Cylinder Heads

2007.5–2009 Dodge Ram 2500 & 3500 6.7L Cummins Heavy-Duty Replacement Cylinder Head

Prevent catastrophic dropped valve seats, stop coolant leaks from cracked factory castings, and restore absolute compression integrity with the heavy-duty 2007.5–2009 6.7L Cummins replacement cylinder head from Full Force Diesel. Heavy-duty Ram trucks working under extreme commercial towing workloads, high boost pressures, or aggressive custom engine tuning subject their top-end castings to immense thermal cycling and peak cylinder pressures. Over years of severe service, factory valve seats can loosen from heat fatigue and factory decks can crack between the ports, leading to loss of compression, coolant contamination, and engine failure. Upgrading to a heavy-duty replacement cylinder head provides a rock-solid foundation designed to withstand high-boost, high-heat environments.

Advanced Thermal Integrity: Reinforced Castings and Optimized Coolant Passages

Transitioning away from a damaged or warped factory head to a heavy-duty replacement casting completely safeguards your engine's top end:

• Thicker Deck Faces and Improved Walls: Premium replacement cylinder heads feature reinforced casting designs with thicker deck faces and strengthened internal webbing, engineered to resist warping and cracking under sustained high-EGT towing conditions.

• Optimized Cooling Flow: Redesigned internal coolant passages enhance thermal transfer around the combustion chambers, keeping operating temperatures stable when your inline-six is pulling heavy loads up steep grades.

Precision Machining and Professional-Grade Foundation

Engineered to accept your matching valvetrain components and deliver a flawless seal right out of the box:

• Precision-Machined Valve Seats and Guides: Factory-hardened valve seats and guides are precision-machined to ensure absolute concentricity and an airtight seal, eliminating the risk of seat dropping.

• Flat Ground Mounting Surfaces: Precision surface-ground cylinder head decks ensure an even, uniform clamp against your engine block when paired with heavy-duty head studs and quality gaskets.

At Full Force Diesel, we carry the rugged, street-tested mechanical hardware and machine-shop-certified components your transitional 3rd Generation inline-six needs to handle maximum boost and heat. Secure your truck's engine foundation by adding this heavy-duty 2007.5–2009 6.7L Cummins cylinder head to your build today.
