Take Your Gas Super Duty To New Heights

When you are ready to give your truck the lift and ride quality it deserves, the ICON 4.5" Dual Rate Coil Spring Kit is a serious upgrade. These springs not only add height for a more commanding stance but also transform how your truck feels on the road and trail. The dual rate design starts with a softer initial spring rate that smooths out everyday driving, then transitions into a firmer rate as the suspension compresses to handle bumps, dips, and off-road terrain with confidence. That balance makes a world of difference whether you are cruising down the highway or powering through rough backroads. With clearance for tires up to 37 inches, your truck can take on a bolder look and improved capability without sacrificing drivability. The semi-gloss powder coat keeps the springs looking sharp while protecting them from the elements. To top it off, ICON backs these coils with a lifetime warranty, so you know they are built to last as long as your truck does.

Engineered To Match The Demands Of Gas Engines

The ICON 64013 Coil Spring Kit is built specifically for 2023-2025 Ford F250 and F350 Super Duty 4WD trucks equipped with gasoline engines. Delivering 4.5 inches of lift over stock, these dual rate springs provide the perfect balance of on-road comfort and off-road control. The initial spring rate is tuned for a smooth ride during daily use, while the firmer secondary rate engages under compression to prevent bottoming and improve suspension performance on rough terrain. When paired with ICON shocks, these coils also increase wheel travel, making them a great choice for drivers who want both lift and capability. Installation is a straightforward bolt-on process, requiring no major modifications, and the springs are finished with a corrosion resistant semi-gloss powder coat. ICON includes a lifetime warranty against sagging or breakage, ensuring confidence in long-term reliability. For trucks with the Tremor package, the lift height will measure 3.5 inches instead of the full 4.5 inches. These springs are not compatible with F-450 or F-550 models, making them purpose-built for F250 and F350 gas-powered trucks.
