Re: leaf spring swap
are you talking about front leaf springs or rear leaf springs? Also F250 leaf springs on the super duties I know (99-12) are the same as F350 leaf springs only diffrence is blocks which F350s are taller blocks making it taller then the F250. So if you are putting the F350 blocks in then yes you will need taller blocks. Plus F350s have higher GVRW ratings then F250s only other diffrence in a F250 and F350 other then badges.
