About this kit
4.5-Inch Vertex Coilover Kit, fitment-checked
Vertex at both ends. The front takes matched left and right Vertex 2.5 adjustable coilovers and the rear takes a pair of Vertex 2.5 units as well, making this the fully adjustable build at 4.5 inches.
Where the other coilover conversion for this truck keeps monotube shocks at the rear, this one carries Vertex 2.5 units front and rear — matched left and right at the front, a pair at the back — so damping is adjustable at both ends. The rear block and U-bolt set is the 4.5-inch version. That difference is invisible on the fitment table, which is identical across the whole Super Duty coil range, so the part number is the specification. Shipping weight: 165 lb.
