The Ford Superduty has been rocking stiff rear leaf springs since the dawn of time. Trucks today are doing more than their predecessors could ever imagine. While the capacities have increased, the ride quality hasn't had the benefit of vast improvements. The best way to make leaf springs better while not losing capacity; ditch the leaf springs! Kelderman had the same thought and made good on the idea with their 4-link rear air suspension.

Since the early 2000s, Kelderman has provided an innovative solution to improve your ride quality and increase your towing capacity on Ford Super Duty trucks. How do they do it? They take those leaf springs and throw them in the trash! Their 4-Link Rear Air Suspension completely eliminates the factory leaf springs and replaces the suspension with a durable, 4-Link design using industrial-strength airbags.

This Kelderman 4-Link Rear Air Suspension includes: upper and lower airbag mounting plates, industrial-strength airbags, trailing arm mounts, adjustable trailing arms, lower axle clamps, rear cross member, adjustable panhard bar w/ heim ends, accumulator tanks, and an upgraded rear sway bar assembly (F-250 & F-350 models only). This kit will take the harsh bounce out of the truck that typically comes with the leaf spring design. This kit will include a 'manual fill' air control package that provides you with the necessary air line, fittings and a Schrader valve to inflate the kit to the 'stock ride height'.

Pair the 4-Link Rear Air Suspension with one of the Kelderman self-leveling air control systems and your Super Duty will automatically adjust to the weight of your trailers. With the flip of a switch, the 4-Link Rear Air Suspension is capable of lowering 3.5-4" below the designed 'ride height' to save you time hooking up to trailers or make it easier to load items into the truck bed. Take your Super Duty suspension up a notch with an upgrade to a Kelderman 4-Link Rear Air Suspension today!
