ACL Bearings Race Series Connecting Rod

ACL Bearings Race Series connecting rod bearings (rod bearing sets) are built for high-performance and racing engines. They use a trimetal design with modern metallurgy and are made to hold up under high RPM and heavy loads. They suit street, strip and track builds.

Key Features:

• High-strength overlay plate with reduced thickness for better fatigue resistance
• Hardened steel backs support the bearing lining and help keep the bearing seated in the housing
• Increased crush for better bearing retention
• No flash plating on the back of the bearing, which improves heat transfer and grip in the housing
• Increased eccentricity to compensate for bore distortion at high RPM and help form hydrodynamic oil films
• Tight, consistent wall tolerances to help maintain accurate clearances
• Enlarged ID chamfers on bearing edges where required, to clear the large fillet radii on performance crankshafts

Race Series bearings normally look dark and tarnished, in black, brown or blue tones. This comes from the copper-containing electroplated overlay. It is cosmetic only and does not affect bearing operation.

ACL Race Series bearings are used in many racing engines and are available for a wide range of domestic and import applications. Choose the correct variant for your engine and desired clearance.
