I have a 98 2wd 5.4 Ed Bau Expedition with air suspension and have just gotten serious about lifting it. I have seen the 3.5 inch fabtech spindle kit, the rcd 6 inch and of course 3 inch body lift. If anyone has any experience or knowlege in the subject it would be greatly appreciated!

 

From what I understand the rear airlift is a problem with most lifts.
