I currently have a 3.5 in Superlift suspension lift and a 1 in body lift on my 91 YJ. I'm looking for more clearance/articulation - so I'm thinking of one of two options: SOA or Revolver Shackles.
I like the idea of the SOA, but since I already have a lift I'm not sure how complicated the installation will become, i.e. considerations for drive shaft angles, steering, etc.
The revolver shackles seem to be a good alternative but only with respect to articulation, not clearance. Also, I believe some of the same geometric issues exist, but to a lesser degree. On the other hand, the shackles seem to be easier to install and less expensive.

Can you give me your opinion on which way to go, your experience with each, and any issues I will need to address in order to make the system work and perform safely?

Thanks in advance,

Alex

Hello;
I recently did a SOA and Revlover Shackle conversion on my CJ. The SOA raised my ride height by 4.5 inches and the Shackles give me a static drop of 6 inches. Shackles are very easy to install. Consideration is Ebrake and Brakelines lengths. the Driveshaft normally will not need to be lengthened, however the catch is the angle, my static ride angle is 20 degrees and full droop is 30 degrees my driveshafts start to bind at 38 degrees thats plenty of extra angle available. You will need to know where you driveshafts start to bind up.
The SOA is easy to do but time consuming. The quality of the ride it great compared to stock spring under. Issues to consider here are Axel Wrap and potential steering issues. Again easily resolved with the proper parts. (Pitarms etc.)

Thanks for the response. I was beginning to wonder if any body was reading my initial post. I do have some questions:
1) Did you do the SOA on your CJ with the stock springs? If I were to expect the same lift doing the SOA on my vehicle, it would be 7 inches of lift, plus one for the body-a bit too high for what I'm looking for.

2) How do you determine the angle at which your axles begin to bind?

Thanks again for your response.

The SOA springs i used came from Rubicon Express they make a leaf that is wrapped at the eyes differently, just for SOA applications.

As for the driveline just detach it from the rear end or front and let it sit in a natural position, now rotate the driveshaft it should bind, due to the new angle, take your angle finder, this is a cheap tool sold at pepboys etc. measure to seee what this bind angle is. write it down then elevate the driveshaft to a point where it doesnt bind this would be your limit. Using the center nut of the yokes as your reference point. Measure the distance from transfer yoke to rear yoke, now Attach the Revolvers and take a new measurement using the wood dollrod or something that will give you the new angle from transfer yoke to axel yoke. Using the center nut of the yokes as your reference point. This angle should hopefully be less than the previous measurement for binding. If all goes well with the angle next is the shaft length take the measurement at full droop. Using the center nut of the yokes as your reference point. This shouldnt be excessive if all is well.
