When I first put big tires (bald mall terrains) on my jeep I ran rancho 4" coils in front (I believe that's what they were) and V8 ZJ springs in rear with a spacer, was ok but after a trip to gulches i hated how tall and unstable it was. Swapped front out for the V8 ZJ and moved spacer from back to front to level it out and it was great netting me about 2.5-3" probably over stock. It rode great and was stable enough I could haul *** through curvy roads without ever feeling tippy, even with no front stabilizer.
Look into some OME or rough country 2.5" springs and I bet you'd be a lot happier with it.
