Does anybody have a list of specific differences between two identical models, one being F250 and the other F350? Mechanical, frame, suspension, electrical, etc. differences?
Or are they the same truck with different leaf springs and different GVWR stickers?
Otherwise identical? The best I can figure out, it comes down to three items:
1) The F250 with the 6.2 gas engine is fitted with the six-speed Torq-Shift G automatic transmission (aka 6R100). The F350 6.2 is fitted with the 6R140 AT (gas version). Models equipped with the optional diesel engine both get the 6R140 (diesel version).
2) Labels. The highest F250 GVWR label is 10K lbs, which is also the lowest GVWR label (artificially so) for the F350.
3) The rear springs, and even that's not totally clear (to me, anyway). Specifically, it looks like a base F250 is fitted with three-leaf rear spring packs, and the base F350 is fitted with four-leaf packs, but I don't understand note (6):
Depends on configuration. It's been hashed out a lot here. If you search, you'll find many threads. The closest a 250 comes to a 6.7 SRW 350 is if it has the HD Tow package. Between those two, the only difference is the spring rate of the main rear spring pack. Drop that or go to a gasser there are other differences. You'd have to tell us your exact configuration for someone to tell you all the differences.
Rear springs and Axle depending on engine choice F250 gas and diesel sterling F250 HD tow Diesel only Dana axle. F350 gas sterling f350 diesel all Dana.
F350 has a helper spring to take the extra payload. There was mixed responses on whether the f250 has 2" blocks or if they have the 4" that the F350 has.
Besides that, identical frame, axle etc. And then there is the legality of the F250 only being able to have 10k GVWR.

The blocks you mention were for 11-16. All the 4X4 trucks, 250/350/350DRW/450 have the same 3.5" blocks for 2017.
As to the helper springs, the 250 can have them too. They come with the camper package and the HD tow package on the 250.
So with the right packages, they are identical except for the sticker?
Good to know!!
Close. As I said in post #2, the HD 250 is the closest you can get but it's main rear spring pack has a lighter spring rate. Otherwise identical.
For 11-16 they could be ordered 100% identical with the camper package on the 250 as long as it shipped with the 4" block. This started happening in 2015 sometime on the 250's but not in all regions. There has never been a rhyme or reason on that one...

I don't believe that's the case. My take is that the F250's "largest" rear spring pack is four-leaf (i.e., camper package or HD tow pkg), but the F350's largest rear spring pack is the five-leaf configuration.
The F250 continues to be de-rated for GVWR on the sticker because in several states you are forced to register a vehicle over GVWR 10k as a commercial vehicle, even if it isn't.
I'm talking 2017 models, crew cab, 4x4, short box, gas engine.
In building them online, I think I'd select the "camper package" for the F250 because it's cheap and has more heavy suspension. But, if the standard F350 is the same thing, that's an option too.
We used to have special license plates for 10,000+ GVWR trucks, but I think that's done away with now.
I wonder why the F350 gets a transmission with "taller" ratios? That seems backward.
My F-250 has the camper package and !0,000/9,900 GVWR package. Their is a 100# difference in their rating between the F-250 and F-350. The camper package includes stiffer front springs, rear springs and stabilizer.

For this configuration, the differences come down to the AT and the rear springs.

The F250 camper package option adds a fourth leaf to the rear springs, stiffer front springs, a rear anti-sway bar, and the camper cert. An F350 w/ 18" or 20" wheels comes with five-leaf rear spring packs; there's no change to the rear springs if you order the camper pkg.
A nice thing abut the F350 is that you can get the heavier rear springs without having the get the camper package's stiffer front springs should you not want them. You can add the rear ASB later if you wish.

You can order a 10,000 lb. GVWR "paper downgrade" for the F350 (Option Code 68 D) which makes it less than "over 10K". It's a no-charge option, and there are no mechanical differences.

There's an ~5% difference in the first gear ratios, but the other five forward gears are all very close. Both models got the 6R140 for several years; the lighter-duty 6R100 was just introduced for 2017. I assume it's cheaper to build, and it may be part of a marketing strategy to better differentiate price and specs between the base models of the F250 and the F350.
