Upgrade Your Suspension Without Compromising Ride Quality

If you're ready to lift your Super Duty and want real performance gains without the usual ride penalties, the ICON Stage 4 Suspension System with Expansion Packs is an easy yes. Built for 2023–2025 F-250 and F-350 gas models, this system gives you a true 4.5 inches of front lift and 2 inches in the rear with a setup that’s built to work just as hard as your truck does. Whether you're towing, exploring rough terrain, or just driving to work, it keeps the ride comfortable and responsive. ICON's expansion packs out back give you smoother small-bump absorption and reduce axle wrap compared to basic lift blocks, making a big difference in daily drivability. The 2.5 remote reservoir shocks feel composed on the road and stay cool under extended off-road use or while hauling heavier loads. With dual steering stabilizers and an adjustable track bar included, you’ll notice a more confident steering feel, even with larger tires. This is a full-system upgrade that improves control, comfort, and capability all in one package.

Suspension Engineering Designed For Real Truck Use

The Stage 4 system with expansion packs is engineered by ICON to provide serious performance gains for gas-powered Super Duty owners who want more than just a visual lift. The dual rate coil springs up front are tuned specifically for the weight and geometry of the 2023–2025 F-250 and F-350 platform, offering a softer ride over uneven roads and firmer control under compression. The 2.5 Aluminum Series shocks include remote reservoirs to improve oil capacity and reduce shock fade during long drives or off-road heat buildup. In the rear, ICON’s expansion packs replace traditional lift blocks, offering better traction, axle control, and compliance over bumpy terrain. Radius arm drop brackets are included to restore caster for proper alignment, while the adjustable track bar fine-tunes axle position and reduces bump steer. Dual 2.0 steering stabilizers work together to reduce steering feedback, especially when running oversized tires. With stainless brake lines, sway bar brackets, and bump stop spacers included, this is a complete bolt-on solution built for real-world truck applications.
