Product Details

The ACL Bearings 4B1630H-.025 Race Series connecting rod bearings are engineered for high-performance and racing applications where durability and precision are critical. These bearings feature ACL's Race Series construction, designed to withstand the extreme loads and temperatures encountered in competitive motorsports and performance engine builds.

Key Features:

  • Race Series construction for maximum strength and reliability
  • -.025mm undersize for precision fitting and crankshaft journal repair
  • Advanced tri-metal bearing material for superior wear resistance
  • Optimized oil clearances for high-RPM performance
  • Enhanced fatigue strength to handle extreme cylinder pressures
  • Precision-machined to tight tolerances for consistent performance

ACL Race Series bearings are a popular choice among engine builders and racers who demand components that can handle boosted applications, high compression ratios, and extended periods of high-load operation. The undersize specification makes these bearings ideal for engines with machined crankshafts or those requiring precise bearing clearance adjustments.
