The ACL 5M829A-STD main bearing set is engineered for high-performance applications, specifically designed to meet the demands of Chevrolet V8 engines from 1965 to 2000. These Trimetal engine bearings combine advanced metallurgy and precise engineering to provide exceptional durability and reliability under high RPM conditions.

Key Features

  • High Strength Overlay: The overlay plate features a reduced thickness, enhancing fatigue resistance for long-lasting performance.
  • Hardened Steel Backs: All rod bearings come with hardened steel backs, improving support for the bearing lining and ensuring secure retention within the housing.
  • Increased Crush: Optimized crush dimensions enhance bearing retention, ensuring stability during operation.
  • Improved Heat Transfer: The elimination of flash plating on the back of the bearings facilitates better heat dissipation, 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 for optimal lubrication.
  • 3/4 Grooved Design: The main bearings feature a 3/4 grooved configuration, optimizing load-carrying surface area and enhancing oil flow to the connecting rod bearings.
  • Tight Wall Tolerances: Consistent wall tolerances help maintain precise clearances, which is critical for performance applications.
  • Enlarged ID Chamfers: Designed to accommodate large fillet radii on performance crankshafts, ensuring compatibility with high-performance setups.
