CLEVITE COATED H-SERIES STD CONROD BEARINGS CLCB743HNK STD SUIT CHEV BB 366-502 V8 H-Series Bearings Clevite coated H-Series rod bearings were developed primarily for NASCAR racing, but are also well suited to other types of competition engines. They're especially good for engines that run at medium-to-high revs. They have hardened-steel backings with thin overlays and a high crush factor, plus a medium level of eccentricity. 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. The Clevite coated rod bearings are available with various under-sizes, including 0.001 in. of clearance for polished journals
