Product Details

ACL Race Series connecting rod bearings are engineered for high-performance and racing applications where durability and precision are critical. These bearings feature advanced metallurgy and coating technologies designed to withstand extreme loads, high RPM operation, and elevated temperatures commonly encountered in competition engines.

Key Features:

  • Race Series construction for maximum durability under extreme conditions
  • -.025mm undersize for precision crankshaft machining and rebuilds
  • Advanced bearing materials optimized for high load capacity
  • Proprietary surface treatments for reduced friction and improved oil retention
  • Manufactured to strict tolerances for consistent performance
  • Suitable for naturally aspirated and forced induction applications

ACL bearings are trusted by engine builders and racers worldwide for their consistent quality and performance. The -.025mm undersize allows for proper bearing crush and oil clearance when working with refinished crankshafts, making these ideal for performance rebuilds and race engine preparation.

Warp speed shipping, best price on the internet, and awesome back-up camera for our travel trailer. Very happy!
