High Boy / Low Boy ?
Been trolling the sight now for a bit and have seen the terms "High Boy" and "Low Boy" used to describe some trucks. Yet I am clueless as to what the difference is. Could someone please throw me a bone as to what makes them unique from one another.
Thanks in advance.

A "highboy" refers to a 73-77.5 f250 4x4, where as a "lowboy" refers to the 77.5-79 f250 4x4's. the highboys from the factory actually sit roughly 4 inches higher then the later model f250's. hence the term. Other differences in include 2.5" inch front springs that are mounted to a crossmember in the front of the frame, low pinion front big hub front axles, and divorced transfer cases.

The highboy is simply the most awesome truck Ford ever built 
They also only came with 4.10 gears, the fuel tank was located behind the seat and they had a narrower frame that regular ford pick-ups.

All good info, just go to the link to get it ALL.
Pretty sure you are wrong, the 73-79 front springs are all 3" wide, its the rear that are 2.5.....in the 67-77 range I do believe.

Yes I agree for the front 5 to 6 leafs 3" for a HB and 2 leafs 3" for a 78/79 lowboy.
2 1/4, 2 1/2.... at least I was close? I was thinking they we not 2 1/2, but was not sure, thanks for the correction.
