ACL 5M1144H-STD High Performance Main Bearing Set

The ACL 5M1144H-STD is engineered for those who demand reliability and performance from their engine components. This main bearing set is specifically crafted for the Mitsubishi 4G63/4G64 6 Bolt 1st Gen DSM applications, providing the durability and precision needed for high RPM conditions.

Key Features

  • Tri-metal Construction: The bearings feature a high-strength overlay plate with reduced thickness, enhancing fatigue resistance and overall performance.
  • Hardened Steel Backs: Each rod bearing is equipped with hardened steel backs to improve support for the bearing lining and assist with retention within the housing.
  • Improved Crush Design: Increased crush enhances bearing retention, ensuring stability during operation.
  • Optimized Heat Transfer: The elimination of flash plating on the back of the bearings promotes better heat dissipation and maximizes grip between the bearings and their housing.
  • Enhanced Eccentricity: Designed to compensate for bore distortion at high RPM, facilitating the formation of hydrodynamic oil films.
  • 3/4 Grooved Main Bearings: This design 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 improved performance.
  • Enlarged ID Chamfers: Bearing edges are designed with enlarged ID chamfers to accommodate large fillet radii on performance crankshafts.
