The FX4 Has the tow hooks and there is a bracket welded on to hold to hold them but it's not there on anything that does not have the tow hooks.It is the Xipoqix one without the side bars put on. I 3D printed covers for it to clean the exposed side holes up. It mounts (mostly) flush with the bottom of the bumper. There is no clearance loss. I don't think its designed for an FX4, just an XLT. I assume there are subtle differences between the two underneath.
