Description

The LML Stealth Mach 2 (67mm) presents a stock-like appearance while serving as a direct replacement for your 2011, 2012, 2013, 2014, 2015, and 2016 LML Duramax. Its enhanced billet compressor and oversized turbine wheel are expertly paired with our custom-cut compressor cover and exhaust housing for optimal performance.

Featuring our exclusive HFV technology, this turbocharger boasts a proprietary customization of the variable vane cage and nozzle ring assembly. This innovation enables the utilization of a larger turbine wheel, ensuring maximum high-load efficiency. Stealth turbos equipped with our HFV upgrade outperform those constrained by factory nozzle rings, delivering increased power, quicker spool-up times, and superior management of exhaust gas temperatures (EGTs).

Your truck is poised to experience heightened performance across a wide operating range, thanks to our HFV assembly, oversized turbine wheel, and billet compressor wheel. Crafted from brand-new components, this turbocharger eliminates the need for a core charge. The optional pre-calibrated actuator simplifies installation, making the entire process hassle-free. Custom tuning is highly recommended to fully optimize the performance of this turbocharger upgrade. Deletes are not required. With our Custom Emissions Equipped Tuning, we’ve achieved up to 650 RWHP when pairing this turbo with our custom tuning solutions.
