2006-2007 Duramax Twin Turbo Kit (424402)

Industrial Injection's twin (compound) turbo kit for the 2006-2007 6.6L LBZ Duramax stacks a larger high-pressure charger on top of a big atmospheric secondary for serious airflow — built for trucks chasing big horsepower, sled-pull, and race duty rather than daily towing. Expect a wide, hard-hitting powerband when paired with the proper fuel system and tuning.

Includes all piping, brackets, hardware, and oil/coolant lines required for installation on a built-up LBZ platform.

• Compound turbo arrangement sized for high-horsepower applications
• Large secondary charger for sustained top-end airflow
• Complete kit — piping, brackets, hardware, and lines included
• Built for race, sled-pull, and aggressive street builds

• Custom tuning and supporting fuel system (lift pump, larger CP3/injectors) required.
• Not intended as a tow-only setup — see the Towing Compound Kit (424403) for that use case.
