6.7 Cummins Loaded O-Ring Cylinder Head | DK Engines DK-CU6.7-24VCHLO (2007.5–2018)
Revitalize your 2007.5–2018 6.7L Cummins with the DK Engines DK-CU6.7-24VCHLO Loaded O-Ring Cylinder Head — a brand-new, fully assembled solution engineered to fix common top-end issues and deliver long-term reliability.
This precision O-ringed head is the smart choice when you're dealing with blown head gaskets, loss of compression, overheating, or a warped factory head. The O-ring design adds a critical secondary sealing surface that helps maintain compression even under higher boost or cylinder pressures, making it a popular upgrade over stock heads.
Key Features & Benefits
- O-Ringed Combustion Deck — Precision-machined groove with stainless steel O-ring wire provides enhanced sealing pressure against the head gasket. Significantly reduces the risk of repeat head gasket failures.
- Fully Loaded (CHLO) — Comes completely assembled with all-new valvetrain components: black nitride coated valves, valve springs, seats, seals, retainers, and keepers. No core charge and no time wasted bench-building a used head.
- Brand New Casting — Not remanufactured or used. Delivers fresh structural integrity and consistent quality.
- Black Nitride Coated Valves — Superior heat, wear, and corrosion resistance for extended service life in demanding diesel applications.
- Direct-Fit Replacement — Engineered as a bolt-in solution for 2007.5–2018 Ram 2500, 3500, and 4500 trucks with the 6.7L 24-valve Common Rail Cummins.
Why Choose the DK-CU6.7-24VCHLO?
Factory 6.7L heads are prone to warping and gasket failure, especially on higher-mileage trucks or those with tuning. This loaded O-ring head gives you a fresh start with upgraded sealing performance and brand-new internals — saving labor time and reducing the chance of comebacks.
Note: Requires an MLS (Multi-Layer Steel) head gasket. Truck freight shipping only.
