Product Details

ACL Race Series connecting rod bearings are engineered for high-performance and racing applications where reliability under extreme conditions is critical. These bearings feature advanced materials and coatings designed to withstand the increased loads, temperatures, and RPMs associated with modified and race engines.

Key Features:

  • Race-proven design for high-performance and competition use
  • Premium bearing materials for superior wear resistance
  • Optimized oil clearances for maximum protection under load
  • Enhanced fatigue strength for extended durability at high RPM
  • Precision manufacturing to OEM tolerances and beyond
  • Undersize bearing (.50mm undersize) for use with reground crankshafts

ACL Race Series bearings are a popular choice among engine builders and racers who demand the ultimate in bearing technology. The .50mm undersize specification makes these bearings ideal for crankshafts that have been machined to repair wear or damage, ensuring proper oil clearance and optimal performance.
