The Clevite CB1664HC is a high-performance connecting rod bearing set designed for Oldsmobile V8 and Aurora Indy engines. This H-Series bearing features Clevite's exclusive TriArmor coating, a sophisticated moly/graphite treatment in a low-friction PTFE polymer base that delivers exceptional protection and lubricity for demanding racing applications.

Key Features:

• TriArmor moly/graphite coating provides superior wear resistance and reduced friction
• Hardened steel backing with thin overlay for maximum durability
• Medium level of eccentricity with high crush factor for optimal oil retention
• Manufactured without flash plating for improved seating and contact
• Enlarged chamfers at bearing sides for greater crankshaft fillet clearance
• Copper-lead alloy layer with electroplated babbitt surface reduces drag and increases horsepower

Originally developed for NASCAR racing, these H-Series bearings are ideal for all types of high-performance and competition engines running at medium-to-high RPM ranges. The advanced bearing design ensures reliable performance under extreme loads and temperatures.
