Clevite CB1664H H-Series Connecting Rod Bearing - Set

The Clevite CB1664H is a high-performance H-Series connecting rod bearing set engineered for demanding racing and competition applications. Originally developed for NASCAR-style racing, these bearings deliver the strength and durability needed for medium to high RPM engines across all forms of motorsports competition.

H-Series Performance Features:

• Medium eccentricity design optimizes bearing contact patterns for enhanced load distribution
• Hardened steel backing provides superior strength and resistance to fretting
• High crush construction ensures maximum bearing retention under extreme conditions
• Thin overlay reduces risk of overlay fatigue and "hen tracking"
• Enlarged chamfers accommodate crankshafts with oversize fillets
• Non-flash plated for improved seating and contact
• TriMetal construction with lead-tin-copper overlay for excellent wear resistance

Ideal Applications:

• Medium to high RPM competition engines
• Crankshafts with oversized fillet radii
• Applications requiring optimal contact patterns covering 2/3 to 3/4 of bearing surface
• General purpose high-performance builds where P-Series contact patterns are too narrow

Clevite H-Series bearings are manufactured to exceed OEM specifications and provide the protection your engine needs against the destructive effects of friction and heat. The proven TriMetal bearing construction combines a steel backing, intermediate layer, and overlay to deliver exceptional strength, conformability, and durability under racing conditions.
