4 1/2" F250 F350 Lift Kits released in our newest generation of suspension lifts! Our “RAD” series (Radius Arm Drop) series. This new 4 1/2" F250 F350 RAD Series line is the perfect balance between those that need an extremely rugged suspension lift, yet still want it to be stylish! 

We went about it a little different. Instead of the drop bracket going up inside the factory radius arm pocket, we designed ours to mount uniquely outside. That adds width and strength. These features cost more to produce, but the end result is unmatched. All our steel is U.S. made and is at least ¼”, and in some instances even larger.
