What is the benefit of running a shackle reversal? Seems that alot of the SOA Jeeps run with the SRS system. What is the benefit of the system? Downfalls?

Is one better than another? I heard Warrior is thinner metal and MORE makes a good kit. Doesn't look too hard to create one yourself.

I'll be doing an axle swap and SOA on my YJ, so now would be the time to do the SRS as well. Waste of $$ or a good upgrade? Seems like the theory behind the SR system is correct and Jeep actually has the front system working backwards...they must :smokin: some good :nuke:

I say make your own, and its well worth it. The only negatives I came across is you need to run a front shaft with much longer travel, and slighly more brake dive under hard braking. You will want to move the front axle forward a few inches to keep your tires from making contact at the rear of the front fender opening. A few extra inches is a good thing anyways. I can't say how it would be only doing the SOA w/o the reversal, cause I did them both at the same time, out-board springs, w/ waggy D44. I can say that it drives and handles better than it did, with 3" lift SUA. It also slides up and down ledges much better w/o the shackles in front:cool:
Just my 2 cents, but I think its the way to go.

I went with the MORE kit and YJ springs on my CJ. More travel in the driveshaft and less risk of bent springs on a SRS..

I'm SOA with SR, works great.

You will need a lot longer travel front driveshaft.

The biggest b!tch with the SR originally was when I was SUA. With arched springs the tire will come back into the body. I moved the axle an inch forward, that was not enough, and it was a pain in the a$$. Then I went SOA, same amount of lift after all was said and done (did other mods at same time), BUT soa my spring it completely flat. Now it does not move backward when compressing, it moves forward, and NO MORE RUBBING. Tres Cool.

So I guess I'm trying to say that if you are going to run flat springs SOA then the tire-into-the-body thing is usually not an issue, if you are running arched springs it gets worse the more the spring is arched.

There are lots of reasons NOT so SOA. And only one to do a SOA. Don't do it. Do a search on this.

Did you run high clearance steering with that? Moving the axle foward with a shackle reverse usually leads to high clearance steering problems.

HAHAHA what kills me is I can honestly say I've never had any of the problems bob extoles as inherent problems of an SOA..

I run SOA on my 83 CJ-7 with MORE SRS kit. I like it. it has not been an issue on my truck. i did however have a issue with my axle wraping so i had to do a front traction bar. but with a traction bar on a SRS you have to do it properly. here are some pictures of my setup:

it is a upsidedown shackle, the shackle now mover on the same level as the shackles on the SRS.

If your keeping the stock YJ springs when you do the soa, then dont bother with the shackle reversal. If you are going to use lift springs then go with the reversal. Flat springs naturaly move the axle a bit to the rear when they flex up or down, where as a lift spring tries to move the axle forewards as it flexes up and to the rear as it droops. All the shackle reversal does to improve ride quality is let the arched spring move the axle rearward when it flexes up as in encountering a bump in the road. On a side note, try to keep things as simple as possable, the SR will involve fabbing the mounts and hangers, new long slip driveshaft, fender interference or moving axle forewards, and possible tierod-draglink interference. How big a can of worms do you want to open? Doing the axle swap and soa is a fair size project to begin with, keep the shackles in front, drive it for a while and see how you like it. If your not happy after a few months, then go for the shackle reversal.

Just muddying the waters a bit more,:flipoff2:

ok go with the soa with the sr then use a waggy offset leaf spring to push the axl forward a couple of inches then you wont have any rubbing problems depending on tire size and get a little longer wheel base all in one long weekend that one took .04c:rasta:

I forgot. Why do you do a shackle reversal anyway?:flipoff2:

Oh no, this topic again already? Man how time flies...

Thanks for the help.

I wanted to do the SOA to clear larger tires. I am swapping in this dana 60 and 44 and the 3.5" SUA leaf spring lift will not clear at least 36's with any room for articulation. I thought the SOA would be a cheap alternative since I already have the springs. I didn't want to spend more $$ that I don't have on taller leaf springs.

I haven't seen too many posts on the negatives that Bob said about the SOA. Just heard that you are more likely to tip over, but with full width axles it will be harder to do that. Seems that most of the l/s Jeeps are soa.

I would run my current black diamond 3.5" leaf springs for the SOA. Sounds like the SRS would help prevent the tire from hitting.

I wanted to do the SRS because I have read things like what Chad and Kwranglin said: "if you are going to run flat springs SOA then the tire-into-the-body thing is usually not an issue, if you are running arched springs it gets worse the more the spring is arched."

What problems are you going to run into with the hi steer combined with the SRS?

Thanks for the thoughts...persuading me to hold off until I get this pain in the *!@ project completed. Just have to find out why not to go SOA...

When you find some REAL disadvantages you let us SOAers Know.

STOP!! and THINK!!

I've DONE this. You got it BACKWARDS. With a SR, arched springs will move the tire BACK into the body, not away from it. Think about it. As the spring flattens, with the fixed point at the front of the frame, the tire MUST move backwards because the length of the spring eye to eye is extending. I've done this, I know. With arched springs (like 3.5 BDS springs - I was using 4 inch RE springs) it WILL move the tire BACK into the body.

Buddy who thinks flat wrangler springs will move the tire back doesn't know what the fawk he is talking about. THINK about it again- when a flat spring compresses of extends, if the fixed point is at the front of the frame, the tire MUST move forward, because the length of the spring eye to eye is becoming less. I've got this setup now, and IT DOES.

I rubbed at the back of the body with SR and 4 inch lift springs. I do NOT run now with flat wrangler springs SR.

Stop and think about it for a second, maybe even draw it on a piece of paper. With arched springs, how can the tire move forward if the spring length eye to eye is EXTENDING as it compresses??

(finally a question I can answer)

I didn't say anything about SOA. Just the shackle reversal. Do the SOA. You will like it.:D

Hey Eric.:flipoff2: How's Colorado?:D Change your mind on SR's yet?

Is the loss of a bit of traction from the SR with flat springs enough that you'd notice?

With the flat springs and the SR wouldnt the axle assembly move easier to the rear instead of into the obstical as it would in a non-SR set-up?

I also agree that the lift springs would move rearward with the SR as ChadLloyd stated.

Later.

Aaarrgh, don't get me sucked into this ancient discussion yet again LOL :flipoff2: You have it backwards though. Flat springs on stock config move aft during flex (compression & extension). It's the arched ones that move forward on compression in a standard config. SR swaps the two and it boils down to personal preference and nothing more. Period.

:beer:

Oops... My post was contradictory to itself. I meant that the arched springs with SR... Is the traction loss noticable.

I will proof read my posts in the future. A big :flipoff2: to me!

Having done the SR .......

personal choice is right. Some times its better sometimes worse. Rides better on the street or washboards, if that matters to you.

If I had to do it over again, I wouldn't. Not because of anything bad, just that the 'good' didn't really amount to much.
Just my personal opinion though.

The main benifit I found, like stated above is the handling and ride. If you drive it on the street or roads at all I say its worth it.
