I have a ford quality steel pulley and roush belt brand new that I don't need. I just put one on my car and a buddy changed his mind and left me with this spare. The belt is a smidge shorter than the stock belt and a little higher quality. It does not come with a Tune. I'm going to the dyno for that. I'll include the sealer for the snout and the instructions I used which are the best I have seen. I did not have to open the acess hole to install this. All you need is two small bottles of the supercharger oil from Ford to re-fill. I am going to eBay it if no one here is interested. $210.00 out the door. PM me.
