ACL 4B1146H-.025 High Performance Rod Bearing Set

The ACL 4B1146H-.025 rod bearing set is engineered for high-performance applications, specifically designed for the Mitsubishi 4G63 and 4G64 engines. These bearings are crafted using a tri-metal construction that combines durability with optimal performance, making them suitable for high-RPM conditions typical in motorsport and performance builds.

Key Features

  • High-strength overlay plate with reduced thickness enhances fatigue resistance.
  • Hardened steel backs provide superior support for the bearing lining, ensuring reliable retention within the housing.
  • Increased crush enhances bearing retention for improved stability under load.
  • Elimination of flash plating on the back improves heat transfer and maximizes grip between the bearings and housing.
  • Increased eccentricity compensates for bore distortion at high RPM, aiding in the formation of hydrodynamic oil films.
  • 3/4 grooved main bearings optimize load-carrying surface area and oil flow to conrod bearings.
  • Tight and consistent wall tolerances maintain precise clearances for optimal performance.
  • Enlarged ID chamfers accommodate large fillet radii on performance crankshafts.
