LLY, LBZ, LMM, Stealth Mach 2 Turbo (2004.5-2010)

Fly Under the Radar! With the Stealth Mach 1 2004.5-2010 Duramax Turbo Upgrade.

Building this line of Stealth's meant designing a turbo that would be safe to tow with, fun to drive every day and perform at competitions. If you think street-able, clean, stock-appearing power is cool, then this is the turbo for you!

The Stealth Mach 2 takes a stock appearing LLY/LBZ/LMM turbocharger and overhauls it to be the Ultimate Duramax VVT drop-in. This means your new turbo will spool-up quickly, feel responsive, and most importantly will move for air into your engine! That means more top-end power without sacrificing driveability.

This turbocharger features HFV technology! HFV or High Flow Vane technology is our proprietary customization of the variable vane cage and nozzle ring assembly. This advancement allows the use of a larger turbine wheel for maximum high-load efficiency. Stealth turbos featuring our HFV upgrade are capable of producing more power, spooling up quicker, and managing EGTs better than those limited with factory nozzle rings.
