Description

The Industrial Injection S475 Turbo Swap Kit converts the 2003-2007 5.9L Common Rail Cummins to a 2nd-gen-style single S475 setup. The S475 is an S400-frame turbo built for owners chasing big numbers on a still-buildable platform, from mild-aggressive street to full race.

The kit ships as a complete bolt-on swap — turbo, custom S&B-designed intake, mounting hardware, gaskets, and clamps — and gives you the choice of .90, 1.00, 1.10, or 1.25 T4 turbine housings to match how you'll drive the truck.
