Are you looking for a better ride AND better towing? That is exactly what a Kelderman 4-Link Rear Air Suspension provides. This kit gives you the best of both worlds by eliminating your factory leaf spring suspension and upgrading your Super Duty to a durable 4-Link Rear Air Suspension System.
This kit includes upper and lower air bag mounting plates, industrial strength air bags, trailing arm mounts, adjustable trailing arms, axle clamps, rear crossmember, adjustable panhard bar, upgraded rear sway bar, sway bar end links, all required hardware, air line, fittings, and Schrader valve style inflators. The result is a dramatic change in ride quality with an increase in towing abilities. The industrial air bags found in our 4-Link Rear kits are similar to what you would see in a semi truck application. They are rated to more weight than your existing leaf spring suspension to make sure you can tow or haul whatever your Super Duty needs to do. Pair one of these kits with an optional, self-leveling air control system to give yourself onboard air. These kits can provide you with an onboard air compressor, air tank, leveling valves/sensors, dump valves, air dryers, and more. When properly equipped, you can hook your truck up to your trailer and it will briefly squat before returning to it's original 'ride height' position. Your 4-Link Rear Air Suspension is also capable of lowering close to 4" to save you time & effort while loading items in the truck bed, hooking up to trailers, and more.
You deserve a truck with suspension that can do it all. Don't settle for a heavy duty ride just because you need a heavy duty truck. Upgrade your Super Duty and your springs to a Kelderman 4-Link Rear Air Suspension today!
