To SOA or not to SOA, THAT is the question

I have a 89 YJ with a 2" spring lift and running 31"s
For the trails I want to run, I need more lift and want to run 33X12.5"s I was going to trade a guy in town my 2" springs for his 4" springs. He has already done the spring over and now sits too tall on the 4"s that's why he wants to trade. (I also know these 4" ride pretty rough).
BUT I also have a friend with a shop, that has done several SOA's, he suggest we do a SOA using my current 2" springs and if it is too tall we take out a leaf.
Right now I don't know which way to go????

IF I swap for the 4" springs:
The CONS are : I am worried my ride will get worse and I will later wish I had done the SOA (It seems like that is now the preferred lift)
The PROS are I know 33"s will fit perfectly and that my axles (D30&D35) should be able to handle 33" without too much concern.

IF I do a SOA using my 2" springs:
The CONS are : I am worried I will be too tall for 33"s, so I should run 35"s. I have to re-gear either way, so that's Okay too, but I am worried the 35"s will cause an early death to my axles which I will have just invested a $$$ into with lockers and gears. Also I will need my drive shafts modified (but am told that both can be made to size and balanced for under $200)
The PROS are a better ride, and it will be more FLEXY in the rocks.

(This is not going to be a "trail only" rig, it needs to be very drivable on the street but will see its share of trails rated 3 to 4 mainly rocks with 1 or 2 trips a year to the sand dunes)

So what should I do ? what would you do ?
I like the idea of 35"s! am I underestimating the strength of these axles ?

Re: To SOA or not to SOA, THAT is the question

do you still have your stock springs? What about SOA with your stocks, if you still have them? You'd get the clearnce you'd need and be back to a smoother ride withthe flat springs.... then you can sell either your 2" or your buddies 4" to pay for part of your SOA set-up....

Re: To SOA or not to SOA, THAT is the question

Nope, dont have them. The Jeep already had the 2" on it when I bought it.
But if I am hearing you right a SOA with stock springs is a better lift than 4" lift springs.
I guess I could probably find someone to buy/trade my 2" for their stock springs, and do it that way.
what about 35"s on the D30/D35 = bad idea ???

Re: To SOA or not to SOA, THAT is the question

35's + D30... Sure
35's + D35... That would be my point of concern out of the two....depends on how hard you are on the GO pedal. just remember, if you gear down for the larger tires, you're increasing your torque on those axles!

SOA w/ stock springs will net you about 4" lift and they will flex much better than a lift spring will because you don't have to overcome the arch in the spring on compression.

SOA- More flex, better ride than the 4" SUA lift, and you can stick on larger tires easily in the future when you want. (new axles would be 'needed' of course.. and other things that go wtih a larger lift, and tires)

I have stock YJ springs I just took out of my 93 YJ if you want em make me an offer im in California.. not worth it if you have to ship though...

hmmm, why dont you get rancho 1" over stock replacement springs like i did. that is a great compromise between 2" and stock springs
