About this kit
4.5-Inch Vertex Coilover Conversion Kit, fitment-checked
Rough Country 50011 is a 4.5-inch coilover conversion upgrade built around a pair of Vertex 2.5 adjustable front coilovers (left and right) packed with the Ford Super Duty (17-22) kit box. It swaps the front corners over to ride-height-adjustable coilovers with added damping, and adds secondary V2 monotube shocks for a second stage of front control. It fits only trucks already running a 4.5-inch Rough Country lift kit, and installation calls for cutting and drilling.
