Honda B16A / B18C / B20C / K20A / K24 ACL Race Main Bearing Set (Calico CT-1 coating)

ACL Race Series CT-1 Coated Rod Bearings combine the proven ACL Race Series tri-metal construction with a low-friction CT-1 polymer coating, providing additional protection during start-up, high-load operation, and marginal lubrication conditions.

Race series bearing features:

• Designed to withstand higher RPM conditions.
• High strength overlay plate with reduced thickness for improved fatigue properties.
• Hardened steel backs on all rod bearings to improve the support of the bearing lining and assist with bearing retention in the housing.
• Increased crush for improved bearing retention.
• Elimination of flash plating on the back of the bearings to improve heat transfer through the bearing sand to maximize the grip between the bearings and its housing.
• Increased eccentricity to compensate for bore distortion at high rpm and to assist in the formation of hydrodynamic oil films.
• 3/4 grooved Main Bearings to optimize bearing load carrying surface area and oil flow to the conrod bearings.
• Tight consistent wall tolerances to help you maintain consistent clearances.
• Enlarged ID chamfers on bearing edges where required to accommodate large fillet radius on performance crankshafts.
