i have a 81' f250 axles and i not sure what i have it looks like a IFS but not solid but what is this? but mine are all spring leafs no coils... i need to know so i can keep this as my futrure refernce of what i m looking at and talking about or for lift kits ... mine are a 4x4 also
im not sure if its the same as mine but i have an 84 f-250HD and it came stock with a dana 50 IFS in the front and a dana 70 rear with leaf springs all the way around. Most none HD f-250's from 1980 to 1986 used the dana 40 IFS
EDIT:
your right it was a dana 44 not 40 sorry
EDIT Again:
if you wont to get rid of that IFS you would be better off going with a 1992 to 1996 dana 60 solid axle the convertion is easy and most axle shops will have the kit
my 85 F-250HD has a sterling 10.25"FF and a Dana44IFS in the front. (which sucks)
btw, you dont need a kit swap to a dana60 from an F-350. you just need a donor f-350. I want to swap it out, but I haven't found a Dana60, and i'm still try to get it legal on the road.
Are you sure? I'm almost positive the F150-250-350 used the same steering box. I did a SAS on my 94F150 and used a 90 F3504x4 drag-link which fits perfect on my 150 box.
I am pretty sure the boxes are the same. I believe that the pitman arm for the straight axle has a 1-2" drop. I could be wrong though. I guess the best way to find out is to see if you get a lot of bump steer
I have an 84 F-250 light, that I converted to a straight front axle. Stock was a D44HD IFS setup, and a D61 rear. Currently, the D61 is still spinning in the back, but I have a 3,500lb D44 from a 77 F-250 highboy. This thing is really beafy, almost as much as a D60 front, just about on par with a D50 front. I used Explorer Pro Comp rear springs from Summit, which gave me about 6" of lift. I then took two leafs out of the old rear pack, and added them to the front packs. I made my own front spring perches from 3" square tubing, notched to fit over the stock mounts. This setup makes the truck sit level, and doesn't make for a bad ride either.
