Clevite CB1665HNDC1 H-Series Connecting Rod Bearing

The Clevite CB1665HNDC1 is a high-performance H-Series connecting rod bearing designed for custom engine applications requiring Honda journal crankshaft specifications with small journal rod sizing. This tri-metal bearing features a hardened steel back with a copper-lead alloy intermediate layer and a thin overlay, engineered to withstand the demanding conditions of competition and high-performance engines.

Key Features:

• H-Series tri-metal construction with hardened steel backing for maximum strength
• Medium level of eccentricity with high crush factor for optimal seating
• Narrowed design (N) provides greater clearance for aftermarket crankshafts with larger fillet radius
• Dowel hole configuration (D) for positive positioning
• .001 inch extra oil clearance (C1) for high-performance applications
• Enlarged chamfers for superior crankshaft fillet clearance
• No flash plating for improved bearing seating and heat transfer
• Thin overlay reduces heat buildup in high-RPM applications

Originally developed for NASCAR racing applications, Clevite H-Series bearings are ideal for competition engines operating in medium to high RPM ranges. The CB1665HNDC1 is specifically designed for custom builds using Honda journal crankshafts paired with small journal connecting rods, making it perfect for hybrid engine combinations and performance builds requiring precise bearing specifications.
