Instead of installing a spacer leveling kit that doesn't improve your suspension handling, install something that actually improves the ride in your 2005-2024 Ford Powerstroke. These springs provide rugged load handling capabilities while maintaining an extremely comfortable ride. Designed to add 2.5" of lift, these dual springs utilize a softer initial spring rate over factory for improved on-road comfort, while also using a higher secondary spring rate to provide stability and performance in harsh terrains. Manufactured from high tensile steel and engineered with properly sized wire diameter. This results in maximum reliability without premature coil bind.
