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 specialized coatings designed to withstand extreme cylinder pressures, high RPM operation, and elevated temperatures found in competition engines.

Key Features:

  • Race-proven design for maximum reliability under extreme stress
  • -.25mm undersize for crankshaft journal machining and rebuild applications
  • High-strength tri-metal construction with performance bearing material
  • Proprietary surface treatments for enhanced wear resistance and oil retention
  • Precision manufacturing to tight tolerances for optimal clearances
  • Designed for forced induction, high compression, and high RPM applications

ACL Race Series bearings are trusted by professional engine builders and racers worldwide. The -.25mm undersize allows for proper clearance when crankshaft journals have been machined or require oversized bearings for optimal fit. Always verify bearing clearances during installation using plastigage or a micrometer.
