Hey Preppy
You wanted to know the difference between the F-250 and F-350? Here it is (I found this in the article section):
What is the difference between an F250 and an F350 (2003-2004)
There are 3 differences between the SRW 250/350...
1) F-250 vs F-350 badges
2) 2" rear spacer block in 250 vs 4" in the 350
3) *most important* GVWR for F350 SRW is 9900 in most states and the F250 8800 in most states.
From 99 to mid 2001 the srw trucks came with a Dana 50, Ford started using the Dana 60's on all F250/350's from mid 01 to present ,the front axle is identical on both trucks, including springs.
Springs in the Source Book are EXACTLY the same:
