I searched this forum for all high boy threads and found a few conflicts. So...as much as I hate to ask an old question, here goes:

I have found a '78 F250 Supercab 4x4 that the owner swears is a high boy. I have aways believed that 1977 was the last year of high boys. Is he right? It has a 400, auto, married transfer case, and he says it has Dana 60's front and rear.

I am probably going to buy the truck regardless of wether it is a high boy or not, I am just curious.

I think it would be called a lowboy, but dont quote me.

 

No, it is NOT a "highboy". Not remotely.

 

Since the term "Highboy" is not a factory term, I suppose that he could call it whatever he wants. As long as he has put a lift on it to make it "high". Just kidding. What we all here, so affectionately call a highboy, is a pre mid 77 f250 4x4. Plain and simple.
Sounds like a nice truck though.
Have fun in your new ride.

 

Look at the transfer case if its married (bolted to tranny) its a low boy if its seperate with a drive shaft between it and the tranny its a high boy

 

that is not true. while most hiboys have divorced transfer cases, trucks ordered with full time 4 wheel drive got mated transfer cases. a supercab is automatically not a highboy as they were not available until after the frame change in mid 77. the hiboy got its nickname due to the frame design which was different than regular trucks and was discontinued part way through the 77 model year. the hiboys can easily be identified by the ladder frame design which is a few inches narrower than other ford trucks. this means that many components that bolt to the frame are different. the most obvious is the bed as the mounting bolts are closer together. hawkrod

 

Not "all" full time four wheel drive highboys were married transfer cases> I had on that was an unmarried from the factory.

 

that i don't doubt, the full time 4X4's seem to be so rare that i doubt ford made any two the same! LOL hawkrod

 

just putting my 2 cents in. I've seen a 1976 F-250 with NP-203 that was divorced.

Is the ladder frame design stronger then?

I am trying to think why they would use the narrower frame on these trucks.

Is the rear axle narrower from wms to wms as well?

I have searched but not found enough information.

 

yes, most are divorced but not all. for some reason there are a few with mated units before the 77 1/2 model. and to answer the other question about the frames, it goes back to the 60's when it was designed to use existing componentry. the basic ladder frame design was used on all straight axle trucks including 2 wheel drives from about 65 on and they were narrow to clear tires on hard turns especially with the old big F350's hawkrod

 

i have a 76 highboy that is full time four wheel drive and its a divorced t case
