ACL 1B2500H-STD-2 Connecting Rod Bearings

The ACL 1B2500H-STD-2 connecting rod bearings are engineered for high-performance applications, specifically designed to meet the rigorous demands of motorsport and high-RPM conditions. These tri-metal bearings combine advanced metallurgy and precision engineering to provide superior performance and durability, making them an essential upgrade for serious automotive enthusiasts.

Key Features

  • High-strength overlay plate with reduced thickness enhances fatigue resistance, allowing for reliable operation at elevated RPMs.
  • Hardened steel backs improve support for the bearing lining and enhance retention within the housing, ensuring stability during operation.
  • Increased crush provides better bearing retention, preventing movement under extreme loads.
  • Elimination of flash plating on the bearing backs improves heat transfer, maximizing grip between the bearing and its housing.
  • Enhanced eccentricity compensates for bore distortion at high RPMs, aiding in the formation of hydrodynamic oil films for optimal lubrication.
  • 3/4 grooved main bearings optimize load-carrying surface area and oil flow to the connecting rod bearings.
  • Tight and consistent wall tolerances maintain reliable clearances, crucial for performance applications.
  • Enlarged ID chamfers accommodate large fillet radii on performance crankshafts, facilitating smoother operation.
