I realize this is a expo forum, not really a truck forum but i was hoping there would be somebody with experience with lift kits for full size trucks. i want to do a 4" inch lift kit on my 2003 7.3 super duty, i want it to be all leaf. i've heard good things about ICON and was curious if the 5" excursion lift kit would give me 4" of lift on the super duty. i think all parts are the same and its sold as a package which saves me the trouble of piecing it together. any pros/cons/experience with ICON for an expo vehicle?
