Most XJs left the factory with no belly, rocker, or gas tank skidplates. One good wheeling trip and its likely you will be killing vital components. While the XJ was available from the factory with an “Up Country” or “Off Road” package that included skidplates, they are only 1⁄8-inch-thick. And, if you’ve got a late model XJ, good luck finding the gas tank skid. One of the first parts we put on this XJ was the T&T Customs belly skid. Also note the GenRight Off Road gas tank (with skidplate). Both parts are 3⁄16-inch-thick steel and allowed us to drag the Jeep over a lot of obstacles.
