Air down a little when running gravel roads and stuff. It really makes a difference. New shocks will help. I think I heard somewhere that lift shackles make for a rougher ride? I could be wrong. Mine has worn out saggy 3.5 inch lift springs and rides way better than my buddys TJ with 2.5 inch lift springs... My ride also got a lot better when I ditched the track and sway bars.
