The frame reinforcement plate is laser-cut 1/4″ steel. It has the holes for both the stock power steering box and the f-150 4×4 power steering box. The plate is designed to be welded to the outside of the frame. We include the 1/4″ wall tubes to replace the thin, stock frame braces inside the frame that collapse and in turn allow the frame to collapse. To install the tubes, you will need to grind them to fit your frame. The kit includes the frame plate, three 1/4″ wall tubes, three grade 8 bolts, and three nyloc nuts. This is a BC Broncos Original part.
