2017-2022 Duramax L5P Calibrated Power Stealth 67G2 Turbocharger (DM1JK1070303000)

The L5P Stealth 67G2 is the best drop-in turbo ever bolted to the 2017, 2018, 2019 6.6L L5P 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.

Your truck is going to experience increased performance across a wide operating range due to our HFV assembly, oversized turbine wheel, and billet compressor wheel. Built from brand new parts, this turbocharger won’t require a core charge. The optional actuator is pre-calibrated and the entire turbo comes ready for installation. You should strongly consider custom tuning to go with this turbocharger upgrade. Deletes are not required.

This Turbo is Designed for you if ...

• Already have, or also installing custom tuning
• Daily drive your truck
• Have Reliability and Performance as top priorities
• Tow with your truck
• Want More Power when you need it, but still have excellent street manners!

Do you need an Actuator?

 If you're wondering whether or not you should buy an actuator to compliment your Stealth turbo, allow us to share our thoughts.  The 2017-2023 6.6L Duramax turbo actuator has a very low failure rate in the field.  The fact that it's well-cooled and not in close proximity to the hot parts of the turbo means that it's out of harm's way.  Unless you're experiencing codes that indicate actuator issues or know for a fact that your actuator is somehow damaged, we would suggest saving your money and retaining your factory actuator.
