Product Details

ACL Race Series connecting rod bearings are engineered for high-performance and racing applications where durability and reliability under extreme conditions are critical. These bearings feature advanced metallurgy and precise tolerances to handle the demanding loads and temperatures found in competition engines.

Key Features:

  • Race-proven design for high-performance and competition engines
  • -.025mm undersize for crankshaft journal machining and rebuilds
  • High-strength tri-metal construction for superior load capacity
  • Precision bore and wall thickness tolerances
  • Enhanced oil retention grooves for improved lubrication
  • Engineered to withstand extreme RPM and cylinder pressures

The -.025mm undersize allows these bearings to be used when crankshaft journals have been machined undersize during rebuilding or performance preparation. ACL Race Series bearings are a trusted choice among engine builders and professional racers worldwide.
