Upgrade your turbo today! The L5P / L5D Stealth 67G2 is the best drop-in turbo ever bolted to the 2017, 2018, 2019 6.6L Duramax. While capable of providing enough airflow to support up to 800 RWHP this stock-appearing unit still lights quickly and is great for daily driving, towing, and maximum performance.

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.
