Clevite Con Rod Bearing Set

The Clevite CB634HNC is a set of H-Series TriArmor coated rod bearings designed for Small Block Ford engines. These bearings are suitable for competition engines, particularly those operating at medium to high RPMs.

They feature hardened-steel backings with thin overlays, a high crush factor, and medium eccentricity. The TriArmor coating is a unique moly/graphite treatment in a PTFE polymer base for enhanced protection and lubricity, increasing bearing life in race and performance street engines. The bearings also include enlarged chamfers for greater crank-fillet clearance and are manufactured without flash plating for improved seating. They are designed for crankshafts with oversize fillets and are available in standard size for Ford 260, 289, and 302 engines with a 2.123-inch rod journal.
