ACL Bearings Race Series Rod Standard Size

ACL Race Series connecting rod bearings, also called rod bearings or con rod bearings, are tri-metal performance engine bearings built for racing and high-RPM use. ACL has more than half a century of experience in race bearing design, engineering and metallurgy. The Race Series is made for engines that see higher loads and speeds than standard bearings are designed for.

Key Features:

• High-strength overlay plate with reduced thickness for better fatigue properties
• Hardened steel backs that 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 between the bearing and its housing
• Increased eccentricity to compensate for bore distortion at high RPM and to help form hydrodynamic oil films
• Tight, consistent wall tolerances to help you hold consistent clearances
• Enlarged ID chamfers on bearing edges where required, to clear the large fillet radii on performance crankshafts

Race Series rod bearings are available for many popular 4-, 6- and 8-cylinder engine applications. They suit performance builds, track cars and competition engines that need reliable bearing protection under heavy load.
