CARRILLO DMHD6418H 6.6L DURAMAX PRO-H CONNECTING ROD SET (WITH H-11 BOLTS)

The CARRILLO DMHD6418H 6.6L Duramax Pro-H Connecting Rod Set with H-11 Bolts is engineered for those who demand both performance and durability in their 2001-2010 GM 6.6L Duramax engine builds. With an illustrious history dating back to 1963, Carrillo stands as a leader in custom connecting rod manufacturing, having supplied high-performance parts to a myriad of automotive and motorcycle platforms.

Crafted from a proprietary alloy that includes chrome, nickel, molybdenum, and vanadium, this connecting rod set meets stringent VAR (vacuum arc re-melt ASTM) standards. Each rod undergoes meticulous heat treatment processes validated by both suppliers and independent metallurgists to ensure the steel achieves exceptional physical and chemical properties. The resulting ultimate tensile strength reaches an impressive 195,000 psi, with a yield strength of 182,000 psi, ensuring reliability under extreme conditions while preserving low notch-sensitivity and ductility.

Manufactured from oversized forgings, these connecting rods guarantee optimal grain flow and eliminate potential surface inclusions. Utilizing state-of-the-art CNC machinery equipped with probing technology, Carrillo ensures precise dimensional integrity during production. Each component is subjected to rigorous magnaflux inspections and Rockwell tests to confirm proper heat treatment, culminating in a critical shot peening process that enhances fatigue resistance.

Designed specifically for high-demand applications, the Pro-H design not only provides exceptional strength but also enhances the overall performance of your Duramax engine. As a complete set of eight rods, this package includes premium H-11 tool steel bolts, ensuring your build is equipped with the best. Upgrade your engine's performance and reliability with the CARRILLO DMHD6418H Connecting Rod Set, where precision engineering meets high-performance expectations.

The Carrillo 6.6L Duramax Pro-H Connecting Rod Set With H-11 Bolts 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 H-11 bolts and is for use in a wide range of applications.
