Push The Limits Of What Your Super Duty Can Do

If you want to transform your Super Duty into a truck that handles anything you throw at it, the ICON Stage 8 4.5" Lift System with expansion packs is exactly what you need. This setup not only gives you a taller stance but also unlocks the ability to run larger, more aggressive wheel and tire combinations without sacrificing drivability. Whether you are towing down the highway, hauling heavy loads on the job site, or blasting down washboard gravel roads, the dual rate coil springs and tuned 2.5 Aluminum shocks deliver a smooth, controlled ride. With leaf spring expansion packs adding two inches of rear lift, you get improved ride quality along with better small bump absorption. The CDE Valve technology gives you the ability to adjust compression damping right from inside the cab, while the ICON Intelligent Control system actively makes adjustments in real time. That means the truck responds instantly to changes in terrain, offering stability when cruising pavement and confidence when you drop into rough off-road trails. If you want the perfect balance of comfort, capability, and control, this system delivers in every category.

Advanced Suspension Engineering For Superior Ride And Control

This Stage 8 kit is built with serious engineering to optimize both on-road and off-road performance for 2023-2025 Ford F-250 and F-350 Super Duty trucks with gas engines. At the core are ICON’s dual rate coil springs, which balance soft initial travel for comfort with a firmer rate during compression to prevent bottoming out. The 2.5 Aluminum Series shocks with remote reservoirs feature ICON’s CDE Valve technology, allowing you to make ten levels of compression damping adjustments from the cab. Paired with the Intelligent Control system, these shocks actively adapt in real time by monitoring chassis movement and G-forces, giving you a ride that constantly adjusts to conditions. The 4-link design eliminates binding during articulation and maintains proper caster, while the adjustable track bar fine tunes axle alignment for sharper handling. The system also includes stainless steel braided brake lines, a 2.5 Centerline steering stabilizer with piggyback reservoir, and corrosion-resistant components designed for long-lasting durability. Every part of this kit is fully rebuildable and re-tunable, making it a true investment in your truck’s long-term performance.
