Features to know about

Stay Level, Stay in Control

Heavy loads can turn your Ford Super Duty into a handful fast, sagging in the back, floating in the front, and feeling unpredictable around corners. This air suspension system steps in where your factory springs give up. With up to 5,000 lbs of leveling support, you can tame squat, improve steering response, and restore the confident ride your truck had when it was empty. The double-convoluted design absorbs road shocks, softening contact between your axle and frame to prevent bottoming out. This basic system comes with everything you need to manage what you're hauling—compressor, air bags, and controller— so you'll stay level, stable, and in control whether you're hauling construction gear or towing the family camper.

Adjust Side to Side When Loads Shift

Loose materials like gravel, mulch, or firewood can shift to one side, especially on hills, curves, or uneven terrain. When this happens, your truck can start to lean, throwing off your handling and putting strain on your suspension. With independent air bag control, you can quickly adjust pressure side-to-side to bring things back to level without unloading or rearranging cargo. It's one of those features you don't think about until the load shiftsand you're glad you have it.

Installation That Doesn't Waste Your Weekend

Bad installs can turn a good upgrade into a weekend-wrecking headache. That's why this system is designed for clean installation right from the start. You get everything you need from vehicle-specific brackets, pre-installed push-to-connect air fittings, and pre-assembled wiring harnesses to cut out the guesswork and avoid fighting spaghetti wiring after dark. The quick mount system for the compressor and controller means no drilling required, helping most installs wrap up in hours, not days. No matter if you're installing it yourself, or handing it off to a shop, the end result feels clean, strong, and factory-ready, not hacked together.

Built Tough for Trucks That Actually Get Used

Rough roads, salty winters, muddy job sites—this system was built to survive them all. The waterproof, debris-resistant compressor shrugs off the elements so you can count on it work wind, rain, or shine. Twin heavy-duty air bags feature one-inch thick, corrosion-resistant end caps and 20 support wires for maximum strength under load. If you're towing with a fifth-wheel hitch or hauling a heavy bed full of gear, the sealed wiring harnesses and military-grade solenoids keep everything running clean and reliable. This isn't weekend gear for show trucks—it's a real-world system for trucks that don't quit when the weather or the payloads get serious.
