ACL Bearings 8B1227HC-01 Race Series Connecting Rod Bearing Set Chevy Small Block

ACL Race Series performance engine bearings are recognized as a premier brand throughout the motorsports world, delivering championship-winning performance in high-RPM racing applications. This connecting rod bearing set is engineered specifically for Chevrolet small block V8 engines including 262, 267, 302, 305, 307, 327, and 350 cubic inch displacements.

Key Features:

• Race Series bearings are 0.0005" thinner per half to give 0.001" extra clearance for standard sized crankshafts, optimizing oil film thickness for high-performance applications
• Calico CT-1 dry film lubricant coating provides superior protection during startup and extreme loads
• Trimetal construction with lead, tin, copper and nickel for superior strength and seizure resistance
• Hardened steel backs improve bearing lining support and assist with bearing retention in the housing
• Increased eccentricity compensates for bore distortion at high RPM and assists in hydrodynamic oil film formation
• High-strength overlay plate with reduced thickness for improved fatigue properties

Race Series rod and main bearings are standard components in race engines that have set records and won championships from Mexico to Bonneville, from sport compact drift racing to small block NASCAR, IHRA and NHRA competitions. The unique combination of advanced metallurgy and precision engineering makes these bearings the choice of professional engine builders worldwide.
