Give Your Super Duty The Ride It Deserves

If your 2023-2025 Super Duty diesel is ready for a lift, but you’re not willing to settle for a rough ride, this ICON 2.5" Stage 4 Suspension System with Expansion Pack delivers the best of both worlds. It's built for serious truck owners who need better handling on and off the road, whether you're hauling, towing, or heading into the backcountry. The ride quality is noticeably smoother thanks to ICON’s dual-rate coil springs and the added leaf spring expansion packs that help reduce axle wrap under load. The included CDC Valve shocks let you fine-tune your suspension with 10 different compression settings, so whether you're running empty or loaded down, you can always dial it in. What really stands out is the control this system brings to the table, especially when pushing the truck through uneven terrain or tight turns. The fully boxed radius arms are designed for strength and clearance, giving you room to run 37-inch tires without rubbing. It's a total suspension upgrade that doesn’t just lift your truck, it refines how it drives every single day.

Built For Diesel Performance With Tuned Suspension Precision

This Stage 4 ICON system is engineered with every detail tailored specifically to the 2023-2025 Ford F-250 and F-350 Super Duty diesel platforms. It includes 2.5" front lift coil springs with dual-rate tuning to balance ride comfort and support for the heavier diesel powertrain. 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 external compression adjustments. This allows for rapid tuning based on load, road conditions, or off-road demands without needing to remove any components. The included rear leaf spring expansion packs work alongside lift blocks and U-bolts to ease ride stiffness and reduce axle wrap, a common issue under heavy acceleration or towing. Heavy-duty radius arms feature sealed pivot bushings to reduce road noise while improving caster correction and structural integrity. An adjustable front track bar keeps the front axle properly centered, especially important when running larger tires. This is a complete, bolt-on solution that requires no cutting or driveshaft modifications, making it as installation-friendly as it is capable.
