Experience A Suspension Upgrade That Changes Everything

If you own a 2023-2025 Ford Super Duty gas truck and want to transform how it feels on and off the road, the ICON 2.5" Stage 5 Suspension System with Radius Arms and Expansion Pack is the way to go. This kit isn’t just about gaining a little extra clearance, it’s about improving comfort, control, and confidence in every driving situation. With ICON’s CDC Valve shocks, you can fine-tune the ride with ten different compression settings, whether you’re cruising on the highway, towing heavy gear, or working your way through rough terrain. The rear expansion packs make the truck feel more compliant while reducing axle wrap, so you’ll notice smoother performance under acceleration or when hauling weight. Dual steering stabilizers keep the wheel steady even with oversized tires, making long drives less fatiguing and off-road trails easier to handle. Add in fabricated radius arms for strength and proper caster along with clearance for up to 37-inch tires, and this system proves itself as a complete upgrade. With straightforward bolt-on installation, you’ll be back on the road or trail with a suspension that feels brand new.

Complete Suspension Engineering Designed For Gas Applications

The Stage 5 Expansion Pack system from ICON is built with precision to meet the demands of 2023-2025 F-250 and F-350 Super Duty gas trucks. At the front, dual-rate coil springs provide 2.5 inches of lift while being tuned specifically for gasoline engines, ensuring the right balance between comfort and support. The ICON 2.5 Aluminum Series shocks feature remote reservoirs in the front and piggyback reservoirs in the rear, each equipped with CDC Valves for ten levels of external compression adjustment. This allows drivers to adapt suspension performance to towing, hauling, or off-road conditions with ease. Fully boxed fabricated radius arms are included, providing increased strength, caster correction, and clearance to fit 37-inch tires at full steering lock. The system also incorporates rear leaf spring expansion packs with blocks and U-bolts, reducing axle wrap and improving compliance over rough terrain. An adjustable front track bar keeps the axle centered for proper handling and alignment, especially when running larger tires. With shocks that are fully rebuildable and components backed by ICON’s lifetime guarantees, this system delivers long-term durability alongside a significant improvement in ride quality and performance.
