This ICON Vehicle Dynamics 2.5-3” coilover system is a great way to lift your 4WD 2023 Ford F-250/F-350 Super Duty while drastically improving ride quality and performance. The Stage 3 system is perfect for on-road and off-road use including towing, job site duty and general off-road adventure. The advantage of utilizing a coilover conversion kit is that they have been designed to increase the overall damping ability of the vehicle while at the same time allowing for user-defined ride height adjustment. The 2.5" Remote Reservoir Coilover featured in these kits is based off of ICON’s 2.5 VS Series shock line - meaning that features like ICON engineered coil springs, FK Rod End bearings, and vehicle-specific valving come standard. ICON's Stage 3 System is comprised of ICON 2.5 Series remote reservoir coilovers with adjustable ride height, fabricated Radius arms, 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 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.
