About this kit
3-Inch Vertex Coilover Conversion Kit, fitment-checked
Rough Country 50015 converts the front suspension of a 3-inch-lifted Ford F-250 or F-350 Super Duty 4WD to adjustable coilovers. The kit pairs left- and right-hand Vertex 2.5 adjustable front units with a kit box of fabricated coilover mounts and reservoir bracketry, so ride height can be dialed in. It fits only trucks already running a 3-inch Rough Country lift kit, and it does not fit diesel models.
This 3-inch coilover conversion kit for the 2005–2022 Ford F-250 and F-350 Super Duty 4WD replaces the factory front damping setup with adjustable Vertex 2.5 coilovers, one per side, plus a secondary front monotube shock for added damping control. Supported trims run from XL and XLT through Lariat, King Ranch, Platinum, and Limited as listed in the fitment section. Two conditions decide whether this kit is right for your truck: a 3-inch Rough Country lift kit must already be installed, and diesel models are excluded. Installation calls for cutting and drilling; a downloadable Rough Country installation guide is available.
