Frames and axles.

[MarcusMiller]

I've read on another forum that the only difference between the F-250 and F-350 with the 6.4L is that the F-350 has an additional leaf in its rear axle spring. Any truth to that? I always thought from 3/4 ton to 1 ton there would be a bigger frame and different axles, though I know both use the same Sterling 10.5 unit out back. Dana 60s in the front correct?

Really, the only difference is a lower block in the back of the f250.

Springs vary depending on the package. The main difference is the block and has been for many years. Now if you go to a DRW, you will get a larger axle in the rear.

F250 has a 3" lift block under the rear springs. F350 has a 4" block(or is it 5?)

[JBB1970]

So if you put in a larger block in the rear what would you need to put in the front to keep the truck level? For instance if the F250 has a 3" block in the rear and you changed it to a 4" would you need to raise the front 1" or more or is here more to doing this?

Thanks,

Not sure about the newer ones, but the older ones...nothing. They just sat higher in the back. These trucks almost always sit nose low anyway.

The other difference is the GVW tag on the door, which is why a lot of us have the F350.

Or f250 I know in some locations the 350 requires special plates or stickers that the 250 doesn't.

Can be different even between just 250 models or just 350 models. I have the snowplow prep package on my truck and it sits higher than the identical truck without the snowplow package. If you go to a dealer that has a bunch of trucks parked in the parking lot style you will see a difference in heights of truck. No the parking lot was not the cause of difference. I guess what I am getting at is there are multiple setups (3-5) I would guess within the same model year.
