Ok well my ideal finish jeep has

Explorer V8
C4 or c6
With unknown transfer case
Full size 5 lug D44 front
Full size ford 9" rear.
I haven't looked much into what that motor can push HP and torque wise. I was hoping for the low to mid 300 range on both.

although I'm doing more and more research. In my area there is a width max on most of the public 4wd trails. Not sure what it is but I'm guessing full width won't cut it.

Would you reccommend them being narrowed to the max allowed?

In that case 456s would be great. Over all width rule or?? I'd never cut down a full width axle. You can narrow it up with the wheels.

Ok thanks.

So until I get the v8 and larger tires.

Will I be ok (powerwise) with my 2.5l, 5 speed, 4.56's and 33's?
Probably 50% tread 33's as I will try to trade for them with my 90% 235/70/15's
I think that's the size of the top of my head (never can remember when I have metric sizes)

I'll be doing SOA at this point as well.

When the larger tires and v8 come I'll mostly likely do the 1.5 lift springs and some flat fenders or tube fenders

You will be fine. I am going to run 33's with 4.10 on my 2.5 and am not worrying. With bigger gears you will be close to the 31's with 4.10 I am running now and having no problems.

Hey guys really diggin all the info here, i had a 91 yj that went through all the problems as did i with my 1st SOA. i see guys posting vibe issues. i had them aswell, one solution is to (if running stock springs) compensate ahead of time for spring sag.meaning take a deg or two prior to welding the perches into place. that commonly prevents vibe. also some type of track bar is essential. i modded a skyjacker 5th link to work w my waggy 44. i ran stock springs then ome 2.5's learned a ton from doing things the wrong way. if theres anything i can do to help im glad to offer.

I had a full length add a leaf (Rubicon) added to my springs. I still have the traction bar I put in when I had stock springs and am torn on weather I should pull it or not. It slightly restricts flex in the rear and make some noise every once in a while.

its hard to say, the add a leaf will restrict flex but if your pinion angle is set to the current suspension height it may retard the angle too much. as much of a p.i.t.a. as it is i could say try a wedge or pull the alf. if i was back in de id give you a hand

I bet it still wraps if you remove the bar. Especially if you decide to upgrade the motor.

Thank's

Mr. Ibuildembig. I really appreciate you sharing your knowledge on the SOA and giving tips to others. I am in the process of putting a sbc in my 93 yj. My sbc build is a 383 stroker and my target is between 450 and 500 hp, not much to some but alot to me. I will definitely be hitting you up when I start my SOA !!

I am torn because it wont take me long to pull it, and I dont even have a motor for my swap yet (will be about 9 months-1year before I do it). I do use 4 Low primarily on the trails where I go since they are pretty treacherous. I just dont want it on there if I dont need it, but I dont want to have to take my springs back to a shop to have them re-arched. Like I said, it is a full length leaf that was added. Should I or shouldnt I?

Hasn't Ibuildembig done a pinion mounted traction bar? That is designed to prevent axle wrap and not bind up your springs?

Or was that someone else?

Mines not off the pinion, it's a one link wishbone.

I hope this doesn't come across as a really dumb question but...what are the benefits of a SOA configuration? ..and if one decides to do it what else should be considered in conjunction? It looks really cool BTW and you're pics and explanations are first class but..what's the real benefit..? if ya don't mind schooling the uninitiated..

Noooooooooooooooo!!!!! Stock axle in rear must go, unless you just plan on driving it on road. The amount of time and money it takes to convert sua to soa makes no sense to keep the dana 35 unless it stays on road. You may want to consider a lift kit if you want to do an soa cause you think it is cheaper. SOA is more work and $$$$. Other than that, stock TC is fine, and you do not need an sye.

Depends.

If you're just gonna drive it on the road with a 350 and say up to 36" tires, you can get away with a D30/Ford 8.8.

If you're going to 44" tires, geared to 5.13 and that 350 is spitting out 400+HP, you're gonna need something more like a D60 front and 14 bolt or D70 rear.

There's shades of gray all the way from one point to the other (D44, F9in, D60).

Help

So I just bought this 92 YJ, completely stock. I recently just put new Old Man Emu rear leaf springs and new rear Sky Jacker shocks because the ass end was sagging way too much. I am now looking to put a lift on it. Preferrably a SOA kit but i am trying to find out what you guys think of the different lifts and the best bang for my buck. If you guys can help, give me some tips and some opinions on what you think is the best route for me to obtain maybe a 4 inch lift.

Not *needed*, but recommended. Sometimes, in SOA Jeeps, you'll find that crossover steering limits the turns and you get bump steer (from the bar hitting the spring). I went with Rocky Road OTT kit so I never have to deal with that again.

What kind of setup do you use?
Or just stock?
Drop pitman arm?

Or are you using different axles?

With the soa steering is my only hazzy part.

Dropped pitman arm and that's it. Stock axles on the ones I do for customers, mine obviously are not.

I had crazy bad bump steer on mine with soa and waggy springs. That was with just a dropped pitman. Built a crossover setup and it is like a dream now.
