s code rear spring
I've searched and searched both Google and here and I can't find anything definitive...
I have a line on a set of springs off a 2003 F350 6.0 Diesel. The door pillar says the springs are VS.
V would be front.
S rears? I don't know what an S code is?
Can anyone please point me in the right direction?
I tried searching for "s code" (I used the quotes) and the results had all kinds of threads with a s in them.
Thanks!

I actually found a clue on sdtrucksprings.com. I searched for 2003 F350 springs by "spring code" and the S rear spring was actually on the list. I'm not suggesting their springs are the same or better or worse but the reference was notable. Their S code spring is a combo of their B code and another leaf, so it appears the S code is a B code with one more leaf. They seem to be pretty rare for some reason. I found very little about S codes on the internet except for a chart from CaryT that got reused a million times. Where is CaryT BTW? I couldn't find him on our forum.
It would be kind of cool if the S is like a modded B. I think I'm going to just buy the springs if I can get in touch with the seller and see what happens.
I know the fronts are V code, so with the S in the back, I think V will need some help from longer shackles.

Thanks, I really appreciate the offer. I'm having trouble getting in touch with the seller right now, so I'm not sure if I can get a part number off the springs. Typical Craigslist crap.

If and when I get the springs, I'll try to get the VIN number off the truck and I'll post the stamped numbers from the springs too. I do know for a fact that the door pillar says VS. Its a 2003 F350 crew cab 6.0 diesel (so I'm told, haven't seen it in person yet).

If it is this chart...
...then the S code you're looking at is a front spring. All the numbers on that chart pertain to front springs only.

Thanks Stewart. The S code actually applies to both front and rear springs. Confusing huh! There is chart all over the internet forums that I'm pretty sure Cary posted a few years ago. In that chart, S is listed as a front and as a rear code.

Interesting chart, if I read it correctly, it shows Excursion springs as dual rate? Either there's misinformation or the rates have been changed. I have done a lot of calculations of various springs and the rates (from drawings) are different that some of what was posted.

The S code is almost identical to a B code with a helper on top. The B code has a 7/8" higher free arch than the S code. I don't think aftermarket even makes these springs because they are so close to the B codes.

Would the B code result in more lift or would the S code?
Thanks so much with reps!

The free arch is when the spring is off the vehicle with no weight bearing down on it. If you got a straight edge, placed the straight edge from center of front eye to center of rear eye and then take a ruler and measure the distance between the straight edge and main leaf (the one with the eyes) you would get your free arch. Does that make sense?
7/8" is pretty minimal in my opinion but if your getting down the nitty gritty, yes the B code would give you, in a sense, more lift. I don't have a weight capacity of the S code but it looks to be almost the same as the B code.

I'll be sure to take careful before and after measurements for everyone - center of wheel hub to fender lip. Maybe I'll have the first modded S spring!

I was only clarifying that if you were referring to the chart I posted (the one from Bruce1954), that the info for the springs listed in that Excel spreadsheet pertain ONLY to the front springs.
There is no information on that sheet that includes rear springs.
I just didn't want you confusing the spring rate in that chart, thinking it applies to the rear springs.
It looks like Junior has you covered.
StewartH, at some point we were going to trade spreadsheets but I never heard back from you. No problem if you changed your mind otherwise you can email to rross455@comcast.net
Please PM me again what you need.
