Get The Lift You Want Without Compromising Ride Quality

If you're lifting your Super Duty and want real performance that matches your truck's potential, the ICON Stage 4 Coilover Conversion System with Radius Arms is a smart move. Built for 2023-2025 Ford F-250 and F-350 4WD trucks, this kit gives you 4-5.5 inches of front lift and serious upgrades where it matters most, ride quality, control, and off-road capability. The 2.5 Series coilovers and piggyback rear shocks soak up bumps, ruts, and uneven pavement without making your truck feel harsh or floaty. ICON’s fabricated radius arms not only add strength but also help correct suspension angles while improving tire clearance and overall ground clearance. On-road, the dual steering stabilizers and adjustable track bar keep steering feel tight and responsive, especially if you’ve added bigger wheels and tires. Whether you're towing, working, or heading out for a weekend on the trail, this kit helps your truck handle the job without giving up comfort or control. It's more than a lift, it’s a full-system upgrade for serious truck owners.

Radius Arm Geometry And Reservoir Control In One Package

The ICON K63214R Stage 4 system offers a complete suspension solution engineered to maximize performance, geometry, and durability across varied driving conditions. Front lift is handled by ICON’s 2.5 Series remote reservoir coilovers, which mount directly into the factory buckets and offer adjustable ride height from 4 to 5.5 inches. The rear features 2.5 Series piggyback reservoir shocks, delivering improved heat dissipation, vehicle-specific damping, and consistent control under load. Replacing the factory arms, ICON’s fabricated radius arms offer maintenance-free bushings, integrated caster cams, and improved clearance at full steering lock, eliminating the need for drop brackets. A fabricated track bar bracket and fully adjustable track bar allow proper axle centering and minimize bump steer, both critical for maintaining predictable steering with added lift. Dual 2.0 steering stabilizers further reduce unwanted feedback, giving you more confidence at higher speeds or with oversized tires. This system also includes stainless steel braided brake lines, sway bar drop brackets, and bump stop spacers, completing a high-performance package built to handle real-world duty.
