ACL 4B4390-STD Rod Bearing Set

The 4B4390-STD by ACL is engineered for high-performance applications, providing exceptional durability and reliability for your engine. This rod bearing set is specifically designed for the Ford 4 2.0L Duratec engine, ensuring a precise fit and optimal performance.

Key Features

  • Trimetal Construction: Features a high-strength overlay plate with reduced thickness, enhancing fatigue resistance under higher RPM conditions.
  • Hardened Steel Backs: Each rod bearing is equipped with hardened steel backs to improve support for the bearing lining and enhance retention within the housing.
  • Increased Crush: Designed with increased crush for improved bearing retention, ensuring stability during operation.
  • Optimized Heat Transfer: The elimination of flash plating on the back of the bearings enhances heat transfer efficiency, maximizing 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 oil flow to the connecting rod bearings for improved lubrication.
