ACL Race Series performance engine bearings are recognized as a premier brand throughout the motorsports world, with rod and main bearings used in race engines that have set records and won championships from Mexico to Bonneville. This connecting rod bearing set is precision-engineered for Mazda performance applications requiring 1.00mm oversize bearings.

Key Features:

• Hardened steel backs on all rod bearings improve the support of the bearing lining and assist with bearing retention in the housing
• Trimetal construction combining design, metallurgy and engineering for high performance applications
• No flash plating on the back of the bearings improves heat transfer and maximizes grip between bearings and housing
• Increased eccentricity compensates for bore distortion at high RPM and assists in the formation of hydrodynamic oil films
• High strength overlay plate with reduced thickness for improved fatigue properties
• Increased crush for improved bearing retention

One often overlooked part when building an engine is the bearings, and getting a quality set can directly determine the longevity of your engine. ACL Race Series bearings are designed to withstand higher RPM conditions and deliver the endurance and capability demanded by performance engines.
