Transform The Way Your Super Duty Rides

If you want a lift that does more than just add height, the ICON 4.5" Dual Rate Coil Spring Kit is the kind of upgrade that changes how your truck feels on every drive. The dual rate design gives you a smooth, controlled ride on the road while still delivering the support and resistance you need once the suspension really starts to work. That means you get comfort on your daily commute and confidence when you hit rough trails or tow heavy loads. These springs also open the door to fitting up to 37-inch tires, giving your Super Duty a more commanding presence without sacrificing drivability. With a semi-gloss powder coat finish, they’re built to withstand the elements and keep looking sharp long after installation. Knowing they carry a lifetime warranty against sagging or breakage adds another layer of confidence in your investment. This is a kit that balances performance, durability, and everyday usability in a way few suspension upgrades can.

Designed For Diesel Power And Larger Tires

The ICON 64012 Coil Spring Kit is engineered specifically for 2023-2025 Ford F250 and F350 Super Duty 4WD diesel models. Delivering 4.5 inches of front lift, the springs are tuned with vehicle-specific rates that account for the added weight of the diesel engine. The dual rate design uses a softer initial spring rate to provide a comfortable ride on the street, while the firmer secondary rate engages as the suspension compresses to control bottoming and improve off-road capability. When paired with ICON shocks, these coils allow for increased wheel travel and more consistent performance across demanding conditions. The kit is 100 percent bolt-on, making installation straightforward with no major modifications required. A durable semi-gloss powder coat protects the springs from corrosion, while ICON backs them with a lifetime warranty for sagging or breakage. It is important to note that these springs are not compatible with F-450 or F-550 models, and trucks equipped with the Tremor package will see a 3.5 inch lift instead of the full 4.5 inches. For drivers looking to run 37-inch tires while maintaining proper ride dynamics, this coil spring kit provides a well-rounded and dependable solution.
