Collection: 2006-2007 GM 6.6L LBZ DURAMAX

The LBZ engines have undergone several internal upgrades, including lower compression and a taller deck height. These upgrades allow the engine to handle increased boost levels, resulting in additional power, making it an excellent platform for building a high-performance vehicle. We offer various proven power combinations based on your specific requirements for your truck. If you are uncertain about which parts are suitable for your needs, feel free to contact us, and we will be more than happy to help. The products in this section are intended for use with 2006 and 2007 (classic body style) 6.6L GM Duramax equipped trucks unless stated otherwise. To confirm whether your engine is an LLY or LBZ, use your VIN. Check the 8th digit in the VIN number: If it's a D, you have the LBZ engine; if it's a 2, you have the LLY engine.
