If you want to be the tallest Super Dut around town, you've come to the right place. The legendary 12-14" 4-Link Air Suspension Lift Kit is just what you need to set your truck apart from the rest. Capable of running 40" tires or 44" tires with fender cut outs, you'll be sure to have the baddest truck around. Should you happen to run across another lifted Super Duty and wish your truck was just a little bit taller...just push a button on the optional air control systems and your truck can inflate even higher to an 18" lift. That's right...this isn't your average lift kit. The Kelderman 12-14" Air Suspension Lift kis is fully adjustable from an 8" lift, to the 12-14" ride height, and all the way up to a monstrous 18" lift kit. Convert your junk leaf springs over to a high quality air suspension to make your truck like nothing else around. This kit comes complete with adjustable trailing arms, upper and lower air bag mounts, industrial strength air bags, indexing ring, larger rear sway bar, sway bar end links, panhard bar and crossmember, brake lines, shock mounts and more. This kit is even availalbe in a single or dual rear shock mount configuration.
