Does anyone know if the rear springs from an 86' F-350 Dulley will bolt up to a 97' F-250? I have an old F-350 with the 6.9L and 4spd that we dont use any more and i want to up the carry capacity on my 97'. If not the whole spring pack, can i take the overload springs from the 350 and the brackets and use themon my 250? just playing with ideas since i have the parts laying around.

 

I am pretty sure that the dually springs are 2.5 inch wide and not 3 inch like the SRW. I don't think it will work but put a tape on the dually springs to check. If they are 3 inch wide then it should not be a problem

 

If I remember right the cab and chasis F350 had 2.5 inch springs and the ones that came with a box installed were 3 inch.
