At this juncture, it is unclear what you are trying to accomplish. I am still building the database. My individual situation is going to the alignment shop to check the "Z" measurement as you suggested and I'm going to the dealership afterwards if I need new springs.
It is strongly recommended that you go to the Ford dealer for your information. I'm going to, but that's not what I'm wondering about. It seems the eBay seller is wrong on his listing and I'm confirming that suspicion with greater minds here.
The generic sales photos of random eBay sellers is not a reliable reference from which inferences can be drawn. Agreed!
You have a 2015, which means you still have a tiny bit of time remaining before Ford sunsets information and support on your 9+ year old model. That is not good news.
Ford generally ceases to support or supply parts for models after 10 years. The cessation of support and parts sales isn't sudden, but it is no longer sustained after current inventory of parts sells out. Chrysler seems to be the same way also. And contrary to what some folks say, there is no federal requirement for them to maintain parts for 10 years either.
All the answers you seek are at the Ford dealer. I agree, and after I get the "Z" measurements I will be heading that way.
I am just continuing to build the database with door stickers and the information is interesting to me as there is sooo much incorrect information in various forums, and they just feed back and forth on themselves until pretty much none of it is correct (especially on eBay). That's what I'm hoping to NOT DO with what I am finding and putting into the database. I'm keeping the door labels as reference and cross-check, so VIN info is available to find a specific "stock" front coil spring from the dealer with the correct VIN information. So far, I have about 100 labels and counting. I'm cross checking on VIN, Door Labels, and Window stickers for what options came with the specific VIN (example - extra heavy duty alternator) so the part number search is not so onerous and the other necessary parts can be located as well. In this instance, I am tracking on FX4 springs, shocks, versus engine type and options. That's why I was wondering what he was offering as for all years, but it's not. I just wanted to confirm as a sanity check - peer review so to speak.

I'm not sure what you are trying to accomplish here. I need to read the full thread.
the post you asking about the ebay link. That' not a coilover and it says its an air shock.
the second link is to a russian site/ listing

the post you asking about the ebay link. That' not a coilover and it says its an air shock The eBay listing says this coil is good for 2005-2021. How is that possible if the shock is not available in 2005? IOW, I'm confirming the listing is wrong. If you look at the picture halfway down the listing, the picture shows a coil mounted on a shock with a specialized fitting. The coil is mounted on the shock in the listing picture, not mounted in seat pockets on the frame. Hence the "coilover". Please see above.
the second link is to a russian site/ listing It's a listing site that shows auction results by VIN. That's the one I checked after COPART. I can confirm door label information and GVWR, GFWR, GRWR numbers and correlate them to the SPR code to confirm or deny Ground pressure lbs rating.
Here's another one: https://autoauctionhistory.com/autom...50_super_duty/
And here is COPART: https://www.copart.com/lot/61944964/...-duty-fl-ocala

I'm finding there is so much mis-information on spring data that I got frustrated with it and I'm trying to use known research methods to get results that are verifiable, true, and traceable to the original source. You know, "show your work".
My questions do not pertain to my individual vehicle per se, but 2005 - 2016 FORD F-250 Super Duty. I am taking my personal vehicle to the alignment shop to have a measurement taken to confirm my suspicion of spring sag, then I will go to the FORD dealership and order new springs from them based on a VIN that I have researched that has the ground pressure lbs that I would like based on some excellent suggestions I've been graciously given by minds greater than mine on this subject.
It's a long story, but the thread covers it pretty well.

Thanks for the clarification. sounds like a frustrating project but great of you to step in and try to make it right.
I don't know much past a 7.3, just bits and pieces...so i'm of no useful help. I just caught the last couple posts and checked it out. I will have to go back through and check it all out. I hope you can get it figured out, best of luck

Data is updated with new information in case anyone wants to look at it. I have the information from approximately 110 door labels. Please include your handle from here so I know it's a legitimate request.

I have a request from "mhanson.1098@gmail.com" - does anyone know who that is?
They did not identify who they are or how they got to the page, so I'm leery to grant permission.
Thoughts?

Whenever working with Google Docs where editing access is given to others, ALWAYS run a parallel doc that only you have access to, and always create a CSV file (or whatever method you use to transport spreadsheet data into another spreadsheet program) into a local spreadsheet software (like Excel, or Numbers) other than Google, in case someone does something, inadvertently or otherwise, to the semi-public document where wider permissions were granted.
We have had more than one member doing good deeds for the community using Google Docs for crowd sourcing info... become devastated when Google (or perhaps a participant with access) unexpectedly deleted or deactivated (since I didn't see it personally, I don't know what happened) the entire spreadsheet.
So having a safe spreadsheet that only you can read and write, having a baked spreadsheet that others can read, but cannot write, and having a dynamic spreadsheet that others can contribute to, reading and writing, will insulate your investment of time, effort, and initiative from any accidental (or malicious) loss.

How to measure Ride Height per FORD.
This will allow you to determine if your springs are "sagged". Dimensional information is provided by FORD as well (NOTE: This is for 2025 F-150 as an example - so you will have to find your year and model information.)
