The S475 Dodge Ram 6.7L Cummins 2nd Gen Turbo Swap Kit is a great option for the person who is looking to build max power with a single turbocharger. The S475 is equipped with a large 75mm compressor wheel. This turbo is normally used in race applications only. It’s really only good at full throttle! This is a complete kit that comes with everything needed for a nice clean install.
