About this kit
4.5-Inch Coilover Conversion, fitment-checked
A coilover conversion rather than a coil-and-shock kit. Vertex 2.5 adjustable coilovers go in at the front, left and right, with V2 monotube shocks kept at the rear.
This is where the 4.5-inch Super Duty range changes character: instead of a front coil with a separate damper, it converts the front to Vertex 2.5 adjustable coilovers, supplied as matched left and right units. The rear stays on V2 monotube shocks with a 4.5-inch block and U-bolt set. A companion part number takes the conversion further by putting Vertex units at the rear as well, so check both ends before ordering. Shipping weight: 165 lb.
