Is a 2011 10.5" direct swap into a 2002 ? Both F350s
Will it fit? Yes. But the 2011 spring are longer. And the axle is narrower, so you will need wheel spacers, which aren't cheap.
I believe they are 1.5 inches wider than 04 down axles. Watch for gear ratios as well. They started to change them from 3.73s on 08 and up trucks.
