Clevite MS-590H Series 302 SBF Clevite 77 H-Series Main Bearings

Clevite 77 H-Series Tri-Metal Main Bearing Set for the 302 Small Block Ford. 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 Main 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.
