ACL 8B663HXD-STD Race Connecting Rod Bearing Set

The ACL 8B663HXD-STD connecting rod bearing set is engineered for high-performance applications, particularly within the Chevrolet B Series and Kodiak models. This set is designed to meet the rigorous demands of racing and high RPM conditions, providing a durable and reliable solution for engine builders and performance enthusiasts alike.

Key Features

  • High-strength overlay plate with reduced thickness enhances fatigue resistance, ideal for high RPM applications.
  • Hardened steel backs on all rod bearings improve support for the bearing lining and enhance retention within the housing.
  • Increased crush for better bearing retention, ensuring stability under extreme conditions.
  • Elimination of flash plating on the back of the bearings optimizes heat transfer and maximizes grip between the bearings and housing.
  • Increased eccentricity compensates for bore distortion at high RPM, facilitating the formation of hydrodynamic oil films.
  • 3/4 grooved main bearings optimize load-carrying surface area and oil flow to the connecting rod bearings.
  • Tight and consistent wall tolerances maintain proper clearances for enhanced performance.
  • Enlarged ID chamfers on bearing edges accommodate large fillet radii on performance crankshafts.
