Considering there's no power added for the 17s yet just the 30hp delete tune they havnt been stretched yet. But if like the 15-16 trucks- overdrives will be burned out quick after 550rwhp. The 11-14s are good but ford pulled one OD clutch out of 15-16 to cool them down as the 6Rs will run 185-200 normal it hurt them pretty good.
