that Reese hitch is designed for a frame trucks, and the X is frameless... a few weeks ago i transferred the OE hitch from the 4.6 to the 4.8 - there are many more parts involved than what is pictured on the Reese picture...
besides, it is reaching under and attaching where? in that area of the X there is battery pan, which is a sheet metal... you don't want reap out the rear end of your X... lol... there gotta be pics of the OE hitch somewhere on this site... take a look, compare...
