ok so since i have owned my truck and it hasnt been long i have seen a dozen or so threads on it and every one there is a different way to do it. and just as many reasons to do it or not to. though the one way i havent seen is just swapping out the frame with one from a f350. will the frames even swap?
i have a 94 f150 xtended cab 4x4 shortbed. now i havent found a f350 in this configuration but i have found 96 f250 to have this set up. but are they sas or ttb. could say a f350 single cab 8ft bed frame work. is there anywhere i can find the different dimensions of the frames.

now i am not planning the swap. this is just a subject thats been bugging me and since i am new to 4x4's i wanted to bring it up.

 

You could swap the cab to the new frame, but I think it would be easier to put the axle on your frame. Not sure about the cab and bed mounts, but I did use an extended cab shortbed driveshaft in my regular cab longbed so that might work.

 

yes the frames on most of the trucks are interchangeable. i'm running a 86 f250 chassis under a 95 f150 body and engine.

the f250 is a ttb( it will not bolt to the f150 frame, and the f150 ttb will not bolt to the f250 frame.

you wont find a f350 extended cab short bed i've never seen one so if they are even out there they are RARE.

you could just the f250 frame and later on switch to a f350-dana 60 front axle later, they swap right in.

 

i thought some of the 250 frames were straight axle

 

nope not until they switched to the new superduty body in 1998.

and they didnt even offer a strait axle f350 from 1980-1985. the f350's had the dana 50 ttb.
1986 they went to the dana 60 in the f350 and the f250 you could get a dana 44 ttb or a dana 50 ttb then in the 90's the f250 got the dana 50 ttb only.

 

4 wheel drive f250s have solid axles 2wd drive have ttb i have worked on both

 

I've been thinking about doing this next summer/fall but how hard is it to swap them out? How much fab work and welding would you have to do it or is it a relatively easy swap?

 

you have huh? do you know the difference or even what TTB means??

tell my f250 4x4 that it is wrong for having a TTB then.

from 1980-1997 f250 trucks never came with a soild axle from the factory.

 

i do know the difference between the two systems i have seen a 97 f250 and i think it was a 95 that both had solid axles though it is possible they were switched i didnt own them and cant speak for there history you obviously own one though and can vouch for it better than i can i was mistaken just going by what i saw my apologies for the false info

 

this is what i have been able to find for the dana 60 on when ford used it.

• 1974-1979 F-250

• 2000-2004 F-450/F-550

now FordTruckNut you said a f 350 dana 60 will swap on to a f250 frame. now do you mean as a bolt in swap or one with fab work. also did the f350 ever come as a extended cab i am not adverse to going to a 8ft bed as mine has rust. i just know that when i am done with college and have a bit more income to play with i want to do this swap with as little fab work as possible.

1989-ford-f150 i have seen a wrecked frame replaced in as little as 8 hours once all the parts were there and ready. but that was in a shop using an OEM replacement frame.

i would assume that trucks with the same options it would be a direct bolt in. with using say, a frame from a f350 single cab with a 8ft bed under a f150 extended cab 6ft bed work? would the mounts need to be moved or cut off one frame and added to the other?

i guess the real question would be how to do a solid axle swap with as little fab as possible?
