CP Carrillo Duramax Pro-H Connecting Rods | DM6418S | 2001-2010 GM Duramax 6.6L

CP-Carrillo connecting rods are a must have in your 2001-2010 GM Duramax 6.6L engine. They are made of a proprietary chrome, nickel, moly, vanadium alloy which meets all VAR (vacuum arc re-melt ASTM standards). The head is validated by an independent metallurgist who confirms the desired physical and chemical properties of the steel. All heat treat processes are done via a mar-aged operation, resulting in UTS of 195,000 with a yield of 182,000 while maintaining the critical elements of low notch sensitivity and ductility.

All CP-Carrillo connecting rods are manufactured from an oversized forging resulting in the proper grainflow, as well as the surface removal of any potential inclusions or surface conversions generated by the forging process. All critical CNC machines are equipped with probing to accurately validate dimensional integrity. In the production process each part is magnafluxed at least twice as well as Rockwell tested to validate the heat treat procedure. A final shotpeen operation completes the part.

This connecting rod set comes with CARR Multiphase bolts, for more extreme applications.
