Give Your Super Duty The Lift It Deserves

If you’re ready to transform the stance and ride of your gas-powered Super Duty, the ICON 4.5" Stage 1 Suspension System with Expansion Packs is a solid place to start. This kit delivers a noticeable lift without going overboard, giving your 2023-2025 F-250 or F-350 the clearance and control to handle bigger tires and tougher terrain. It's designed to improve comfort during everyday driving while also making your truck feel more confident under load or while towing. The ride is smooth but firm, and thanks to the rear leaf expansion packs, you get better ride quality than you'd find with standard lift blocks. This setup works great for job site rigs, weekend towing, or trucks that live on gravel and backroads. The dual rate coil springs help soak up rough patches while maintaining stability on the highway. It’s the kind of upgrade you’ll feel immediately, whether you're pulling onto a job site or cruising to your next campsite.

Tuned Suspension Built For Real World Performance

ICON designed this Stage 1 system with a full vehicle-specific approach to improve suspension dynamics without compromising daily drivability. The 4.5" front lift is achieved with precision-tuned dual rate coil springs made specifically for 4WD gas trucks, allowing for a smooth initial response and a firmer secondary rate when the suspension compresses. The included 2.0 Aluminum Series shocks are internally valved for the Super Duty’s weight and deliver improved control during both light off-road driving and highway use. Expansion packs in the rear replace basic lift blocks, offering better axle wrap control and more refined bump compliance. Radius arm drop brackets correct caster for proper alignment specs, while the track bar drop bracket helps improve steering geometry and reduce bump steer. Upgraded stainless steel front brake lines are included to maintain safe braking under extended suspension travel. Every part of this system is bolt-on and backed by ICON’s lifetime guarantee on springs and fabricated components, making it a smart, long-term suspension investment.
