4-Link Lift System for 6.7L Powerstroke Trucks

If you're ready to take your Super Duty to the next level, literally and figuratively, the Rough Country 50720 6-Inch 4-Link Lift Kit is a game-changer for your 2017–2022 Ford F250 or F350 with the 6.7L Powerstroke. This isn’t just about fitting bigger tires or gaining a taller stance. This is about serious upgrades in ride quality, handling, and suspension geometry, especially for those who push their trucks on- and off-road. The heart of this system is the 4-link setup. Swapping out the stock radius arms for Rough Country’s fixed upper arms and adjustable lower arms gives your front suspension better control over axle movement, reduces binding, and improves wheel travel. It’s a noticeable difference when you’re navigating uneven trails or hauling heavy loads. Combined with the included radius arm drop brackets, you get proper caster alignment, crucial for preserving that factory-like handling even with the added lift.

Heavy-Duty Construction & Design

Up front, heavy-duty coil springs provide the lift while still maintaining ride comfort. Out back, Rough Country includes fabricated anti-wrap lift blocks that do more than just boost ride height, they also help eliminate axle wrap, which is common on lifted trucks and can seriously impact drivability. These blocks are engineered for strength and longevity, making them ideal for anyone who works their truck as hard as they play. Also included are extended stainless steel brake lines and brackets to maintain proper brake function with the increased ride height. To top it all off, the kit comes with Rough Country’s Nitrogen-charged N2.0 shocks, offering a great balance between off-road responsiveness and smooth highway ride quality. Best of all, this is a bolt-on install. No cutting, welding, or major modifications needed, just the right tools and a few solid hours in the garage.
