Spring Code Question

I'm wondering if an F-250 with spring code 45A and and F-350 with spring code T4F would have interchangeable springs. Are the weight ratings the same on both sets of springs? They're both the same number of leaves, but I can't find a definitive answer on the weight ratings. Anybody know?

front springs? I don't know the codes for the springs.

Front springs are definitely different.

As for rears, I don't think there is any difference.

Ford generally rates their trucks wrong for what they are.

150's are heavy half tons and half tons.
actually 3 ratings for 150's in the 90's.

250's are pretty much a 1 ton with a different front end susspension
and 350's are 1tons.

So....

Oh. 350's have bigger lift blocks in the back.

Yeah, I guess I should have said that these are rear springs. They are both 5 leaf packs with overloads, so I don't know if that's all there is to it or whether there were different rate springs provided for some trucks and not others....I want to swap the rear spring packs out of an F250 into my truck since it seems I have one that is sagging or has a broken leaf in it or something. Truck sorta leans to one side and it's not the hangers or shackles b/c I replaced them last spring.

I though they were all the same except the 4" blocks on my truck, but I want to make sure before I plan on doing a swap.

I um,, ahem, bought an F250 parts truck.... More on that as soon as I get it home.

Yeah, this was more like a Craig's List deal that I couldn't pass up. Hoping to scavenge what I need for my truck and part the rest out on here, but I'm going to wait until I get it in my shop before I start listing things for sale. Going to take the motor for myself and a few other misc goodies, and sell what I don't decide to keep. Should be an okay deal. We shall see....
