I'm looking into and air lift suspension system for my 04 250 any good idea's

 

Are you looking to be able to adjust it on the fly? If so you will need at least a compressor and a tank would be a good idea to have as well. I went with Firestone's Ride Rite bags w/ their dual switch & combo gauge controller. I built the rest of my air system piece by piece with a Viair 480c and an 8.5gal tank. I also just bought some 2" spacers for the airbags so I don't have to run as much pressure in them to get them up.

I guess it depends on how much lift you are trying to accomplish?
