Clevite High Performance 6G72 Main Bearing

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.
