Thumbnail Filmstrip of LLY Duramax New Cylinder Heads Loaded with Valve Train DK Engines DK-GMLLY-CHL Images
Investing in the performance and longevity of your LLY Duramax engine is simple with the DK Engines DK-GMLLY-CHL New Cylinder Heads Loaded with Valve Train. These aren't just replacement parts; they are a critical upgrade for your 2004.5-2005 6.6L V8 LLY engine. The cylinder head is an absolutely vital component, working with the cylinder block to form the combustion chamber—the very space where the fuel ignites and powers your vehicle. Specifically designed for the LLY Duramax, these aluminum cylinder heads are engineered for superior heat dissipation and weight reduction, which are key benefits over heavier, less efficient materials. By containing all necessary valves, injectors, and moving parts, this assembly ensures optimal airflow and fuel delivery, restoring your Duramax to peak operating performance.
- Complete Valve Train: This product is delivered as (2) brand new cylinder heads that are fully loaded with a complete, all-new valve train, saving you time and ensuring perfect component matching.
- Premium Internal Components: Includes all new valves, springs, seats, seals, retainers, and keepers.
- Enhanced Durability: Features black nitride coated valves for exceptional wear resistance and longevity under extreme diesel operating conditions.
- Engine Specificity: Precisely designed for the 6.6L V8 LLY Duramax engine applications from mid-2004 to the end of 2005, known for their 32-valve design.
- High-Quality Material: Constructed from aluminum to provide better heat dissipation and a lighter engine package.
- Peace of Mind: Backed by a Limited 1-Year Warranty.
By choosing the DK Engines DK-GMLLY-CHL complete cylinder head assembly, you are making a smart decision to ensure the heart of your LLY Duramax operates reliably and efficiently for years to come. You benefit from a brand-new component that eliminates the guesswork and potential failures associated with resurfaced or remanufactured heads, guaranteeing a fresh start for your engine's combustion system. With all critical valve train components pre-installed and featuring high-end enhancements like black nitride coated valves, this product is the straightforward, high-quality solution you need to maintain the power and dependability of your iconic Duramax diesel.
Fitment Notes:
- GM Duramax 6.6L – 2004.5-2005 – LLY VIN Code ‘2’
- The ‘LLY’ engine is the first year to use connector ‘keys’ on the injector (the circled portion).
