The ACL 8B745P-40 Trimetal Rod Bearing Set is engineered for high-performance applications, specifically designed for Chevrolet V8 engines from 1955 to 1967, including the 265, 283, 302, and 327 cubic inch variants. This set offers a robust solution for those looking to enhance their engine's reliability under demanding conditions.

Key Features

  • Constructed with a high-strength overlay plate that features reduced thickness, enhancing fatigue resistance during high RPM operation.
  • Hardened steel backs on all rod bearings provide superior support for the bearing lining, ensuring optimal retention within the housing.
  • Increased crush design improves bearing retention, minimizing the risk of displacement under load.
  • Flash plating has been eliminated from the back of the bearings, improving heat transfer and maximizing grip between the bearing and its housing.
  • Increased eccentricity compensates for bore distortion at high RPM, facilitating the formation of hydrodynamic oil films for better lubrication.
  • 3/4 grooved main bearings optimize load-carrying surface area and oil flow to the connecting rod bearings.
  • Tight and consistent wall tolerances help maintain precise clearances, crucial for performance applications.
  • Enlarged ID chamfers on bearing edges accommodate large fillet radii on performance crankshafts.
