Performance Clevite H series MAIN BEARING Sets

Main Bearings - Performance Clevite H series MAIN BEARING Sets
CHECK FOR FILLET CLEARANCE!
These bearings were developed primarily for NASCAR type racing, but are suitable for all types of competition engines. H series bearings have a medium level of eccentricity, high crush, & conrod bearings have a hardened steel back & thin overlay. The chamfers are enlarged for greater crankshaft fillet clearance, & are made without flash plating for better seating. Mains have grooved upper halves and plain lower halves. Ideal for engines running in the medium to high RPM range. Contact pattern should be 2/3 to 3/4 of the bearing surfaces.
