"hackshack.com" makes a kit dont know exactly how much it is I pieced my kit together and saved about 500.00 you will want to have all wheel independent that way you dont get really bad body roll around corners another thing is air ride is for cars to go low right well I put the kit on and had to cut my rear brackets because it didnt go very low but got hell of lift so I cut 3" off the back brackets it can brake a cylinder in half if you bounce it around really fast but it does work and it gets hella low just some things to let you know but I put air on my eclipse and it rides just fine any questions email me I will be more than happy to help
