Difference F-450/F-550

Hey all I was wondering what the difference was between a 1999+ F-450 and F-550 with 19.5 wheels?

I think the springs may be different. Most other parts are the same. They went to 10 lug in '04 or '05. I think the rear is a Dana 110.

Ya when I looked at a F-550 the rear end was huge! The rear calipers where about a foot tall
