Upgrade Your Gas Super Duty Without Compromise

If you want your 2023-2025 Ford Super Duty gas truck to handle better in every situation, the ICON 2.5" Stage 4 Suspension System with Radius Arms and Expansion Pack is a game changer. This kit doesn’t just lift your truck for extra clearance, it transforms the way it feels on the road and out in the dirt. ICON’s CDC Valve shocks give you ten compression settings so you can soften the ride for daily driving or firm it up when towing or tackling trails. The rear expansion packs calm down axle wrap and make the ride more compliant, which is especially noticeable when carrying weight or climbing hills. Fabricated radius arms not only boost strength but also improve steering feel while creating the clearance needed to run 37-inch tires with confidence. Add in dual-rate coil springs designed specifically for gas applications, and you get the right balance of comfort and control. With a simple bolt-on installation and no cutting required, this system gives your truck a suspension upgrade that’s built for real-world use.

Advanced Suspension Technology Tuned For Gas Applications

The Stage 4 Expansion Pack system from ICON is engineered as a complete upgrade for 2023-2025 F-250 and F-350 Super Duty gas models. At the front, dual-rate coil springs deliver 2.5 inches of lift while being tuned to match the weight and characteristics of gasoline engines. The 2.5 Aluminum Series shocks include remote reservoirs in the front and piggyback reservoirs in the rear, with CDC Valves that allow for ten levels of external compression adjustment. This lets you quickly tailor the ride to different road conditions, loads, or off-road terrain. The fully boxed fabricated radius arms feature sealed pivot bushings that reduce road feedback and increase long-term durability while also improving caster correction. Rear leaf spring expansion packs are included with blocks and U-bolts, which reduce axle wrap and create a smoother ride when the suspension is under strain. With an adjustable track bar to keep the front axle aligned and increased wheel travel compared to stock, this system delivers measurable performance gains while maintaining towing and hauling capacity. Built with rebuildable shocks and backed by ICON’s lifetime spring and component guarantee, it’s a suspension solution designed for both strength and longevity.
