Take On Any Road With Confidence

If you want your Super Duty to perform at its best no matter where you drive, the ICON Stage 8 4.5" Lift System with Radius Arms is built for the job. This kit gives your truck the clearance for bigger, more aggressive tires while also transforming ride quality on pavement, gravel, and trails. The dual rate coil springs are designed to balance comfort and control, keeping things smooth on the highway while firming up when the terrain gets rough. ICON’s 2.5 Series shocks with remote reservoirs work hard to resist overheating, so you can keep pushing through long off-road runs without losing performance. The included radius arms are stronger than factory and engineered to improve tire clearance and ground clearance for real-world benefits you will notice. To top it off, the ICON Intelligent Control system automatically adjusts damping to match changing conditions, so you can focus on driving instead of fine-tuning. Whether you use your truck for work, towing, or adventure, this suspension gives you the confidence to handle it all.

Engineered Performance That Works Everywhere

The Stage 8 system is loaded with premium components that work together as a complete suspension solution. ICON’s 2.5 Aluminum Series CDEV shocks are tuned specifically for the F-250 and F-350, delivering excellent control while resisting fade thanks to increased oil volume and heat dissipation. The Intelligent Control module reads terrain and chassis movement, making near-instant damping changes through each shock’s electronic valve. The fabricated radius arms feature built-in caster cams for on-vehicle adjustment, providing better alignment and improved steering geometry compared to stock. An adjustable track bar pairs with a drop bracket to re-center the axle and eliminate bump steer, which results in tighter and more predictable handling. ICON also includes a 2.5 Centerline steering stabilizer with a piggyback reservoir to reduce steering feedback from larger tires while maintaining ground clearance. Stainless steel braided brake lines, heavy-duty rear lift blocks, and rebuildable shocks round out the package, making this kit as durable as it is capable. With ICON’s testing and engineering, you can count on this system to perform whether you are hauling, towing, or exploring rough trails.
