ACL Bearings 8B1227HC-10 Race Series Connecting Rod Bearing Set Undersize - 010

The ACL Bearings 8B1227HC-10 is a high-performance Race Series connecting rod bearing set designed for demanding motorsports applications. Engineered with precision to meet the rigorous requirements of racing engines, this bearing set delivers exceptional durability and reliability under extreme conditions.

Race Series Construction:

• Tri-metal construction with high-strength overlay plate featuring reduced thickness for improved fatigue properties
• Hardened steel backing on all rod bearings to improve support of the bearing lining and assist with bearing retention in the housing
• Increased crush for improved bearing retention and reduced risk of bearing spin
• Enhanced eccentricity to compensate for bore distortion at high RPM and assist in formation of hydrodynamic oil films
• Elimination of flash plating on bearing backs to improve heat transfer and maximize grip between bearings and housing

Specifications:

• .010" undersize for use with crankshafts that have been ground .010" undersize
• Standard oil clearance (HC designation)
• Manufactured to exacting tolerances with particular attention to wall thickness accuracy

ACL Race Series bearings are trusted by professional engine builders and racers worldwide, from sport compact drift racing to NASCAR, IHRA, and NHRA competitions. The unique combination of advanced design, superior metallurgy, and precision engineering provides these performance bearings with the endurance and capability to perform where standard bearings cannot.
