Premium Suspension Kit for Ford Super Duty

If you’re ready to give your Super Duty the stance, clearance, and off-road capability it deserves, Rough Country’s 6-Inch Suspension Lift Kit is the upgrade that gets it done right. This isn’t just about fitting larger tires, though it’ll clear up to 37s with ease, it’s about transforming how your truck looks, rides, and performs both on and off the pavement. At the heart of this kit are Rough Country’s beefed-up radius arms. These things are no joke, each one weighs in at 27 pounds and is built to handle real abuse, with vibration-dampening Clevite rubber bushings and a design that bolts straight into factory locations. That means easier installation and geometry that stays true to OEM specs, so you don’t sacrifice ride quality just to run a taller stance.

Lifted Coil Springs with Rear Blocks

Up front, you get lifted coil springs that offer predictable handling and support. In the rear, fabricated anti-wrap lift blocks replace the factory ones. These aren't just there for lift, they're designed to reduce axle wrap and binding, keeping your drivetrain running smooth under heavy torque. Whether you're towing, hauling, or trail crawling, this kit gives your truck the balance it needs to stay confident and composed. Best of all, installation is completely bolt-on, no cutting or welding required. And with your choice of Rough Country’s N3 performance shocks and a limited lifetime warranty on hard components, you’re backed up for the long haul.
