Fitment: 2020-2023 GM 6.6L DURAMAX L5P
Order your upgraded turbo today! The L5P Stealth STR is the best replacement turbo for your stock 2020, 2021, and 2022 6.6L L5P Duramax. While capable of providing enough airflow to support up to 650 RWHP, this stock-appearing unit still lights quickly 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. Airflow to support 650HP
Up to 600 RWHP with stock emissions equipment and basic supporting mods
