Clevite CB-1663H-1 H-Series Performance Rod Bearing Set

The Clevite CB-1663H-1 is a high-performance connecting rod bearing set designed for competition engines and demanding applications. These H-Series bearings feature a medium level of eccentricity, high crush for maximum retention, and a hardened steel back for added strength and resistance to fretting. The thin overlay construction helps prevent overlay fatigue under extreme conditions.

H-Series Performance Features:

• Medium eccentricity design ideal for medium to high RPM applications
• Enlarged chamfers provide greater crankshaft fillet clearance
• Hardened steel back for superior strength and durability
• High crush design ensures maximum bearing retention
• Thin overlay construction prevents hen tracking and fatigue
• No flash plating for improved seating characteristics
• TriMetal construction meets or exceeds OEM standards

Application Notes:

H-Series bearings are engineered for crankshafts with oversize fillets and engines operating in medium to high RPM ranges. These bearings provide ideal contact patterns covering approximately 2/3 to 3/4 of the bearing surface. Originally developed for NASCAR-type racing, H-Series bearings are suitable for all types of competition engines where reliability and performance are critical.

Important: Clevite rod bearings are sold as paired sets (two bearing halves for one connecting rod). For a complete 6-cylinder engine, order quantity of 6 sets.
