Designed specifically for high-performance applications, this set is crafted to meet the needs of serious automotive enthusiasts, particularly those working with Honda and Acura vehicles.

Key Features:

• High strength overlay plate with a reduced thickness, enhancing fatigue properties for better durability.
• Hardened steel backs on all rod bearings, providing improved support for the bearing lining and ensuring secure retention within the housing.
• Increased crush for enhanced bearing retention, ensuring that the bearings stay in place during high-stress conditions.
• Elimination of flash plating on the back of the bearings, which improves heat transfer and maximizes grip between the bearing and its housing.
• Increased eccentricity to counteract bore distortion at high RPM, aiding in the formation of hydrodynamic oil films.
• 3/4 grooved main bearings that optimize load-carrying surface area and oil flow to the conrod bearings.
• Tight and consistent wall tolerances to help maintain proper clearances for better performance.
• Enlarged ID chamfers on bearing edges to accommodate large fillet radii on performance crankshafts.
