Stryker F450 RAD Identity Series Lift Kit for Diesel Brothers Truck Giveaway
Stryker F450 RAD Identity Series Lift Kit for Diesel Brothers Truck Giveaway

We are happy to release our newest generation of suspension lifts! Our “RAD” series (Radius Arm Drop) series. This new RAD line is the perfect balance between those that need an extremely rugged suspension lift, yet still want it to be stylish!

We address everything in this kit. Our coils are designed to mimic the factory specs and provide a great ride. Our rear blocks have the bumpstop pads built in to utilize the factory rear bumpstops that Ford designed in for the heavy hauling these trucks were designed for. Our drop brackets for the radius are the beefiest in the industry!

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.
