PISTON WITH RINGS

Use the Clevite H-Series Main Bearing Set when building your 2001-2013 GM 6.6L Duramax. Clevite H-Series 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 and high crush. 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. If you aren't sure which type of performance bearing to start with, the H series bearing will be your best choice. Requires thrust washer set TW-610S.
