TNT Duramax Turbo Upgrades

The TNT Duramax Turbo Upgrades hub is designed to help diesel owners compare True North Turbos options across every Duramax generation — 2004.5–2010 LLY/LBZ/LMM, 2011–2016 LML, and 2017–2023 L5P/L5D. Whether you need a responsive drop-in VGT turbo for an early truck or a big-airflow option for a newer L5P/L5D build, this guide connects the key products, articles, and resources in one place.

Black Sheep Industries builds True North Turbos for real-world diesel performance: towing, street response, airflow efficiency, lower EGTs, and long-term reliability. Instead of treating every build like a race-only application, TNT Duramax turbos are designed to match the way truck owners actually use their vehicles.
