How long will Stock springs last on SOA

I just got my jeep back on the axles yesterday after converting everything to an SOA suspension. I still need to install the High Steer kit I got and traction bar in the rear before I can drive it. I noticed my springs got pretty flat when I set it down, flatter than I expected. I was planning on adding a leaf made for SOA in a month or two since I expect them to get worn pretty fast like this. This is my daily driver. I know a lot of people say no SOA on daily driver, but I don't care. A lot of my driving is in the city here, but I am a fishing addict and wanted something I could drive way out into the middle of nowhere at some spots I know. I do wheel it about 1-2 times per month, but no rock climbing or anything, just mud and some steep hills for maybe an hour at most when I go. So how long will these last stock? Am I going to snap one of these driving down the highway if I don't change anything for a year, or is it something I would eventually break on the trail and not on the road? I honestly have no idea how much abuse these springs will take. Either way I am going to add a leaf since I cant afford the full spring upgrade. This SOA project turned out to be way more expensive to do right than anyone ever says in their write ups. I did everything myself and it still cost a fortune. So any advice on these springs would be great. Thanks in advance for any help you guys can offer.

Soa is very expensive, I do trails, and mostly rock. I'm very easy on the skinny pedal as I have a 5.22:1 low range. I don't do deep mud or sand. I started out with using my stock YJ springs. They lasted about 3 months then I bent one into an S shape. I bought a brand new pair of stock springs those last just as long befor I bent one. I pick up pair of stock XJ springs used the second leaf and bastered a pack together. Those did pretty good, they did look to flat. But again I bent them only cause I fel asleep and went into a ditch at 50mph. So stock springs will work but not very well. I see two options either add the second leaf of an XJ pack to your stock springs or buy springs built for a SOA like Rubicon Express 1.5" SOA springs. That's what I run now and like the ride better then I did with stock springs.

Just so we're all on the same page, stock YJ springs were flat from the factory with all of the weight resting on them.

Thanks Banks316. That tells me a lot. SO what I am going to do then is see if the XJ Springs will cost me less than the add a leaf made for SOA. Cost is what it is all coming down to at the end of this project. Does anyone know someone who used those add a leafs for SOA? I would hate to get those saving little cash and they are dead in a year.

There are some writeups on it but essentially as long as you get the right year then yes.

Did your buddy have a traction bar? I know that is supposed to stop that hop. I heard even with good spring you could get that with no traction bar.

I'm doing the Rubicon RE1445 upgrade myself because my springs front and back are all pretty warped/bent/etc. Seems like a solid deal for the money and those I know that run them are very happy with them.

Im very happy with my RE springs I went with the 6 packs front and rear due to how heavy my jeep is.
