Build Your Super Duty With Strength And Comfort

If you’re lifting your truck and want real performance without sacrificing drivability, the ICON Stage 3 Suspension System with Radius Arms is exactly what your 2023–2025 Super Duty needs. This setup does more than give you a bold new stance, it transforms how your truck rides, steers, and handles in the real world. From daily highway miles to job site runs and weekend trail use, it’s designed to feel stable, planted, and smooth. The 4.5 inches of front lift pairs perfectly with ICON’s 2.5 internal reservoir shocks, giving you the control you need over rough roads or when towing heavy gear. The dual steering stabilizers help keep larger tires in check and eliminate that vague, wandering feel through the wheel. You’ll also get fabricated radius arms that add serious strength and allow for proper alignment without needing drop brackets. If your truck works hard, drives far, and goes where others won't, this kit delivers the confidence to back it all up.

Suspension Geometry Tuned For Bigger Tires And Bigger Loads

ICON’s Stage 3 Suspension System with Radius Arms is engineered to deliver improved suspension performance and durability across a wide range of use cases. At the core are dual rate coil springs that deliver a smooth initial ride and a firmer response deeper in the travel, ideal for on-road comfort and off-road stability. ICON’s 2.5 Aluminum Series shocks are tuned for gas-powered Super Duty models and provide better heat management, damping control, and fade resistance than smaller 2.0 shocks. The fabricated radius arms feature built-in caster cams for on-vehicle adjustments, increased tire clearance at full steering lock, and greater structural strength than stock arms. This design eliminates the need for radius arm drop brackets, helping maintain ground clearance under the chassis. A heavy-duty track bar drop bracket is included to center the axle and reduce bump steer, improving steering feel both on and off the road. Stainless steel brake lines, sway bar drop brackets, and bump stop spacers round out the system, ensuring every component works together seamlessly.
