2017-2019 Duramax Stealth Mach 2 67 Turbocharger (DM1JK1070303000)

Fits

High Flow Vane technology is Calibrated Power's 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 HFV upgrades are capable of producing more power, spooling up quicker, and managing EGTs better than those limited with factory nozzle rings.
