Clevite 6G72 Engine Main Bearing Set.
These 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.
Use H -Series bearings with crankshafts that have oversize fillets and where engines run in the medium to high RPM range.
H-Series bearings should be used if contact patterns obtained with P-Series parts are too narrow. Contact patterns should ideally cover 2/3 to 3/4 of the bearing surface.
