Hi i have a 1976 ford f250 4x4
I was on bronco graveyard and they have super flex deaver springs for 73-79 f150 I was wondering if these would fit my highboy
Super-Flex Leaf Pack, 4 10 Leaf H57-Broncograveyard.com

 

The simple answer is no. They are F-150 springs not F-250. High boy rear springs are 2-1/4" wide, F-150's are 3" as far as I know.

 

x2 on what he said, those you are looking at are 3" wide and you need 2 1/4" wide for the rear of your truck.

You are looking for a High Boy specific set of rear leaf springs, only because the 73-mid 77's are 2 1/4" wide.

If you can find it on the web and think you have located something that might work, usually all the big companies have a tech line (phone #) and you can call and ask.

"Highboys had progressive-type rear leaf springs with 9 leafs that were
2 1/4" wide, compared to non-Highboy rear leaf springs, which were 3 inches
wide. Highboy rear leaf springs were 48-inches eye to eye."

Welcome to FTE, make sure you read those RED READ FIRST threads, TONS of information in there.

Now all that aside those you are looking at could be made to work, but you would have to change all 4 spring hangers that are riveted to the frame, and get 3" wide ones.

 

Okay so if I get f150 spring hangers they will work?

 

I just checked my springs and they're 3 inch

 

As stated earlier, those springs are not a direct bolt in. However, anything is possible if you are willing to do a little fabrication. I used to have a very similar pair of springs under the rear of my 75 highboy. They were Deaver F79s which are 5" lift springs for a 97-05 F150 and measure 2 1/2" wide and 58" long. I used rear hangers and shackles from a 78 F150 that I parted out and fabricated hangers for the front. I had two reasons for making my own front hangers. First, I wanted to mount the eyes lower below the frame to gain lift and eliminate the blocks. Second, which no one tells you when you buy new springs, the military wrap on the front eyes doesn't fit in a stock hanger.

A couple years ago I swapped those springs out for a pair of Ikon 2011 F350 5" lift springs that are 3" wide and 64" long because the softer springs didn't play well with the torque of my Cummins engine. They ride well because of the length and handle plenty of weight. For those I was able to use stock F350 hangers all the way around but I had to grind on the military wraps a bit to fit them in the front hangers.

If you want to get some good information on upgrading your springs with or without major modifications you can call Deaver direct and talk to Jeff. He is the guy who designs their springs and is extremely knowledgeable and friendly. He even knows quite a bit about old Fords and custom designed my front springs for me. I used to live a half an hour from their shop and have dealt with them in person many times about different projects. I'm not trying to write a commercial for them but they are good folks to deal with and I've always had positive experiences with them. I'd like to post pictures but I having seem to be having trouble getting photobucket to work today.

 

Did you measure your front or rear springs? The fronts are 3" but the rears should be 2 1/4".

 

The rears I'm pretty sure my truck has f350 springs and a block in the rear

 

if your springs are 3" wide in the rear you DO NOT have a high boy. that is unless someone removed the original spring packs and spring hangers and replaced them with low boy ones. but that would make your truck sit lower in the rear unless they added an extra lift block.

 

Yea it used to be a 2wd it was converted about 15 years ago using a mix of 76 parts and 79 parts but it has the highboy lift blocks and front springs so it's easier to label it as a highboy
The frame still the 2wd just modified

 

so its very possible that you have a 76 body on top of a 79 frame. ? this does not make it a highboy by any means. post up some pictures , that would help a lot.

 

1967/77 F250 4WD (High Boys) use the same 2 1/4" wide 6 or 9 rear leaf spring pack.

1973/79 F250 Regular Cab 2WD rear springs are 3.00" wide.

 

That would have been helpful information in the beginning. We're talking about a completely different animal here. Highboy may not be the best term for a frankentruck especially since it started as a 2wd meaning that the frame is completely different which is very significant. I'm curious, does it have a divorced or married transfer case?

 

It has a married c6 with a 460 bored 30 over

 

Dont think I have ever seen a divorced tranny before. Far as I know all trannys are married. Maybe you should start over with some real facts.
