LBZ Duramax New Cylinder Head Loaded with Valve Train – DK Engine DK-GMLBZ-CHL
Restore power, reliability, and peace of mind to your 2006–2007 LBZ Duramax with these brand-new cylinder heads from DK Engine Parts. Sold as a pair, this complete assembly is precision-engineered as a direct replacement for damaged, cracked, or worn factory heads.
Unlike remanufactured or used heads, this is a brand-new casting that comes fully loaded with valve train — saving you hours of labor and ensuring every component is perfectly matched.
Includes:
- 1 New LBZ Duramax Cylinder Head
- Complete loaded valve train: new valves, valve springs, valve seats, valve stem seals, retainers, and keepers
- Black nitride-coated valves for superior wear resistance and extended service life
Key Features & Benefits
- Ready-to-install design — No need to source or assemble individual valve train components
- Black nitride valves — Significantly better wear resistance than standard valves under the extreme heat and pressure of diesel operation
- OEM-quality new casting — Meets or exceeds factory specifications with proper injector and glow plug mounting points
- Precision-machined for excellent sealing and performance
- Internal oil and coolant passages engineered for proper thermal management
Important Fitment Information This cylinder head fits LBZ Duramax engines only (2006–2007 GM 6.6L).
- VIN codes: ‘2’ or ‘D’
- Head casting number: 476-1
This head will NOT fit LLY engines. Please verify your engine code before ordering. If you’re unsure, contact us — we’re happy to help confirm fitment.
Vehicle Compatibility
- 2006–2007 Chevrolet Silverado 2500HD / 3500HD (LBZ)
- 2006–2007 GMC Sierra 2500HD / 3500HD (LBZ)
Recommended for: Head gasket failures, cracked heads, valve train wear, or full engine rebuilds. For maximum reliability (especially in modified or high-torque applications), we strongly recommend pairing this head with new head gaskets and ARP head studs.
Specifications
- Part Number: DK-GMLBZ-CHL
- Includes: 1 Cylinder Head (loaded with valve train)
- Warranty: Limited 1-Year Warranty
Why buy this head? Factory aluminum Duramax heads are known to crack or develop valve train issues over time. This new loaded head gives you a fresh start with upgraded valve durability and dramatically reduced installation time compared to rebuilding an old head.
Get your LBZ Duramax back on the road stronger and more reliable than before.
