Fits: 2011 thru 2016 Chevy Silverado/GMC Sierra 2500HD/3500HD LML Duramax Diesel

The Stealth Mach 1 Hybrid is a specialized stock appearing, direct replacement for your LML Duramax. Specifically designed for sled pulling and compound turbo applications due to its unique configuration. This turbo features all the guts of Stealth's most powerful 67mm Mach 2 turbo, but with the slight tweak of utilizing the smaller 63mm Air Grabber compressor wheel. This was done to create the most optimized primary compound turbo offering on the market. This turbo is also a great option for those limited to a 64mm compressor wheel due to competition regulations and who want to make the most out of their top-end performance.

While upgrades found in the Mach V such as HFV (High Flow Vane technology) & an extra-large turbine wheel are not ideal for low end power or spool up. The improvement in flow that they do offer can directly result in an increase in top-end performance. This increase in flow is also ideal for passing as much of the additional exhaust gas energy as possible on to the turbine of a secondary turbo in a compound setup. Further helping to increase compound turbo setup efficiency and performance. Not only that but increased exhaust side flow from upgrades such as HFV, an upgraded turbine wheel, and ported exhaust housing can significantly help in managing EGTs while under load.

The unique advantage of this turbo's design cannot be understated. Aided by insight from the tuning experts DuramaxTuner’s experience with the LML Duramax platform and how it responds to tuning adjustments, changes in airflow, and increased power was a crucial component in building you the perfect primary compound turbo.
