Take Full Control Of How Your Truck Rides

If you're ready to push your Super Duty to the next level, the ICON Stage 8 4.5" Suspension System gives you more than just a lift, it gives you control. Whether you're towing through the mountains, cruising the highway, or crawling through rugged terrain, this system adapts to how and where you drive. At the heart of it is ICON’s Intelligent Control (IIC) and CDEV shock technology, which allows you to adjust compression settings right from the cab. The system actively reacts to changing conditions in real time using onboard sensors, which means your truck isn’t just lifted, it’s smart. You’ll get smoother travel over uneven roads, more predictable handling under load, and the confidence to go wherever the job or trail takes you. Paired with 4-link front suspension, a steering stabilizer, and ICON’s signature dual rate coil springs, this setup doesn’t just improve the look of your truck, it transforms how it feels behind the wheel. If you want total ride control and rugged performance, this kit checks every box.

Advanced Suspension Technology Built For Hardworking Trucks

The ICON K64548 Stage 8 Suspension System is engineered specifically for 2023-2025 Ford F-250 and F-350 4WD diesel trucks, offering 4.5 inches of front lift and a serious upgrade in dynamic handling. The dual rate coil springs provide improved ride quality across a variety of surfaces, while the rear receives heavy-duty lift blocks and extended U-bolts for proper stance and support. ICON’s 2.5 Aluminum Series shocks with CDEV (Compression Damping Electronic Valving) technology are the centerpiece of the system, offering real-time, computer-controlled damping adjustments based on G-forces and chassis movement. These shocks work with the ICON Intelligent Control module, which actively monitors your driving input and terrain to optimize compression settings automatically. The 4-link front suspension enhances articulation while maintaining proper caster geometry throughout the travel range, improving high-speed stability and off-road maneuverability. A dropped track bar bracket corrects steering geometry, and the adjustable track bar allows for precise front-end alignment. With stainless braided brake lines, hard anodized shock bodies, and fully rebuildable components, this system is built for both performance and long-term durability.
