ICON Vehicle Dynamics 64011 4.5" Dual Rate Coil Spring Kit for the Ford F250 / F350 aims to optimize the truck's suspension system for various driving conditions. The dual rate design offers a combination of a softer initial rate for smooth rides on rough terrain and a stiffer secondary rate for improved stability during heavy loads or aggressive driving. By replacing the stock springs with Icon's dual rate springs, this kit enhances the truck's overall suspension performance. It helps reduce body roll, improve cornering capabilities, and enhance the vehicle's off-road capabilities. Additionally, the kit provides increased ground clearance, allowing for larger tire fitment and more adventurous off-road excursions.
