i can get 3" coils in, easily without the compressors. the compressors scare a lot of people, and i understand why! down the road when you run 5.5" coils, you wont have a choice, but with sub 3" coils , you have the choice! stockers come off waaaaaaaaaaaaaaaaaaaaaaaay easy.
remove wheels and disconnect the trackbar, shocks, and swaybar. with the jeeps body up on jackstands, you should have enough room to lift one side of the axle up, drooping the other down far enough to sneak the coil in. watch out for brakelines!
the more lift in the coils, the harder it can be, but with your setup, it should be cake!
if you ever strip a brake line flare nut... use a pair of vice grips, the flare nut is soft, and the aggressive jaws of the vice grips bite right in! but yeah, use the right size wrench to get a nice and snug fit at the very least!
