Built For Trucks That Work And Play Hard

If you're looking for a suspension upgrade that delivers both serious off-road capability and smooth on-road comfort, the ICON Stage 3 4.5" Lift System with Radius Arms and Expansion Packs hits the sweet spot. Designed for 2023-2025 Ford F-250 and F-350 diesel trucks, this system gives your Super Duty a bold stance, better ride quality, and more control when it matters most. The front end benefits from dual rate coil springs that keep things smooth on the road and firm up when the trail gets rough. In the back, the leaf spring expansion packs provide 2 inches of lift while improving rear-end compliance, helping your truck stay planted over bumps and under load. Whether you're towing heavy gear, cruising highways, or exploring gravel roads, the 2.5 Series shocks with internal reservoirs soak up the abuse and keep your ride stable. The heavy-duty radius arms not only improve strength and clearance, but also let you fine-tune caster on the truck itself. It’s a well-rounded kit that gives your Super Duty the lift it needs without giving up the comfort you want.

Tuned Suspension With Real World Strength And Precision

The ICON Stage 3 4.5" Suspension System with Radius Arms and Expansion Packs is engineered for truck owners who demand both performance and durability. At the front, ICON’s dual rate coil springs provide a full 4.5 inches of lift while improving ride quality across changing terrain. The included 2.5 Aluminum Series internal reservoir shocks are tuned specifically for Super Duty applications and feature hard anodized bodies and 7/8-inch shafts for improved cooling and long-term durability. ICON’s fabricated radius arms offer increased strength over stock, while built-in caster cams allow for on-vehicle adjustment to dial in alignment and handling. The rear leaf spring expansion packs replace traditional lift blocks to provide 2 inches of rear lift with better ride quality, reduced axle wrap, and improved traction when towing or off-roading. The system also includes a track bar drop bracket for proper axle alignment and dual opposing steering stabilizers to reduce feedback and improve control with oversized tires. Stainless braided brake lines, sway bar drop brackets, and bump stop spacers complete the package, making this a comprehensive solution built to handle real-world abuse with confidence.
