OK...I did a search on SOA's and it seems that there are so many problems to remedy with the SOA set up...the biggest for me is the center of gravity issue because it is my DD. I'm swapping in a dana 44 and dana 60-2 and want to run 36's with articulation.

I read on Jeep Extremes page that the guy did SOA front and SUA rear to maintain the center of gravity. Website was:

http://www.larks.net/2001/dual_purpose/index.html

He basically ran with National leaf springs front and rear. Up front, fabricated his own shackle reversal, with the front mounts tight against the frame for better clearance. The front springs are spring over axle for better ground clearance. In back, he mounted the five-inch longer leaf springs outside of the frame and above the frame's bottom line. This helps stability and gets rid of that pesky rear spring hanger that hangs YJ owners up all the time. The rear springs are "spring under," to negate spring wrap on steep climbs, etc. Rancho 9000's painted black were installed at each corner.

What about running the front SOA with stock Wrangler springs (and a shackle reversal?) and the rear SUA with the 3.5" BD's I already have or get 4.5" R.E. XD's???

Would that solve the center of gravity problem??

I know we've been thru this...flame suit is on...I need some new perspectives.

Thanks boys....

I still dont understand what your aversion to SOA is. What problems to deal with? Heigth is heigth, and you have pinion issues, etc no matter what. If you are that worried about SOA, run sway bars :rolleyes:

I really hate the idea of SUA and SOA on the same Jeep.....It's like your scared of SOA but since everybody likes it you will do 1/2 of your Jeep that way :confused: If you are uncomfortable with it dont do it. The way I see it though 7" or 8" of lift is 7"or 8" of lift.You will have things to work out either way.

maybe you will feel better if we tell you that most trucks manufactured have come off the line with soa. $hit if you can have a soa van for instance and it is stable, your jeep can be made stable. stop being a pussy and just do the soa and dont look back:flipoff2:

OK

Here is my .02

I have (had) a 89 YJ and i was installing an Ford 8.8 in the rear and was going to go SOA front and rear. Since the rear axle was ready to go in i just installed it SOA and ran the front SUA with my Superlift 3.5" springs and i liked it so much i kept it like that and didnt bother SOAing the front!

The SUA Superlift springs rode great flexed awesome and the steering was fine!

Believe it or not, the truck sat damn near level!

I am currently parting out the YJ but i thought the SUA Front and SOA rear was an awesome setup for a daily driver!

like everyone said, no matter how you lift it Center of Gravity will be the same. If you don't want spring over don't run it, but don't bitch if you don't have the flex you want. Sway is a matter of getting the right spring rate, be it spring over or under. As far as moving the spring mounts outboard in the rear I don't see why, the rear already is wider.

Get some springs that are stiff enough and flat, maybe even the RE springs, run a rear traction bar, and front swaybar. All the problems of a SOA except spring wrap will be a problem with SUA also.
