Duramax LLY, LBZ & LMM Turbos

True North Turbos offers performance-focused Duramax turbocharger upgrades for drivers who want stronger towing performance, better airflow, lower exhaust gas temperatures, improved spool-up, and reliable street manners. Whether you're building a responsive 2004.5–2010 LLY/LBZ/LMM tow rig or upgrading a 2011–2016 LML Duramax with a 63.5mm drop-in turbo, this collection brings together Canadian-built turbo solutions designed for real-world diesel performance.

Every TNT turbo is designed, machined, assembled, and balanced in Canada by Black Sheep Industries. These turbochargers are built for Duramax owners who expect more than a generic replacement unit — they want quality, response, durability, and a turbocharger that can handle towing, daily driving, and performance use.

2004.5–2010 LLY/LBZ/LMM Duramax 63.5mm Drop-In VGT Turbo | 600–650WHP

The 2004.5–2010 LLY/LBZ/LMM Duramax 63.5mm Drop-In VGT Turbo is a direct-fit upgrade for early Duramax trucks, supporting 600–650WHP while improving airflow, spool-up, and towing response. It's built for owners who want a bolt-on turbo upgrade without giving up factory-style drivability.

2011–2016 LML Duramax 63.5mm Drop-In Turbo | 700WHP

The 2011–2016 LML Duramax 63.5mm Drop-In Turbo is designed for LML owners who want more airflow capacity, supporting up to 700WHP for towing-focused builds and higher-power street applications while retaining a straightforward drop-in installation.

LLY/LBZ/LMM Duramax Turbo Upgrades (2004.5–2010)

The 2004.5–2010 Duramax platform (LLY, LBZ, and LMM) is a popular upgrade path for owners chasing better towing response, improved airflow, and lower EGTs without moving into a full custom turbo setup. The TNT 63.5mm drop-in VGT turbo is built to bolt into the factory location, giving these trucks a meaningful power and drivability upgrade while keeping installation straightforward for a home garage or shop.

This platform benefits most from a turbo that spools quickly at low RPM, since these trucks are commonly used for towing, work duty, and daily driving as much as they are for peak horsepower numbers. For a deeper technical breakdown, see the LLY/LBZ/LMM turbo overview and LLY vs LBZ vs LMM comparison.

LML Duramax Turbo Upgrades (2011–2016)

The 2011–2016 LML platform supports more airflow than earlier Duramax generations, and the TNT 63.5mm drop-in turbo is built to take advantage of that headroom — supporting up to 700WHP while still functioning as a direct-fit replacement for the factory turbo. This makes it a strong option for LML owners who want more capacity for towing, tuning, and fueling upgrades down the road, without stepping up to a compound or custom big-turbo setup. See the LML turbo overview for the full breakdown.
