Product Details

The ACL Bearings 4B1630H-.25 Race Series connecting rod bearings are engineered for high-performance racing applications where durability and reliability are critical. These bearings feature ACL's Race Series construction, designed to withstand extreme loads, high RPM operation, and elevated temperatures common in competition engines.

Key Features:

  • Race Series performance-grade construction for demanding applications
  • -.25mm undersize for use with reground crankshafts
  • Advanced tri-metal bearing technology for superior strength and wear resistance
  • Precision-engineered bearing geometry for optimal oil film retention
  • Enhanced fatigue resistance for extended service life under extreme conditions
  • Manufactured to strict tolerances for consistent performance

ACL Race Series bearings are the choice of professional engine builders and racers worldwide, offering the durability needed for high-output engines in motorsports applications. The -.25mm undersize dimension allows for proper bearing clearances when crankshafts have been machined undersize during rebuilding.
