5.9 Cummins New Cylinder Head Loaded with Valve Train – DK Engine Parts (DK-CU5.9CR-CHL)

Restore factory performance and reliability to your 2003–2007 5.9L 24V Common Rail Cummins.

The DK Engine Parts DK-CU5.9CR-CHL is a brand-new, fully loaded cylinder head designed specifically for 2003–2007 Dodge Ram 2500 and 3500 trucks with the 5.9L 24-valve Common Rail Cummins engine. Unlike remanufactured heads that can carry hidden stress fractures or thinned decks from previous machining, this is a fresh casting that delivers consistent quality and long-term durability.

This assembly arrives ready to install with a complete new valve train, including black nitride-coated valves, springs, seats, seals, retainers, and keepers. The black nitride coating provides superior resistance to the extreme heat and pressure of diesel combustion while reducing friction for smoother operation.
