4-Link Lift System Upgrade for Diesel Super Duty 4WD

If you're ready to take your Super Duty’s capability and stance to the next level, Rough Country’s 6-Inch 4-Link Lift Kit is the kind of upgrade that makes an instant impact. Designed specifically for 2017–2022 Ford F250 and F350 6.7L Powerstroke 4WD trucks, this kit doesn’t just add ground clearance—it transforms the way your truck looks, handles, and performs on and off the road. At the heart of this system is the 4-link suspension design, replacing your stock radius arms with fixed upper and adjustable lower control arms. This setup isn’t just for show—it greatly improves wheel travel and steering geometry, offering a noticeable improvement in handling and articulation, especially when tackling rugged terrain. Caster angles stay right where they should, even at full lift, which means you retain predictable, factory-like drivability.

Complete with High-Quality Components

The kit also includes a set of heavy-duty lifted coil springs and ultra-strong fabricated rear blocks. These aren’t your run-of-the-mill cast blocks; they’re specifically designed to prevent axle wrap, a common issue when lifting heavy-duty trucks. That means better traction, smoother take-offs, and more stable towing and hauling. Stainless steel extended brake lines and brackets come standard too, ensuring everything works in harmony with your lifted suspension setup. Rounding out the package are Rough Country’s N2.0 nitrogen-charged shocks. Whether you're cruising down the highway or bouncing over backcountry trails, these shocks balance comfort and control with a valved design tuned for both street and off-road performance. Best of all, installation is bolt-on with no cutting or welding required, making it a manageable weekend project for the DIY-savvy truck owner.
