This ICON Vehicle Dynamics 2.5” suspension system is a great way to lift your 4WD 2023-2025 Ford F-250/F-350 Super Duty while drastically improving ride quality and performance. The Stage 1 system is perfect for on-road and light duty off-road use including towing, job site duty and general off-road adventure. ICON's Stage 1 System is comprised of dual rate coil springs optimized for trucks equipped with diesel engines, fabricated radius arms, and ICON 2.0 Aluminum Series front and rear internal reservoir 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.
