Description

Order your upgraded turbo today! The L5P Stealth STR is the best replacement turbo for your stock 2020, and 20216.6L L5P Duramax. While capable of providing enough airflow to support up to 650RWHP, this stock-appearing unit still lights quick and is great for daily driving, towing, and putting Powerstrokes in their place.

If you have been looking at other "64mm", "Stage 1", or stock turbo replacements this is a game changer. This turbocharger does not need custom tuning or other upgrades to get superior performance. Box programmers and inline modules work seamlessly with the L5P Stealth STR.

Don't be fooled by the imitators! We've been building custom turbos and providing custom tuning for more than 15 years. We were the first custom tuners to work on the L5P Duramax platform and know exactly what these trucks need to go to the next level.

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.
