One can just remove stock leaves to get the desired ride, longer leaves in front as has been mentioned before softens ride, Kelderman has air ride kits that can give one ideas for making your own. For occasional use w/ an electric compressor, install a shop air fitting(schrader) to fill up bags if they get totally deflated, or for working on system. I made my own parallel 4 bar system using trailer torque rods, reasonable price, 2 bags off a semi 4 bag system. http://rides.webshots.com/album/581681868MDNTHo
