Smeding Diesel 2020-2025 Chevy/GMC 2500/3500 L5P Duramax Max Flow Turbo Kit
When a standard S300 swap isn't enough L5P, this is the top of the range: Smeding's Max Flow package for the 2020-2025 L5P Duramax, built to move serious air for high-horsepower builds.
It's a complete high-flow bundle engineered to bolt onto the L5P platform for maximum airflow and power potential.
Requires custom tuning. As a conversion away from the factory variable-geometry turbo on an emissions-equipped truck, this is intended for off-road and competition use where permitted — check your local regulations before installing.
This is a big-power component — call us to confirm it's the right fit for your build before ordering.
Assembled in the USA and high-speed balanced before it ships. 1-year unlimited-mileage warranty.
Not sure which wheel fits your build? Call 636-429-7020 or email [email protected] and we'll match the turbo to your fueling and goals the first time.
