Look at the section under "Supercab exterior dimensions" and the column that says 4x4 under the 5.5 foot styleside bed. Those are the dimensions for the Raptor. The 5.5 ft. bed is only available with the Raptor or the mid-box prep package on other trucks. Also, if you look at those dimensions, there's no mistaking it for the other F-150s. It shows the width as 86.3 inches and all the rest are 78.9 inches. The cab height, approach angle, track width, etc. are similarly larger.
