The Kelderman 4-Link Rear Air Suspension for 2017-2022 Ford F-250, F-350, and F-450 4×4 pickups replaces the factory rear leaf spring suspension with a true air suspension system designed to improve ride quality, suspension performance, and overall driving comfort.

Unlike traditional airbag helper systems that work alongside the factory leaf springs, Kelderman’s 4-Link system eliminates the leaf springs and replaces them with a fully engineered suspension built around large, semi-style air springs and heavy-duty trailing arms. The result is improved ride quality and greater control, whether the truck is loaded or unloaded.

The system can be paired with several air control options, including fully automatic mechanical self-leveling controls. This will allow the suspension to automatically adjust to the weight of your trailer, cargo, and more. With the push of a button, you can lower the rear suspension down approximately 4″ for an easier time hooking up to trailers or loading items into the bed. One more button push, and it will go right back up to ride height. The Mechanical Air Control System can utilize the in-cab upfitter/auxiliary switches for a clean, factory installation.

Whether your truck is used for towing, hauling, daily driving, or long-distance travel, the Kelderman 4-Link Rear Air Suspension delivers a smoother, more controlled driving experience while maintaining the capability expected from a Super Duty pickup.
