The 4" Super Duty Radius Arm Systems include everything you need and more, including bullet proof radius arms made with 1" steel for optimal ground clearance compared to other drop bracket kits on the market, and gas or diesel specific coils that are made in America that will not sag. A 1-1/2" steel track bar is included in the 4" system to properly align the front axle after lifting. To avoid stacking rear blocks or going too tall with a single block, Zone includes a 5" cast iron block with an integrated bump stop.
