Spring Over

[MudDober89]

Ok I have a 89 YJ with a 94 4.0 fuel injection set up. 4.5" Rubicon Express Exterme Duty Suspension Lift, 4.10 gears and Lock-Rite Lockers front and rear. I have managed to snap a spring center bolt on the trail. I have been looking at doing the spring over so that I wil have that added clearance of not having the springs under the axles. I am looking for input from others out there with YJ's as to what you think...

Not having done it myself, I have no practical experience on SOA, but I've know those that have. Most like it, especially for a mostly trail rig. Issues I've heard are getting the front steering geometry set up correctly and axle wrap on the rear. Also there are issues with drive shaft angles on the front, expecially if you have a low pinion 44 up front. There was recently an article in one of the wheeling mags that talked down about SOA on the rear...due to axle wrap, and repeatedly breaking their traction bar. They ended up doing a SUA on the rear and SOA on the front. They also flipped the u-joints so the plates are on the top. That leaves less dragging on the rocks...I might try that out instead of getting u-joint skids. I probably won't do SOA...but who knows.

Okdoekey... I am SOA'd coming from a 4.5" Extreme Duty... loved the RE kit.. flexed super nice, and drove really nice too. I did have the u-bolt skids. Not having driven mine yet, but have been in alot of SOA'd Jeeps I will take SOA anyday.

RE sells a nice kit for SOA. BUT... since you should alreay have the shocks, brake lines etc... all you need is the spring perches and shock mounts. Your front should be fine. Your rear might be ok depending how much room you have in your shaft now... and I assuming you have a SYE. MORE makes a great traction bar, and it is even know to run two. Either go with the RE reverse eye springs or two sets of stock rear springs.

... and a good welder...

You wont be sorry.

SOA is gunna cost about the same as a higher end SUA kit. If you do like I did you can do an entire SOA for under a grand. I did a freaking ton of research. I've driven my jeep a few times now and I can't wait to get it on the trails. Once I added my new front axle and shocks I'm sure its gunna be pretty sweet. My 35" tires don't even fill up my wheel wells

A grand?

Assuming that his lift is currently set-up correctly, he would only have to purchase:

Springs (Free: Stock to $600: RE SOA springs)
Spring Perches $80.00
Shock Mounts $5.00
centering pins $10.00
spring bushings $40.00
Traction Bar ($25 to $525)
Shims $35.00

So with shipping that is at least $300.

You can reuse your U-Bolts, spring plates, shackles, Brake Lines, Drop Pitman Arm.

If you can weld, then there you have it. If not, then yes, it will cost at least 50/hr ti "hire" a welder... but I am sure you can get a lift party going and be sure to invite a few welders. :D

You left out the $299.00 for the hot wings and beer

ehhh.. I would go the cheaper route of building a leafpack from junkyard parts. Maybe get it done for about $150 then for all 4 packs.

I might try to be careful and reuse the spring perches. If not, you're going to have a semi-competant welder put them on anyways, why not build a set? Could probably get the perches and shock mounts both done for less than $50.

Why buy shims? Why not just angle the perches when you weld them on to adjust for pinion angle?

You could easily cut that cost in half by doing a few of them yourself instead of buying.

I guess you're also forgeting SYE and driveshafts and brake lines

If he has a 4.5" Extreme Duty... he should have those things already. I know mine came with all of that, and I needed an SYE and shaft. You will also gain another 3-4" of brake line if you remount the hardline closer to the bump stop.

I had a 5" SUA on my last Wrangler without SYE and new d-shafts. I just had a t-case lowering kit.

Now that I'm SOA though I have my rear angle corrected so no lowering cases needed here :)
