Engineered for Real-World Adventure and Workhorse Demands
The ICON 4.5″ Stage 8 Radius Arm Lift Kit with Leaf Springs is built for Super Duty owners who expect more from their suspension, whether they’re hauling heavy gear, tackling job site terrain, or pushing their truck through rough backcountry trails. Designed specifically for 2023-2026 Ford F250 and F350 4WD diesel models, this system offers a serious upgrade in ride quality, wheel travel, and control. It pairs ICON’s proven dual-rate coil springs with their finely tuned 2.5 Aluminum Series shocks, delivering a ride that feels stable and predictable across gravel, pavement, or uneven ground. The inclusion of ICON’s CDE Valve and Intelligent Control (IIC) system gives you the ability to adjust compression damping on the fly, reacting in real time to changes in terrain and vehicle movement. It’s the kind of setup that responds to you, not the other way around.
Stronger Components and a Smoother Ride with Smarter Control
The Stage 8 system also features fabricated radius arms that don’t just improve strength and ground clearance, but also provide better caster correction and tire clearance. Rear leaf spring expansion packs deliver two inches of lift while keeping ride comfort intact, especially under load. Front and rear wheel travel is significantly improved over stock, which you’ll notice right away whether you’re crawling over rocks or pulling a trailer down a washboard road. ICON’s track bar and centerline steering stabilizer setup helps tighten up steering feel and minimize bump steer. Installation is bolt-on and straightforward, with components that are built to last and backed by ICON’s lifetime guarantee on springs and fabricated parts. If you’re looking to build out your rig with premium suspension performance and full adjustability, this kit checks every box.
