The ACL Race Series connecting rod bearings are engineered for high-performance and racing applications where extreme loads and temperatures demand superior durability. These bearings feature ACL's advanced metallurgy and specialized coatings designed to withstand the rigors of competition use.

Key Features:

  • Race Series construction for maximum strength and durability under extreme conditions
  • .25mm (0.010") undersize for precision fitting and crankshaft journal restoration
  • Advanced tri-metal construction with high-performance bearing material
  • Proprietary coating technology reduces friction and improves oil retention
  • Precision manufactured to strict tolerances for optimal clearances
  • Designed for high RPM operation and increased bearing loads

ACL Race Series bearings are the choice of professional engine builders and racers worldwide. The undersize dimension allows for proper bearing clearance when using a reground crankshaft or compensating for wear.
