Built to meet and exceed all expectations and withstand anything you can throw at them. 3/16 steel construction, 1/4 mounting brackets and high stress areas. These do require some very minor trimming to allow the longer brackets to run up the frame rails. Allow 4 additional 1/2 inch mounting bolts per side for added strength. Comes standard with D-Ring clevis mounts. This is a WELD UP KIT will need fabricated upon receiving. Requires a large flat welding table, welder, grinders, and other basic fabrication tools.
