Clevite CB-634H Series 302 SBF Clevite 77 H-Series Rod Bearings

Clevite 77 H-Series Tri-Metal Connecting Rod Bearing Set for the 302 Small Block Ford with optional TriArmor Coating. Narrowed for clearance with aftermarket high performance crankshafts with larger fillet radius. Suitable for all forms of racing engines, H-Series bearings offer a medium level of eccentricity, a high crush factor with hardened steel backs and thin bearing overlay.

H-Series rod bearings have a Babbit outer layer, a copper-lead alloy second layer and a precision steel back capable of carrying loads up to 12,000 PSI. H-Series Clevite Bearings are likely the most frequently use for high performance / general racing applications. This is typically the bearing type we will recommend in almost all situations.

The TriArmor Coating adds an additional extremely thin layer of Moly & Graphite to the top surface of the bearing reducing friction and drag. It can also offer increased protection during startup – it’s a great option for competition engines.
