Barnes 4wd Jeep Skid Plates are made to protect the belly of your Jeep and give you a smooth surface to slide on. Each Skid plate has a 1.5" lip on the front and back of the skid to add rigidity and prevent the skid plate from digging into obstacles. These skids do not have drilled holes for the transfer case so you are free to use any transmission and transfer case that you wish. Our skid plates are Laser cut from 1/4" A50 Steel Plate and made in the USA.  This is for a 1976-1986 CJ.
