Clevite SBC Coated Main Bearings +.001″ MS909HXC
Clevite 77 Tri-Metal Connecting Main Bearing Set for Small Block Chevy. 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.
The H-Series bearings feature Clevite’s exclusive TriArmor coating, the industry’s only moly/graphite treatment. The sophisticated blend, in a low-friction PTFE polymer base, offers extraordinary protection and lubricity. They also have enlarged chamfers at the sides for greater crank-fillet clearance and are made without flash plating for better seating.
