Thanks Robbie...I will have a look at that site, but as you can see I have lowered a couple of rides in the past and thought, go with the site that seems to know.
you only need a 4in lift to fit 35s on the F-150. Fabtech, Superlift, Procomp all are great lifts...Pretty easy to install I helped my buddy lift his 03 Crewcab f-150 6in with a procomp kit and we had it done in a day.
My buddy has a F150 with a 3" body and he had 35s on it. It rubbed just on the inner fender plastics. He later put 33s because hes cheap. And now it doesnt rub.
