anyone run SOA in the rear and SUA in the front???? Are there any probs with this???

Very stable ride I would imagine. The side hill problems of soa f/r would be eliminated. My ol man used to run a soa f/sua rear and it was very stable untill he wanted 36s. You would just be relying on the rear for most of the articulation. They do make some pretty flexy sua springs now that the technology is coming around.

thinking of doing a waggy front axle swap,, easier with sua, srs with 4" springs on front should about equal my stock spring soa rear.

I had my 65 set up like that for a few monthes. liked it much better after I went SOA on both.

It will not ever work

huh? Well ive heard of the other way around. One guy in a local club did this but only to eliminate axle wrap in the rear...

Well it does/did work on my YJ until I parted my Jeep out this past week...I ran it like that for all summer with no problems amd I could not forsee any coming problems other than you will go through rear springs more quickly than you will fronts

It DID work for a couple months. I just got the SOA front done today. Truckhaven here I come! The only thing I couldn't stand was the front end diving every time I hit the brakes.
Now that I've got the whole thing SOA, what's the "sidehill problem" I'm gonna have now?

Whats so tough about doing the SOA on the front? it is actually not hard at all, expecially sense it will be sitting right in front of you because its not in the vehicle yet. Wagoneer axles are very easy to do a SOA on, the only thing that might slow you down is steering. I say go SOA all the way around or your jeep will be unbalanced and the body will always try to stay parralel to the front axle

Well I dont know how much sidehilling you have to do in Cali on the trails but there is alot up here. When you are on the side of a hill driving across it not up it the body on soa suspensions tends to lean to the downhill side. The softer the ride the worse it gets. In some places here we have to hve people hang on the uphill side of a persons jeep to keep it from rolling.That is all, and the sua set up helps from doing that.


I dont recommend the set up this guy asked about, Id do a soa all around. It is easier to cut a perch into a waggy housing or do a little grinding and weld a perch on than to run sua and try to match ride height. That is going to be the problem. That and the fact that like someone else mentioned the springs will wear at different times and one or the other sag sooner. I just know some people run soa and sua and it works ok. Good luck.

You have a higher COG with soft springs that brings in body roll. That's all...

I just SOA'd my jeep from 3.5" black diamond springs in an SUA. Before I could sidehill at 50+ degrees and still be comfortable. Now, I don't know where the breakover point is.. I'll have to find out. I'll be shocked if it is still near that.

Let me clarify... it has little to do with being SUA....

highly arched springs are stiffer therefore induce a LOT less body roll in a side hill situation.

Bullshit.

SUA Front

SOA Rear (hard to see, but if you look closely at the rear springs, you'll see it.

Comments? Questions?

I ran suafront,soa rear on a 1982 Scrambler for several years and had absolutely no difficulty with the set up. The front springs were reversed with rear shackles and it drove fine on the street and also on the trails. Rear spring rap will eventually cause replacement or some type of axle wrap control but mine lasted over three years before I sold the Jeep. I liked the setup. Also had a 2" body lift and ran 33s. The Rancho front springs had nearly enough arch to keep things level too.
