well... since you have an air tank, compressor, solenoids etc allready in there.. im going to recomend you to call ridetech and get a full suspension package with a arms, shockwaves and swaybars....
they have really transformed airsuspension from just level controll to actual well cornering setups.. you get great ride quality.. their awesome shocks (and they really do have great shocks) and highly progressve springrates allong with a fool proof.. install in a weekend setup that works...
