Get a Chevy truck spring out of a 86' or newer & incorporate it into your spring pack & trim it to fit, leave it alittle long to go under your spring that ties into the shackle, (right under it,not mixed into the pack).

The spring is about 1/2" thick where Jeeps are about 1/4" thick, this will almost eliminate the SOA wrap.

Not to mention it'll increase the stiffness of the ride.

take one of the small jeep spring out to compensate.
Just a thought,
