I drive a 1996 f-150 singe cab 2wd, I was orignally going to get a 2 inch level, but I was wondering if I could just replace the coils with f-250 coils, and the rear leafs with f-250 leafs? I know its possible but would there be any additional modding?

 

You need the shackles and hangers for the wider leaf springs.

 

The 250 coils work great. That's what I am running. Just needs an alignment and I recommend longer shocks to get full travel.
