ACL Bearings Race Series High Performance Connecting Rod

ACL Race Series high performance connecting rod bearings, also called rod bearings or con rod bearings, are tri-metal engine bearings built for racing and high-performance engines. They are designed to hold up at higher RPM, where standard bearings can fail early. The line covers many popular 4, 6 and 8 cylinder engine applications.

Key Features:

• Tri-metal construction for load capacity and seizure resistance in demanding use
• High strength overlay plate with reduced thickness for improved fatigue properties
• Hardened steel backs support the bearing lining and help keep the bearing seated in the housing
• Increased crush for improved bearing retention
• Increased eccentricity to compensate for bore distortion at high RPM and help form hydrodynamic oil films
• Tight, consistent wall tolerances to help maintain consistent oil clearances
• Enlarged ID chamfers on bearing edges where needed to clear the large fillet radii on performance crankshafts

Race Series bearings are used in race engines across many motorsport disciplines, from sport compact drifting to NASCAR, NHRA and IHRA competition. They suit engine builders who want a durable, precisely manufactured rod bearing for a performance or track build.
