Get Maximum Durability at High RPM with ACL Performance Race Series Rod and Main Bearing Sets

There is no better proving ground for parts than high performance and racing. In the heat of competition, the best products always finish first. With several decades of race wins in every form of professional racing the world over, ACL Performance Race Series Engine Bearings deliver proven high RPM endurance where other bearings grind to a halt. 

ACL Performance Race Series Rod Bearing and Main Bearing Sets are designed to thrive and survive in high-RPM environments. Features include:

• Tri-metal copper-lead alloy design provides high strength and excellent seizure resistance
• Hardened steel shells improve lining support and crush for better bearing retention
• Flash plating removal on the bearing backsides improves heat transfer
• Increased eccentricity compensates for bore distortion and improves hydrodynamic oil film formation
• Precise tolerances ensure consistent clearances for better oiling, durability, and fit
• Reduced thickness overlay plating improves fatigue
• 3/4-inch grooved main bearings optimize load carrying surface area and aid in proper oil flow to the rod bearings
• Enlarged ID chamfers on main bearing edges (where required) accommodate large fillet radius on high performance and racing crankshafts
• Available with or without friction-reducing coatings in standard and extra clearance sizes

ACL Performance Race Series Rod Bearing Sets and Race Series Main Bearing Sets are available for hundreds of 1947-2025 domestic and import engines.
