Smeding Diesel S400 Second-Gen Turbo Kit with Manifold (2007.5–2012 6.7L Cummins) Built for Towing, Racing, and Everyday Driving The Smeding Diesel S400 Kit transforms your 6.7L Cummins into a truck that’s not only more powerful, but more enjoyable to drive every day. Whether you’re towing heavy, racing at the track, or just running errands, this kit delivers performance, reliability, and the iconic second-gen Cummins sound that enthusiasts crave. Why It’s Great for Every Driver Towing Made Easier The second-gen turbo location and S400 airflow design help keep EGTs lower while hauling. More airflow under load means stronger pulls on grades and reduced turbo stress. Select the right housing/turbo combo to maximize torque and drivability on long trips. Race-Ready Performance Larger billet and cast wheel options (S467, S472/87, SXE-R) deliver serious horsepower potential. Quick-spool turbine housings give you instant throttle response with top-end airflow to back it up. Per
