The Clevite CB-634H Series is a set of H-Series Tri-Metal connecting rod bearings designed for the 302 Small Block Ford engine. These bearings are narrowed for clearance with aftermarket high-performance crankshafts featuring larger fillet radii. Suitable for racing applications, they offer medium eccentricity, high crush, hardened steel backs, and a thin bearing overlay. The H-Series bearings feature a Babbit outer layer, a copper-lead alloy second layer, and a steel back capable of withstanding loads up to 12,000 PSI, making them a common recommendation for high-performance and general racing use.
