It depends. They have a stage one, stage two, and a stage three. I could be wrong, but I think the stage one has the Roush suspension and the body kit, the stage two has the suspension, body kit, cold air intake, mass air meter, and a short throw shifter, and the stage three has all of the above plus a supercharger and a few other goodies. Once again, I'm not sure, but if my memory serves me, that's pretty close. I have always liked Roush, since I laid eyes on my first Roush F-150. It was bleu with white racing stripes, extended cab, the famous extremely oversized and overpriced Roush rims, leather interior blah blah blah. I only wish I could afford the stage 3.
