ICON 23 Ford F250/350 Front 2.5in. Diesel Dual Rate Spring Kit

This kit includes a pair of ICON 2.5-inch front dual-rate coil springs and caster correction cams for your 2023 Ford F-250 or F-350 Super Duty. These springs are specifically tuned for trucks equipped with diesel engines, aiming to give you a better ride both on the pavement and when you head off-road.

The dual-rate design is a key feature here. It means the spring acts differently depending on how much it's compressed. Initially, it's set up for a more comfortable ride on the street, soaking up bumps more easily than stock. As you compress the spring further, like when hitting a bump off-road or during hard braking, a second, firmer rate engages. This helps prevent the suspension from bottoming out and gives you more control when you need it most. The springs are finished with a dual-stage, semi-gloss powder coat to help them resist corrosion. Because these are taller than stock, the kit also comes with caster correction cams to help get your alignment angles back in spec.

This is a 100% bolt-on system, making installation straightforward. ICON backs these springs with a lifetime warranty against sagging or breakage, so you can install them with confidence.
