Whether you're daily driving, towing heavy, or tackling rugged trails, this system keeps your F-250 or F-350 planted and predictable. The included dual rate coil springs are specially tuned to provide 4.5 inches of lift while maintaining comfort and stability, even when the road disappears.

You’ll feel the difference right away, from reduced body roll to better control over bumps, dips, and uneven ground. With adjustable compression damping and support for ICON’s Intelligent Control system, this kit adapts with you, on the fly, in real time. It’s everything you need to turn your Super Duty into a more capable, more enjoyable truck on or off the pavement.

Engineered Suspension Performance Built For The Real World

ICON put serious engineering behind this Stage 8 suspension kit to give your F-250 or F-350 a balance of lift, control, and long-term durability. At the heart of the system are dual rate coil springs designed to deliver consistent lift and enhanced ride dynamics under varying loads and terrain conditions. The 2.5 Aluminum Series remote reservoir shocks come pre-tuned for the Super Duty chassis and allow for extended damping control while keeping shock temperatures cooler under off-road stress. Integrated CDE Valve technology allows for in-cab adjustment, giving you the freedom to fine-tune ride stiffness without ever stepping out of the truck. When paired with ICON's optional Intelligent Control module, the system actively monitors chassis movement and road input to make real-time adjustments. This helps maintain optimal shock performance whether you’re crawling over rocks or cruising down the highway. Fully rebuildable and re-tunable shocks ensure long service life and future customization options. Stainless steel braided brake lines and heavy-duty radius arms round out the kit, offering improved braking response and front-end strength to match the lift.
