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 6 system is perfect for on-road and off-road use including towing, job site duty and general off-road adventure. ICON's Stage 6 System is comprised of dual rate coil springs optimized for trucks equipped with gasoline engines, dual steering stabilizer kit with ICON 2.0 Aluminum Series stabilizers, on-vehicle adjustable front track bar, fabricated radius arms, and ICON 2.5 Aluminum Series CDEV remote reservoir front and CDEV piggyback reservoir rear shocks. Focus on driving and let ICON Intelligent Control (IIC) read the terrain and make near-instant adjustments via the Compression Damping Electronic Valve (CDEV) at each individual shock. Control the system wirelessly through the IIC app on your phone and once configured the system functions without driver input. This stage sees the inclusion of the ICON Vehicle Dynamics Ford Super Duty 4-Link kit further improving performance by eliminating suspension bind commonly experienced with factory radius arms during articulation and allows on-vehicle caster angle adjustment. This “freeing up” of the front end and the ability of the 4-Link Kit to maintain positive caster through the range of travel equates to an unparalleled ride quality in all conditions. 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.
