High boy is 73 short bed 4×4 with factory 4" lift. Anything else is a jacked up ford.

A "highboy" or "Hiboy" is and F250 4x4 from 1967-1977.5 - you can see if its a "highboy" by the divorced transfer case, extra front crossmember, F26 vin number, and they are on the F350 frame - side note "highboys" are only on longbed frames. So "High boy is 73 short bed 4×4 with factory 4" lift. Anything else is a jacked up ford" is simply untrue.
