with more eccentricity, which helps them maintain the oil film when the housing deforms at high RPMs.\u003c\/p\u003e\u003cp\u003eIn standard size, ACL specifies them for a connecting rod journal of 51.981 to 51.999 mm, with a bearing width of 19.5 mm. For this diameter, they recommend an oil clearance of approximately 0.055 to 0.065 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 final silver-tin 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\u003eNot sure if your crankshaft is standard size?
