Tame Rough Roads And Tow With Total Confidence

If your Super Duty feels overwhelmed by rough terrain, big loads, or oversized tires, the ICON Stage 9 Coilover Conversion System with Radius Arms will change the way you think about your truck’s capability. Designed specifically for 2023-2025 Ford F-250 and F-350 4WD models, this system gives you 4-5.5 inches of front lift and everything you need to support larger wheels and tires without losing comfort or control. Whether you're daily driving, towing heavy gear, or heading down unpaved roads, the ride stays smooth and predictable. Dual front shocks handle rough impacts with ease while the rear 2.5 piggyback shocks keep things stable when the bed is loaded or the trail gets bumpy. ICON’s Intelligent Control system makes real-time damping adjustments automatically, so the suspension does the thinking for you while you focus on the drive. Radius arms add more strength up front and improve clearance at full lock, giving your steering more freedom and better alignment options. It’s a complete solution for truck owners who want their suspension to work as hard as they do.

Radius Arm System With Dual Front Shock Control

The Stage 9 kit with radius arms is a purpose-built performance suspension system engineered to deliver control, stability, and adaptability across a wide range of driving conditions. At the front of the system are ICON’s 2.5 Series CDEV coilovers paired with secondary 2.5 CDCV remote reservoir shocks, providing increased damping capability and fade resistance during aggressive use. These shocks are managed by ICON’s IIC system, which uses sensors to monitor terrain and dynamically adjust compression settings at each corner without needing manual input. Radius arms come standard and include built-in caster cams, helping maintain proper geometry throughout the suspension's travel while eliminating the need for bulky drop brackets. A fabricated track bar drop bracket corrects geometry and reduces bump steer, while the adjustable track bar allows for fine-tuned axle alignment. In the rear, 5-inch heavy-duty fabricated lift blocks are paired with ICON’s piggyback reservoir shocks, specifically valved to enhance both towing performance and off-road comfort. Additional upgrades like stainless brake lines, sway bar drop brackets, and bump stop spacers ensure the entire system works together as a high-performance suspension package.
