AF990 on F350 CC SRW
OK, so I've spent gobs of time reading about weights and trucks and what to do and what not to do. I've noticed many DRW owners have 9 foot campers and many have 11-12 footers, I've witnessed a Dodge...
Forum Discussion
Yeah... that difference between a 2004 F250 and F350 was HUGE...
I tried to put in a link to an article from Ford Trucks but the forum didn't like it. Below is the text from it comparing the F250 to the F350 for the 2003/2004 model year. Now looking at physical differences between a say a 2004 and 2005 F250/F350 would produce a much bigger list than any F250/F350 comparison within a model year from everything I've looked at and options on a truck have far more delta on actual capacities than the badge on the side of the truck. 2wd vs 4wd, gas vs diesel, srw vs drw, camper option (add overloads and sway bar) vs no camper option, etc.
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:
