The Dirt King frame horns are a great start for those looking to build their own custom bolt on bumper. They’re laser cut and have two holes on the side to locate the frame horns to factory mounts. The front crossmember will need to be cut off which allows the bumper to have a tighter fit. This doesn’t compromise strength once the bumper is finished. The frame horns are designed to fit 1.75″ tubing and will accept 2″ with some modifications.
