TNT Duramax Drop-In Performance 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. From a responsive 2004.5–2010 LLY/LBZ/LMM tow rig to a big-power 2017–2023 L5P/L5D build, this collection brings together every drop-in Duramax turbo TNT builds — Canadian-built turbo solutions designed for real-world diesel performance across every generation.

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.

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.

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. See the LML turbo overview or LML vs LLY/LBZ/LMM.

L5P/L5D Duramax Turbo Upgrades (2017–2023)

The 64/67 configuration is built for owners who prioritize towing performance, daily drivability, fast spool-up, and lower EGTs under load — an excellent balance of airflow improvement and street-friendly response. The 67/67 configuration is engineered for owners who want additional airflow capability and higher horsepower potential, ideal for builds planning larger fueling upgrades and more aggressive tuning while still retaining strong towing capability.
