Overview

Clevite Coated H-Series Main Bearings

Clevite coated H-Series main bearings were developed primarily for NASCAR racing, but are also well-suited to other types of competition engines. They are especially good for engines that run at medium-to-high revs. They have steel backings with carefully selected overlays and a high crush factor, plus a medium level of eccentricity. These 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. Clevite H-Series bearings have enlarged chamfers at the sides for greater crank-fillet clearance and are made without flash plating for better seating. They come with 180 degree oil grooves, and can be ordered with an extra 0.001 in. of clearance if needed.
