Just the SC system. This is one of the most cost efficient ways to sc one these trucks. Find a decent kit for sale and whatever it's missing can be found here

As for Procharger I am not a fan. Fit and finish is terrible on their kits as is customer support. And for me the Procharger just to slow to make boost in a 6000lb truck. But these are my opinions based on what I have seen and read about.
