1999-2004 FORD F-250/350/EXCURSION 4X4 5-6" FRT

Take your Super Duty to the next level with the help of a 5-6” 4-Link Air Suspension Lift Kit. Designed for 35” tires, this lift kit removes the old leaf spring setup from your truck in favor of a fully fabricated, 4-Link Air Suspension system. This kit includes adjustable trailing arms, knuckles with bushings, upper and lower air bag mounts, industrial strength air bags, panhard bar w/bushings, shock mounts and more! Make your truck different from the rest with a completely adjustable air suspension lift kit. This lift kit is capable of lowering from its 5-6” ride height to a 1” lift when fully deflated and can inflate up to a 10” lift. Don’t worry about having a lifted truck that can’t tow anything…thanks to our industrial strength air bags, a Kelderman lift kit can tow everything you want and then some! All you need to do is throw more air in the bags and go!

By getting rid of the rough riding leaf springs you will improve the ride comfort of your truck and have the best possible ride quality from a lifted truck. Many optional air control systems are available for all Kelderman products, so find out which system works best for you here. We recommend the Hadley SAMS 4X4 Electronic Air Control System which can control a front and rear air suspension lift kit with a touchscreen controller within the cab. Fox shocks are also available for Kelderman lift kits, as well as custom Kelderman billet shock clamps.
