ACL 5M1219-.50 Oversized Main Bearing Set

The ACL 5M1219-.50 is engineered for high-performance applications, specifically tailored for the 1997+ Mitsubishi 4G63/4G64 engines. This oversized main bearing set is designed to meet the demands of enthusiasts seeking reliability and durability under higher 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: All rod bearings come equipped with hardened steel backs, which provide superior support for the bearing lining and improve retention within the housing.
  • Increased Crush: Enhanced crush characteristics ensure improved bearing retention, critical for maintaining performance under stress.
  • Optimized Heat Transfer: The elimination of flash plating on the back of the bearings allows for better heat dissipation, maximizing grip between the bearings and their housing.
  • Enhanced Eccentricity: Increased eccentricity compensates for bore distortion at high RPM, facilitating the formation of hydrodynamic oil films essential for lubrication.
  • 3/4 Grooved Design: This design optimizes the load-carrying surface area and improves oil flow to the connecting rod bearings.
  • Tight Wall Tolerances: Consistent wall tolerances maintain precise clearances, crucial for engine performance.
  • Enlarged ID Chamfers: Chamfers on bearing edges accommodate larger fillet radii found on performance crankshafts.
