Mahle Clevite H-Series Rod Bearings

Clevite H-Series bearings were developed primarily for use in NASCAR type racing, but are suitable for all types of competition engines. H-Series bearings have a medium level of eccentricity, high crush, and rod bearings have a hardened steel back and thin overlay. These bearings also have enlarged chamfers for greater crankshaft fillet clearance and are made without flash plating for better seating.
