What is the difference between the 2? I know the 250 is 3/4 ton and 350 is 1 ton I mean single wheel trucks. Are there more springs in the 350? Or is the rear axel heavier on the 350,? I added extra leaf springs on my 250 so I have 8 on each side, rather than the stock 5 springs. So my question is would that make my truck a 1 ton now?

Business aquaintance bought last year a 2011 F250 SuperDuty, crew, 4x4, I think King Ranch, all towing extras,sprayed bed liner, front guard, Ford diesel, auto. about 58K !!!Insane!!
I feel lucky, got my 04 350, Ford 6.0 diesel, crew, all extras, King, auto, single rear, 4x4,guard, etc...in 5-07 w/82K miles and new michelines for ~23K!!! I'll keep her even when things starting to go wrong, or get another genltly used one.... I buy cars new, but not trucks at that price!

Jay, as Tom indicated on 2-wheelers it is springs and spacers,and badging, the older 3/4 4x4 with the split, twin I type front end as opposed to the 1 tons with solid, monobeam front-end 4x4 was the additional difference.
Duallys have a wider axle than the single axle do.
My question to you is what are you trying to do???
An air bag set up will increase the hauling a camper, towing a heavy trailer and not stiffen the ride so much you can drive or ride in it while empty, or or you ditching the pu bed and putting a really heavy service bed on. In that case maybe extra springs are in order & maybe a air bag setup.
A buddy of mine, has a air bad set up on his Dodge Mega cab 4x4. It is factory 1/2 ton truck that is all 3/4 ton running gear 8 hole wheels and Springs. His bags is set up so he can air them up at the back bumper he has had 20,000+ loads on and had about 35 lbs of air in them when hes is not towing or hauling he keeps about 5 lbsi8n them to keep them snug in their seats. Hope this helps.

> it was nothing but a spring spacer different.
Don't forget the decals!
Seriously though, the F350 rear axle supposedly had more splines internally. I don't think that it mattered, but that was enough of an excuse to adjust the GVWR numbers for State licensing requirements. Why would you buy an F-350 over an F-250 when they're the same exact truck if you have to pay twice the licensing fees for the commercial plates? I'll tell you, if you license the F-350 with Farm plates in my State, it's half as much than the F-250!
They're really the same truck for practical purposes as far as the single rear axle variety goes. It's a much different story for the pre-SuperDuty Ford trucks, though.

2" spacer blocks is it unless you go dually then there are a bunch. The early ones 99-2001 or so had Dana 50 front axles on both the 250/350. After 2005 the F350 srw is supposed to have 37 spline instead of 35 in the rear, but I think it only shows up in very specifically spec'd trucks,
Biggest difference besides sticker price is GVWR. Largest in bed gross weight for a F250 is listed as 10,000 LBS, for the F350 single rear 11,500 and 13,300 for a dually. And DOT, both US and state is going to go by the sticker on the door jam most of the time. You can add all the springs you want plus air bags and you are not changing that sticker. It's something to consider if your state is cracking down on pickups like some are. The 350 has a higher towing rating too which could indicate a stronger drive line but could be just the size/stopping power of the brakes.
If regestered as a farm truck and crossing state lines they now require US DOT inspections for the 1 ton and some states are requiring state DOT's on them too.

If were talkin 4x4 and from the 70's to 1997 than yes there are several differences in a 250 vs 350. In the 70's a 250 h basically had a heavier 8 lug version of a dana 44 in front and a 60 rear with less springs and smaller axles. A 350 had dana 60's all around more springs and bigger axles bigger brakes and calipers. Staring in the 80's till 97 a 250 had a Twin Traction beam front end and a 350 still had a solid mono beam axle. 350 had more springs and axle splines and heavier front ends with bigger brakes and calipers. from 99 till present not sure theres much difference in the two. a couple heavier springs and more splines on the axle shafts. pretty sure the brakes are even all the same on both. So yes and no on the adding springs. It mite have gotten you to the same hauling cap as a 350 but in BMV and DOT eyes its still has the GVW of a 250.

Axle spacer and GVWR on the door post are the two biggest differences between a 4x4 F250 and 4x4 F350 SRW.
obvious differences are badging and dually available for F350, which in turn means more wheels and wider box and increased payload / towing capacity.
At least on the 2000 model year, 3.73 was F250 ratio, while the F350 could have 3.73 or 4.10, 4.10 upped the towing capacity.
I have Firestone air bags on my F250, but as other have mentioned, no amount of extra springs, blocks or bags will change the door sticker number for a DOT person going by the factory numbers.
