Description

There's nothing better than upgrading your parts instead of just replacing them. That's why the Stealth STR is the perfect upgrade for your 2017, 2018, or 2019 Chevy Silverado/ GMC Sierra 2500/3500 L5P Duramax. It combines the affordability of a stock turbo replacement with some of the best upgrades you can get in a drop-in L5P charger. Whether you’re looking for more power or simply a do-it-all kind of turbo with some added durability the STR delivers.

  • Have a Box Tuner or Custom Tuning installed on your truck
  • Want to make 625+rwhp or less

  • Need a new replacement turbo for your L5P

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 L5P 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.
