Turn Your Gas Super Duty Into A Confident Performer

If you own a 2023-2025 Ford Super Duty gas truck and want a suspension that truly changes how it feels behind the wheel, the ICON 2.5" Stage 4 System with Radius Arms is built for you. This kit gives your truck the clearance it needs while making the ride more controlled and comfortable whether you’re on the highway, pulling a trailer, or venturing off-road. The magic comes from ICON’s CDC Valve shocks that let you adjust compression with ten different settings, so you can fine-tune the ride to match the task at hand. Dual-rate coil springs are tuned specifically for gas engines, giving you balance and stability without a harsh ride. The fabricated radius arms not only strengthen your front end but also improve steering feel and allow you to run up to 37-inch tires without rubbing. An adjustable track bar keeps your axle perfectly centered, which makes a big difference in handling. With everything bolting on cleanly and no need for cutting, this system upgrades your truck without adding complications.

Advanced Suspension Technology Designed For Gas Applications

The Stage 4 ICON system is engineered as a complete performance package for 2023-2025 F-250 and F-350 Super Duty gas models. At its core are dual-rate coil springs that provide 2.5 inches of lift while being specifically tuned for the characteristics of gasoline engines. The included 2.5 Aluminum Series shocks feature remote reservoirs in the front and piggyback reservoirs in the rear, each equipped with CDC Valves that allow ten levels of compression adjustment. This lets you quickly adapt damping to road conditions or payload without removing any components. The fabricated, fully boxed radius arms use sealed pivot bushings that reduce road noise while improving caster correction and long-term durability. An adjustable front track bar ensures the axle remains properly aligned under all conditions, an important factor when running larger tires. Compared to stock, this suspension setup delivers increased wheel travel, reduced body roll, and consistent control while maintaining full towing and hauling capabilities. With its bolt-on design and rebuildable shocks, this system provides a long-term upgrade that balances strength, adjustability, and ride quality.
