Now, who can tell me really what the difference is between the F250 and 350? (besides the emblem that says F250 or F350) I'm talking late model too please 2005, 06 and 07.

Dealer tells me the front suspension is exactly the same from the 250 to 350. (this makes sense since it's always the same weight in the front).

He also said the rear suspension has heavier springs on the 350. I said does it just have a higher block or are the actual springs different. He said the actual springs are different.

Now I know that everything else on the 250 vs. 350 is the same. Same driveline/axles etc... (I'm talking single rear wheels here of course.) Unless there is something I don't know about. So if this is really the case, it's just some rear springs that make a 350 a 350.

Do you all know of anything different?

I took an 07 F350 for a test drive to see if the 350's ride was rougher. Didn't really notice much of a difference over my 03 F250 (although not exactly comparable, as my 03 has leaves in the front).

So, is there anyone out there that knows for sure about the rear springs? I was wondering if it was maybe the same leaf pack, but then has an overload spring that starts taking over, that way it rides soft while the truck is empty.

Also, are they still putting the same suspensions in the front of the trucks whether it is the gas engine or the heavier diesel engine??? This way the diesel trucks sag in the front and don't look right? Anyone order the heavier front suspension upgrade when you ordered your diesel truck, and did this level your truck out???

thanks,

 

Front axle, same
Dana 60 or Dana Super 60 with 4.30 ratio

Rear axle, different, both Ford 10.5”
F250 1.50 diameter, 35 spline (diameter is slightly smaller at splines)
F350 1.57 diameter, 37 spline (diameter is slightly smaller at splines)
V10 and PSD have a 3-pinion differential, the 5.4 has a 2-pinion differential

Brakes, same

Frame, same

Front suspension, same

Rear suspension, same springs
F250 w/o camper package, heavy service suspension or snow plow prep 6100 lbs
F250/F350 same, 7000 lbs
***The difference is the overload spring, included with any suspension package on the F250. Springs are the same between the trucks, the F350 comes with overload as standard***
There is a taller block under the springs on the F350 that increase ride height by approx 2".

The front suspension is computer selected depending on options, gas, diesel, CC, SB, etc, etc, but the same between F350 and F250

Tow ratings are the same between the two (obviously different between engines and gear ratios, but not dependent on F250 or F350)

Payload is different between the two

 

[QUOTE=Ace!]Front axle, same
Dana 60 or Dana Super 60 with 4.30 ratio

I have seen/heard about this axle in the past. I was wondering if anyone knows what it is and what the differenences are ?. I can't find any specs or info on it .
Thanks

On a similar note, does the F350 cost anymore than the F250? The reason I ask is when I go to the Ford site and build and price a truck it makes no differentiation between the two. It doesn't let you pick one or the other.

 

All I know is the Super 60 is wider & has a higher GAWR and only comes with the 350 & above chassis cab. It is not available for the 250.

You can tell which trucks have them as they have huge, factory, front, fender flares.

 

The Super60 has a 10" ring/pinion and is used in the F450/550

 

Can anyone shed any light as to the difference in ride quality? I can't get a new V10 equipped F250 in NY but can get an F350. My only concern was the lack of ride quality.

here are some of the 13 pages of threads I got when I did a search of titles only. Hope this helps you out. There was talk of Ken disabling the "search" function for non supporters, I don't know if he did that or not.

 

I just traded a 99 F250 supercab for an 06 F350 crew. I really don't see any difference in ride quality. I wouldn't hesitate to go F350. I went F350 because of the heavy loads I carry once in a while in the bed. Got the camper package also and the truck carries a lot of weight very well.

 

No, not true. The Super60 is used in F250, F350 if you get the 4.30 ratio, it is the same width (although, really the Dana 44/50/60, etc has to do with the differential or ring/pinion size, not the width of the assembly). You can get a Dana differential in any width (through aftermarket companies).

Thats kind of what i heard also, But was told it also comes in some snow plow
aplications. The Rumor i head was that The Super 60 is in the tow boss with 4.30 / and SRW with 4.30 option. Is there any Physical way to tell or a axle code i wonder ?

Ace,
Thank you for that information. Wow, that's interesting.

Glad to see Ford does make them different. I guess the pinion shaft diameter in the rear stays the same though, too bad, cause I twisted mine off in my 250 pulling my trailer with skid loader. Good to see the axles shafts are bigger and more splines.

Nice to hear that ford puts in different front springs to accomodate for the different options.

Maybe they didn't do this stuff before, cause I swear my 2003 diesel f250 sags in the front and gaser f250s don't. I did buy additional leaves for my front (to level it out), but never got around to installing them. (anyone want them by the way?)

I know from making an order on a 2007 truck, they won't let anything but a 3.73 rear in the truck if it has the 6.0 diesel. I hate that, cause I want bigger tires and now I'm going to have to change the gears to 4.10s or 4.30s later. So, I guess no "super"60 option available to me, if the "super-60s" have 4.30 gears.

 

I just bought an 07 F350 RC 2WD. The truck I test drove was a crew and I cant remember if it was a 250, I had to factory order as my config is hyper rare. Anyways mine is rough as h*ll. I am contemplating taking a leaf out of the back, but because mine is a RC it is allot lighter than the other configs. That said the reason I went with the F350 was to get the 18" wheels (which further add GVWR) and to get the higher number on the sticker on the doorjamb. There is anouther thread on here about the legalities of overloading and I am a big believer in staying within the Ford spec. Your call on that. You are correct that it only has a higher rear spring and axle (that can be a big bonus too depending on your useage). Oh I got the camper package too, maybe that is why its so rough?

 

Okay..I stand corrected ... somewhat.

I didn't realize you could get it with an F250. But I still have my doubts. How would one order an F250 with it?

I understand it comes with the Tow Boss package (which includes the 4.30's mentioned above). But you can only get that with a dually.

I realize that you can get Danas in varying widths but was making the comment that you can tell a Super 60 by the factory flares.

 

It has to do with the ratio, 4.30, that's it. The 4.30 ratio *was* only available with a gas truck with V10, but then they came out with the Tow Boss package, which is the PSD dually with 4.30 ratio (you can't get a dually with 4.30 unless you order the Tow Boss package). So, no PSD or 5.4L will have a Super60, UNLESS the PSD was ordered with the Tow Boss package.

So, if you get an F250/F350, V10, with 4.30 ratio you get the Super60, OR, if you get the Tow Boss package you get the Super60 (all dependent on the 4.30 ratio), OR if you order an F450/F550 you get the Super60 with any ratio (4.30, 4.88, 5.38). BTW, I took this from the builders guide.

Gotcha about the width, and the flares. I love that look by the way.
