17+ Ford F450/550 4-Link Rear Kit

08-16 Ford F450/550 4-Link Kit

The Ford F-450 and F-550 Chassis Cab trucks are everywhere. They are used as ambulances, service trucks, tow trucks, and more. Despite their popularity, the factory suspension can often leave a lot to be desired in terms of capability and ride comfort. That is why Kelderman introduced the 4-Link Rear Air Suspension for Ford F-450/550 Chassis Cab vehicles. Our strong 4-link suspension design completely removes the factory leaf spring suspension in favor of a full air ride suspension. Kelderman's design allows for the use of four industrial strength air bags (two per side) to increase payload & towing capacity, as well as improve the ride quality. If you spend a lot of time in these trucks, you certainly know how rough they can be traveling down the road. You don't have to suffer anymore thanks to a
Kelderman air suspension system. By eliminating the stiff leaf spring suspension you will no longer have a harsh, rigid ride quality. Enjoy the benefits of air suspension when using one of our optional, self-leveling air control packages that will allow you to lower the suspension 3.5-4 inches to help load items on the bed of your truck or when hooking up to trailers. At the flip of a switch, the truck will adjust for any weight to return to the original ride height. These optional air control packages also adjust to weight automatically. Just hook up to your trailer and the control system will sense a change in weight and add air into the system to avoid any squatting while loaded.Take your work truck to the next level with a Kelderman 4-Link Rear Air Suspension System!

Front Kits

2011-2016 Ford Super Duty Front Air Suspension

2017+ Ford Super Duty Front Air Suspension


A Kelderman 2-Stage Front Air Suspension is an excellent addition to a Kelderman 4-Link Rear Air Suspension on your Ford Super Duty 4x4 truck. Our 2-Stage Front Air Suspension eliminates the factory front coil spring suspension and allows the front of your truck to ride on full air suspension. The Kelderman 2-Stage Front Air Suspension System includes upper and lower air bag mounting brackets, industrial strength air bags, and upgraded Rancho 9000 adjustable shocks. The combination of adjustable air suspension and adjustable shocks lets you dial in the ride quality of your truck to exactly where you would like. These 2-Stage Front Air Suspension kits are also available in a leveling kit variety to help eliminate the rake of your Ford truck. If you are using your truck with a heavy front bumper or a heavy snow plow, these front kits are perfect for carrying the weight. You'll never have to worry about any sagging from the front suspension, simply add more air to the 2-Stage Front kit until it's back to the proper 'ride height'. When equipped with our 4-Link Rear Air Suspension and an optional, electronic air control system, you can raise or lower the truck 3.5-4" above AND below the designed 'ride height' setting.
