Question Half a Highboy?

I have a 77.5 f250 4x4 which I think might have just bumped my dog to my second best friend. However it appears to have 1/2 a lift kit in it (back-end, thank god) the front end is definatly lowboy. My neighbor stopped by and said the back looked just like his 76 stock highboy lift. He already sold it so I can't compare the two (or shop at the midnight auto parts store). The appearence of eveything looks like nothing was changed by the previous owner who had know idea what kind of truck he had. Has anyone heard of this set up?

A high boy has 2 1/2" wide rear springs a 77.5 low boy has 3" wide rear springs. All high boys had the gas tank behind the front seat.

Must be a low boy with 1/2 a lift kit

My guess now is it is a lowboy with a half of lift kit that some one put on early in the vehicles life. Everything points to lowboy. However I probably will be looking to get the other half raised. Could be the camper special but I don't see no stinking badges. (sorry for the bad movie quote)

Let me guess, you think it has a lift because there is a spacer block between the rear springs and the axle, right? The spacer has nothing to do with Hi-boy or Low-boy, it simply means you are looking at the back of a 4X4. The rear suspension of a 4X4 is basically the same as the rear suspension of a 2X4 but due to the fact the front end has to be raised on a 4X4 to allow for the live front axle the back has to be lifted to make the vehicle sit properly. There is no such thing as a factory lift, all 4X4's were built the same. There are different years and various changes but your truck is like every other of the same model. Also note that a Hi-boy and Low-boy are not significantly different in stock ride height. The difference is only about 2 inches or so. The difference is the way the components are mounted and the Low-boy was an obvious evolution for a better riding and more stable truck. Hawkrod

The biggest consern is the front end is two inches shorter than the back-end. The shocks and springs in the front are great, so I don't see a reason for the difference. There are two sets of springs in the back. I think they are over load springs, could that ex[plain the difference?

Yes, overload springs can easily lift the back up when it is empty. This is especially common on vehicles that were used for heavy hauling or for campers. When empty they run down hill. Hawkrod

If it isn't behind the seat it isn't original. All 66-77 (not 77 1/2) F250 4X4's had the tank behind the seat there was no option for any other tank from Ford. It is one of the worst shortcomings of these otherwise incredible trucks. Hawkrod

Yes those blocks are original, all 4X4's have them. And yes it is a Hi-boy. And yes the tank is not original and the bed is not original either. Ford did not have gas filler doors until later. The bed is probably a 78 or 79 and if your truck is anything like mine so is the cab and, and, and, and ..... these trucks did not survive in stock form for very long. When I got my truck I thought it was a 76 until I ran the serial number and found out it was a 77.5 (back then I not only didn't know the difference, I did not know there was a difference or what a Hi-boy was!). It did not have a single original body part. The only part of the truck that was original was the chassis less the engine but they did a good swap rebuilding it. I just wished they had noticed the bent frame! LOL Hawkrod

Yep it's a 77.5

Now with out a doubt it is a 77.5 with a overload springs. It has two doors one for each tank. very clean looking. This also explains my other neighbor who must have a 77 f250. It has a different gas tank set up (his is in the cab) with 77 badges. I pretty much live in 70's truckville. If anyone has or had both, which do you perfer? The both look good but I have to think the married transfer case has to be a plus.

You will find proponents for both styles of chassis. I am a fan of the 77 1/2-79 F250 4X4 which I might point out was the only Fullsize pickup choosen by 4 wheel and offroad magazine in their top ten best 4X4 list several years in a row. The 77 1/2 chassis is more stable and has all of the best features like the fulltime power steering, reverse rotation front end with disc brakes, and the maried transfer case. The fans of the earlier trucks like to point out that the chassis seems to have more flex allowing more motion for rock climbing. I love mine and have spent a great deal of time and energy making it the best it can be. Check out my gallery if you really want to see what can be done with a little wasted talent! LOL Hawkrod

Still Married?

Nice work on the truck, however if you are married (or still married) you are more clever than me. I love my truck and my wife, but some times i think they are enemies of each other. I've nicknamed the truck "the divorcinator". Once I get a paint job and 450-500 ponies under the hood I think they will live in happiness with each other. At least until bass fishing season starts then the trouble starts again. Thanks for the help "id"ing my rig.
