The ACL 4B1906H-STD rod bearing set is engineered for high-performance applications, specifically designed for the Acura/Honda K20A3 and F23A engines. This set features advanced metallurgy and precision engineering, ensuring durability and reliability under demanding conditions.

Key Features

  • High Strength Overlay Plate: The reduced thickness enhances fatigue resistance, making it suitable for high RPM scenarios.
  • Hardened Steel Backs: Each rod bearing is equipped with hardened steel backs, providing better support for the bearing lining and securing it within the housing.
  • Increased Crush: Improved bearing retention due to enhanced crush characteristics.
  • Optimized Heat Transfer: The elimination of flash plating on the back of the bearings improves heat dissipation and maximizes grip between the bearings and housing.
  • Increased Eccentricity: This design compensates for bore distortion at high RPM, aiding in the formation of hydrodynamic oil films.
  • 3/4 Grooved Main Bearings: Optimizes the load-carrying surface area and oil flow to the connecting rod bearings.
  • Tight Wall Tolerances: Consistent wall tolerances help maintain precise clearances for optimal performance.
  • Enlarged ID Chamfers: Designed to accommodate large fillet radii on performance crankshafts where necessary.
