Take On The Road Ahead With Confidence

When it comes to lifting your Super Duty, you want more than just height, you want comfort, performance, and real-world functionality. The ICON Stage 1 Suspension System with Radius Arms is built for drivers who split their time between job sites, back roads, and towing duties. With 2.5 inches of lift, your truck gets the stance you’re after while keeping ride quality smooth and predictable on all terrain. ICON’s fabricated radius arms not only add serious strength but also improve tire clearance so you can fit up to 37-inch tires without rubbing. Whether you're hauling equipment or heading into the hills for a weekend getaway, the tuned dual rate coils and 2.0 Aluminum Series shocks give your truck a confident feel without compromising on control. Every part of this system is designed to bolt on without cutting or welding, making the install straightforward for most garages. Backed by ICON’s proven testing and engineering, this kit delivers a ride that’s as capable as it looks.

Every Piece Works Together For Maximum Performance

This Stage 1 system combines ICON’s dual rate coil springs and 2.0 Aluminum Series internal reservoir shocks to deliver improved wheel travel, better control, and a more planted feel compared to stock. The coil springs are tuned specifically for diesel trucks, offering the perfect balance between load handling and ride comfort. ICON’s fabricated radius arms feature on-vehicle caster adjustment and a sealed pivot bushing that reduces feedback while keeping operation quiet. The internal reservoir shocks are valved for this specific truck platform and are fully rebuildable and re-tunable for future upgrades. Even under heavy loads or rough roads, the geometry of the suspension remains stable and predictable thanks to the added rigidity from the radius arm design. The system maintains full towing capacity and requires no modifications to the driveshaft. With a fully bolt-on installation, this is a performance upgrade that delivers real improvements without added complexity.
