ACL 4B1925A-.25 Oversized Rod Bearing Set

The ACL 4B1925A-.25 is engineered for high-performance applications, specifically designed for the Acura B18C VTEC engines from 1994 onwards. This rod bearing set utilizes advanced metallurgy and precision engineering to meet the demands of high RPM conditions, ensuring reliability and durability under extreme stress.

Key Features

  • High Strength Overlay Plate: Features a reduced thickness to enhance fatigue resistance, crucial for high-revving applications.
  • Hardened Steel Backs: All rod bearings come with hardened steel backs that improve support for the bearing lining and enhance retention within the housing.
  • Increased Crush: Designed with increased crush for better bearing retention during operation.
  • No Flash Plating: The elimination of flash plating on the back of the bearings optimizes heat transfer and maximizes grip between the bearings and their housing.
  • Enhanced Eccentricity: Increased eccentricity compensates for bore distortion at high RPM, aiding in the formation of hydrodynamic oil films.
  • 3/4 Grooved Main Bearings: Optimizes load-carrying surface area and improves oil flow to the connecting rod bearings.
  • Tight Wall Tolerances: Maintains consistent clearances for reliable performance.
  • Enlarged ID Chamfers: Designed where necessary to accommodate large fillet radii on performance crankshafts.
