ACL 8B743HX-STD Race Series Conrod Rod Bearing Set

The ACL 8B743HX-STD Race Series Conrod Rod Bearing Set is engineered for high-performance applications, specifically designed to meet the demands of racing and high RPM conditions. This set combines advanced metallurgy and precision engineering to ensure optimal performance and durability in your Chevrolet V8 engine.

Key Features

  • Utilizes a high-strength overlay plate with reduced thickness to enhance fatigue resistance, making it suitable for high-stress environments.
  • Hardened steel backs on all rod bearings provide superior support for the bearing lining, enhancing retention within the housing.
  • Increased crush design enhances bearing retention, crucial for maintaining stability during aggressive driving.
  • Flash plating elimination on the back of the bearings improves heat transfer and maximizes grip between the bearings and their housing.
  • Increased eccentricity compensates for bore distortion at high RPM, facilitating the formation of hydrodynamic oil films for improved lubrication.
  • 3/4 grooved main bearings optimize load-carrying surface area and ensure efficient oil flow to the conrod bearings.
  • Tight and consistent wall tolerances maintain precise clearances, critical for performance applications.
  • Enlarged ID chamfers on bearing edges accommodate large fillet radii found on performance crankshafts.
