CARRILLO DMHD6418S 6.6L DURAMAX PRO-H CONNECTING ROD SET (WITH CARR BOLTS)

The Carrillo DMHD6418S 6.6L Duramax Pro-H Connecting Rod Set is an essential upgrade for any serious builder of the 2001-2010 GM 6.6L Duramax engine. Renowned since 1963 for its engineering excellence, Carrillo has solidified its reputation as the premier custom connecting rod manufacturer, supplying high-performance components across automotive and motorcycle industries.

Engineered from a proprietary chrome, nickel, moly, and vanadium alloy, this rod set meets stringent VAR ASTM standards for durability and reliability. The meticulous heat treatment processes, validated by both suppliers and independent metallurgists, ensure an impressive ultimate tensile strength (UTS) of 195,000 psi and a yield strength of 182,000 psi, while preserving essential qualities such as low notch sensitivity and excellent ductility.

Each connecting rod in this set is crafted from oversized forgings, promoting optimal grain flow and eliminating potential surface inclusions. The advanced precision of Carrillo’s CNC machining is backed by rigorous probing and at least two rounds of magnaflux testing on each component, confirming dimensional integrity and resilience. To cap off their production, rods undergo Rockwell testing to ensure consistent heat treatment results, and a final shot-peening process enhances fatigue resistance.

Designed for high-torque and extreme performance applications, this set comes complete with CARR Multiphase bolts. Its Pro-H design and availability as a set of eight make it a crucial component for those looking to push their Duramax engine to the limits. Elevate your build and ensure reliability with the Carrillo DMHD6418S 6.6L Duramax Pro-H Connecting Rod Set.

The Carrillo 6.6L Duramax Pro-H Connecting Rod Set is a must have in your 2001-2010 GM 6.6L Duramax engine build. Since 1963, Carrillo is recognized as the preeminent custom connecting rod manufacturer in the world. Carrillo has provided custom and prototype connecting rods to virtually every major automotive and motorcycle venue, most notably to the high performance and speed equipment industry

Carrillo uses proprietary chrome, nickel, moly, vanadium alloy which meets all VAR (vacuum arc re-melt ASTM standards). The heat is validated, both by the supplier and an independent metallurgist whom confirm the desired physical and chemical properties of steel.  All heat treat processes are 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 Carrillo connecting rods are manufactured from an oversized forging resulting in the proper grain flow as well as the surface removal of any potential inclusions or surface conversions generated by the forging process. All critical CNC machines at Carrillo are equipped with probing to accurately validate dimensional integrity. In the production process each part is magnafluxed at least twice, further each piece is Rockwell tested to validate the heat treat procedure. A final shot peen operation completes the part. This connecting rod set comes with CARR Multiphase bolts and is generally for use in more extreme applications.
