<font color=blue>If you're going with 4" of spring lift, your driveline/steering linkage will require modification. The most you could "spring-up" without extensive/expensive driveline/steering mods is prob 2.5"...
Then, get a 1" body lift. You can then maybe
avoid lots of expensive mods, plus your ride will be better than on 4" springs..
