250-350 differences?

I am looking at getting a super duty 2000-2003. Either a 250 or 350 PSD and don't know what the diff between the 2 are, like brakes, suspension or ride qualities. My son has a 2000 250 PSD so I have that reference

Can you guys educate me?

Thanks
Jerry

There is no difference other than GVWR on them. Same springs, brakes, seats, carpet and all that good stuff till' ya get to the dullie and you get more leafs in the rear.

On those years, the GVWR and GCVWR are the big things, but the 250 used 2" blocks in back, the 350 SRW used 4" blocks, the 350 DRW used the 2" blocks.

Other than that, same same

I don't think that is right. The springs are different in my 06 350 than in my 05 250.

Then again maybe I am wrong.

He's looking at '00 - '03. In the '05+ trucks, there are lots of other differences.

I have a 2002 F-350 Lariat 4x4
I bought it used a few months ago and I am very happy with it.
I wanted a 1999-2003 with the 7.3 PowerStroke vs the newer 6.0
I have an automatic transmission with the 4R100
I didn't see much of a price difference for a 250 S/D vs a 350 SD when I started comparing features and such.
My truck has an added helper leaf spring that most 250's do not have
pretty much all 250/350's have Trailer/tow package on them
I paid $26K for a loaded Supercab lariat(leather seats)long bed with 79K and a 2 yr ext warranty(Ford ESP)

Well, since you asked. And this is in the builders guide, just read closer.
https://www.fleet.ford.com/truckbbas...essd-ms_06.pdf
You may have to cut and paste that link or go to www.fleet.ford.com.

Larger frame cross sections on the 250 / 350
The rear axle size: 250 - 1.50" (6200 lbs) vs. 350 - 1.57" (7280 lbs)
The spline count on the rear axles: 250 - 35 vs. 350 - 37
With 4.30 gears you get the Super 60 front axle
Slightly different approach / departure angles

Got tired of looking at numbers!

Be aware that when people are talking block differences they are talking 4x4 (99% of the time).

4x4: 250@2" vs 4"@350
4x2: 250@0" vs 2"@350

I learned this the hard way.

What are the larger frame cross sections? Isn't it only applicable for the "chassis cab" or am I looking at something different?

The differences are the rear axles?

Okay, somewhat along this thread...I've a '99 F350 DRW. A few leafs were broken on the driver's side last year so when they were replace I had an extra leaf added to both sides. Sets level side to side but now I'm getting the nose sag. Anyway I installed a gooseneck hitch last week and am getting a trailer ready to pull the horses around in. The problem is that the bed of the truck is too high and the trailer is at an angle that most of the load is on the back tandem axle. My question: can I remove the blocks under the springs to lower the back end of the truck? (I cannot shorten the gooeneck tube as the trailer will run the top of the bed) Or will I run into problems with drive shaft angle or anything else? Yes I know that I'll probably need new u-bolts. Can the blocks be machined down some and then replaced?
