There is no difference between the front springs of an equally optioned F-250 & F-350. The spring rates are dependent on motor & option packages (heavy service, payload, snow plow, and camper packages to name a few).

Well I was curious if the springs from an F-250 would work for my F-350.
The engine is exactly the same. The f-250 donated its engine to my F-350.
I figured they look the same, so they probably were.
As for the package details? I have absolutely no idea. My f-350 was set up with a utility bed. (Those big ugly square boxes with a million doors.) And the F-250 has a normal bed on it. I'm not sure if the spring rate would be different for the F-350 because of that. But I only really need to know about the front end. I wouldn't think a package detail would really influence that.

Maybe I'm wrong but I thought F250 and F350 front springs are different... the rear ones are mostly the same only with bigger blocks.
My F250 was borne with springs negatively arched... when I bought my donor F350 truck for my D60 swap it had front springs that were positively arched... every truck I've seen is like that. But I am talking about the 86 to 96 F series trucks...

I'm fairly sure the arch is the same. Barely any really. :P
Thats kind of what I was interested about though. I was looking to build spring packs with the F-250 springs. I don't want my F-350 disessembled for awhile getting in the way of things.

Haha. I'm kind of jealous. I just looked at the F-250 yesterday and noticed the passenger side spring is messed up. It has kind of a wavey look.

86-96 F250 4x4's have negative arched springs from factory /\
F350 4x4's have positive arched springs factory \/
This is a fact with the 250 I have (which is EFI 460), and the F350 Dana 60 that's going under the front. In the rear, overloads and blocks are most of the difference, unless its dually.

The arch is different, and the TTB springs have about at least double the spring rate of solid axle ones... With a solid axle bolted to them they will ride horrible and not flex at all... That's how the front end of my big truck sits right now...

Thanks.
The arch on my f-350 is like.. zero haha.
The f-250 looks as if its supposed to be negative, but it kind of goes both ways, like I said the passanger side spring is kind of wavey.
and I got just regular springs...

on both the 88 460 5 speed powered F250 and F350,and 88 diesel 5 speed powered F250 and F350's i scavenged for the D60's to swap into the 250's, the trucks had the same identical springs in the fronts.
same arch, and same weight rating each truck with the same engine.
in fact, the 88 460 truck had one 250 spring and one 350 spring in it, because each truck had a broken spring. so i just used the 2 good springs.
