Turn Your Super Duty Into A True Performer

If you’re looking to transform your Super Duty’s stance and ride without sacrificing work capability, the ICON 2.5" Stage 1 Suspension System with Radius Arms and Expansion Packs is the upgrade you’ve been waiting for. This system is designed for truck owners who need real-world performance both on the highway and off the beaten path. The 2.5-inch lift gives your truck a confident, leveled stance while making room for up to 37-inch tires, so you can take on trails, job sites, or long hauls with ease. The ICON dual rate coil springs and 2.0 Aluminum Series shocks smooth out bumps and uneven terrain while still keeping towing stability intact. You’ll also notice a more connected feel through corners and over rough ground thanks to the upgraded radius arms that reduce deflection and improve tire clearance. What makes this setup stand out is how natural it feels behind the wheel, refined when you want comfort and firm when you need control. It’s a perfect balance between capability and comfort, giving your truck that premium feel every time you drive it.

Built With Strength And Tuned For Precision Handling

The ICON Stage 1 system is built to do more than lift your truck, it’s engineered to enhance its entire suspension geometry. Dual rate coil springs are specifically tuned for diesel-powered Super Duty models, providing consistent performance whether your bed is loaded or empty. The 2.0 Aluminum Series internal reservoir shocks are designed with vehicle-specific valving, offering a noticeable improvement in ride quality and damping control across all terrains. ICON’s fully boxed radius arms are fabricated for maximum durability and feature on-vehicle caster adjustment for precise alignment and handling. In the rear, the leaf spring expansion packs and blocks work together to reduce axle wrap and smooth out the ride under heavy loads. Every component is designed to bolt directly into place, requiring no cutting or welding for installation. The result is a system that not only lifts your truck but elevates its capability and comfort far beyond stock performance.
