2005 F250 suspension on a 2002 F350?

[Gulfcoast]

I want to upgrade my spring suspension for coils. I found a 2005 F250 that I can get the axles, steering, and suspension from or the whole rolling chassis if need be. I currently have a 4in lift running 35's. I would like to maintain that height so I would need to put a lift on the new axles. Do I need to find an 2005 F350 or will the 250 suffice? I am not sure in the difference between the two. Is it just heavier springs?

I do not have a direct answer but they should be the same and just buy your lift springs, adjustable track bar and im not sure what else is needed on the 05 up suspension. Different shocks as those are pintops on the 05

axles are the same f 250 -350 srw
rear block is bigger on a 350
for a 4 inch lift on a leaf sprung truck '
I am not sure what size lift would equal what u have with yours now vs the coil

as I don't think they both had the same stock ride height ?
