Default SOA Setup

I am gathering info to help my dad do a soa on his 94 yj. We were looking at the kit from Rubicon Express that has the perches, brakes lines, pitman arm, tcase drop, trackbar bracket and shocker adapter bracket. I know he will need longer shocks but what else? Can he get by with the tcase drop and shimming the rear axle for awhile until he gets a sye and a cv driveshaft? Also will a soa clear 35 ok?

Save the money on the kit at put it toward an SYE. To do any type of wheeling he really will need one.

Perches are $12 a pair at Summit, tracbars are totally unneeded, and you can extend your sway bar endlinks with a little bar stock and a welder. (Or get discos or extended links from a kit manuf.)

You will not only need a pitman arm, but stock steering is going to hit the leaf springs. That is a whole nother thread :D

You'll need extened brake lines all around, and yes it will clear 35's. SOA is not easy or cheap, so don't let anyone try to convince you different.

Screw that RE SOA kit! SOA will open more worms and burn dollars faster than you can imagine. If he wants to run 35s, just get a quality spring-under suspension system which includes shocks & brake lines, bolt it on during a weekend and be done with it.

I completely agree with the SOA will burn dollars faster than you can imagine comment. I'm gathering pieces for my SOA right now and it's pricey. However, he's not going to be able to fit 35's with a standard spring under kit. I've got a BDS 3.5" lift kit, a 1" body lift and 1" lift shackles, plus I cut the fenders out and put TJ flares on. I could put 35's on but they would rub in the front unless I extend my bumpstops. 33's fit really nicely though.

ALso here is a good place to start if you want more info. Check into the links he has at the bottom as they will help too. Notice that he has a price list in his list, I would say that his cost out is a little low too. One because it several years old, and 2 because he left out some things, like a antiwrap bar. Also you stock springs are going to get worn out pretty quick, if you want new springs that's another $400 or so. Matt Osburn site (list at bottom in the links) is another good one.

Well, Talk to Swampjeep about this, he converted the old YJ to spring over after running a BDS 3-4" lift on it for a while. I believe thats QueenB's Jeep now. Stock YJ springs won't clear 35s on that Jeep in an SOA, and the weight will sag them. Even in my CJ-5, I beefed the YJ springs a bit with a couple extra leaves to clear 35s on my lighter CJ-5.

Going through the list:

Trac bars: Probably don't need them. There for road handling only

Shocks: Need longer shocks. I can tell you a good source for cheap ones if you want to work at it. (I got my 4 Gabriel Gas Rider LTs for $50 shipped, ~12.75" travel on all 4). Or just by what you want..

Brake Lines: Definately need longer ones.

Steering..dunno, talk to swampjeep. On my narrow trac CJ, I had no interference. Maybe run a style with a drag link that goes to the tie rod, not the knuckle.

Spring perches. A hole saw and a trip to the scrap rack at Pontiac Steel can get you all 4 for probably under $10. Make them strong. I 've had purchase ones that after a year of hard wheeling were starting to crush on both sides. 2.5 x 2.5 x 0.25" square tube would work well.

Springs.. CJ-7 rear springs, maybe?


Loved the SOA on my Heep.. would NEVER do a SUA suspension again. They will just drag you on the ground.. Will be doing an SOA or 4 Link on my flatfender once that build gets started. My Yota is SOA from the factory, so thats the way it stays..

the guy on Xtreme 4x4 did a SOA on his "budget Jeep" project and he claims it only costs about $50.00 to do. And....he scored a 900 something on the RTI. How could he be wrong? It was as simple as welding new perches!! :tonka:

I've posted this before, but here's my CJ-5 on the ramp at Attica.




SOA, round 1, my costs:

Spring perches: $10 for 4 at a trailer parts store.
Shocks: stock
Springs: Stock 1975
Driveshafts: $60 for two used shafts (I lucked out, and stock shafts from other applications fit the SOA perfect. Heh.. 19.5" driveshaft in a CJ-5... how long are those wrangler d-shafts?)
Drop Pitman arm: $70
Longer brake lines: $70
New u-bolts: $25

$235 for round one. Not bad, but the 11 leaf packs were too tall and stiff. I removed a few leaves then they S'd. I should have cut the other leaves to better lengths. Oh well. They were stiff, old 1.75" wide pre 76 springs..

SOA, part deux:

YJ springs: $50 for the set.

CJ-7 spring perches & hangers $80 (today I would make them myself, but I didn't have the tools back them.)
YJ shackles and new bushings: $40
homemade spring perches: free (trailer ones bent pretty bad)

$170 more.

Even with the flex in the pics, I was running some old 9" travel shocks and getting away with it. Narrow frame, didn't need much travel.


Now, if you did a comparable SUA lift, you'd still need to address the shocks, brake lines, pitman arm, U-bolts, and driveshafts, regardless.

If you buy new springs for SOA, then really the components in either case is almost identical. But the SOA generally will peform better off-road, and get you more ground clearance.

You probably will need a rear traction bar. I never used one, and never felt any hop or binding, but it did have wrap. See pic:

BTW, that pic above is deceiving.. it looks like I'm almost on flat ground.. this is a side view of a buddy in the same spot. Top of a 30ft LOOSE hill..

I'm doing an SOA on a scrambler (CJ8) right now and I am using YJ springs. I am also using wider axles, which means I had to outboard the springs....but thats a whole other project! The SOA has alot of parts you need to do correctly. Pinion angles matter alot! Steering is a hassle (you can do high steer, but it costs $$). I personally think SOA is worth it, but I would not try it unless you have the necessary tools and an experienced person who has done it before with you.

Feel free to ask any other questions you have pertaining to this once you get into it!
