ACL 5M8297-.75 0.75mm Oversized Main Bearing Set

The ACL 5M8297-.75 main bearing set is engineered specifically for high-performance applications within the Subaru EJ18, EJ20, EJ22, and EJ25 engines. This set is designed to meet the demands of higher RPM conditions, making it an essential upgrade for those looking to enhance engine durability and performance.

Key Features

  • Trimetal Construction: The bearings feature a high-strength overlay plate with a reduced thickness that improves fatigue resistance, ensuring longevity under stress.
  • Hardened Steel Backs: Each bearing is equipped with hardened steel backs, providing enhanced support for the bearing lining and improving retention within the housing.
  • Optimized Crush Design: Increased crush enhances bearing retention, ensuring stability during operation.
  • Heat Transfer Efficiency: The elimination of flash plating on the back of the bearings improves heat dissipation and maximizes grip between the bearing and housing.
  • High RPM Performance: Increased eccentricity compensates for bore distortion at elevated RPMs, aiding in the formation of hydrodynamic oil films for better lubrication.
  • 3/4 Grooved Configuration: This design optimizes the load-carrying surface area and promotes effective oil flow to the connecting rod bearings.
  • Consistent Wall Tolerances: Tight tolerances help maintain consistent clearances, which is critical for engine performance.
  • Enlarged ID Chamfers: Designed to accommodate large fillet radii on performance crankshafts, enhancing compatibility and reliability.
