This ICON Vehicle Dynamics 2.5” suspension system is a great way to lift your 4WD 2023-2026 Ford F-250/F-350 Super Duty while drastically improving ride quality and performance. The Stage 4 system is perfect for on-road and off-road use including towing, job site duty and general off-road adventure. Also included in this stage is ICON's CDC Valve front and rear shocks, for those desiring an easy way to tune the ride externally with 10 settings, from soft to hard. ICON's Stage 4 System is comprised of dual rate coil springs optimized for trucks equipped with diesel engines, fabricated radius arms, on-vehicle adjustable front track bar, rear leaf spring expansion packs with blocks and U-bolts for a more compliant ride and reduced axle wrap, and ICON 2.5 Aluminum Series CDCV remote reservoir front and CDCV piggyback reservoir rear shocks. This stage sees the inclusion of the ICON Vehicle Dynamics Ford Super Duty Radius Arm System that feature a sealed pivot bushing that minimizes road feedback and ensures a long life and quiet operation. Additionally, their fabricated, fully boxed design ensures strength and utilizes a profile optimized for tire clearance at full steering lock, making a 37” tall tire clear without coming in contact with the radius arm. With the endless hours ICON has spent testing and tuning our suspension components and shocks as a complete package, you can rest assured you have the best suspension solution on the market.
