Uneven height on rear left corner...

My toy is a CJ-7 '86... recently I installed a new rough country 2.5 lift suspension+1.25" shackle (Daystar)... works fine but a little hard... anyway, recently I noticed that my rear driver side is dropped by 1 inch... I search for possible cause but had not clue...

Does anybody know which could be the reason? Could this be caused by a bad shock absorber?

Shocks don't support weight so a bad shock would not cause a sag. Check your u bolts and see if they may have worked themselves loose.

THIS!!

I installed my RC lift a few years back and when they arrived I noticed they had been re-bent in a press. They were quick to send out a replacement, however it hasn't been right since (pass front sags over an inch) I just wrote it off as crappy product and will replace it with a BDS lift when time allows!

Thanks for your comments... I will check today on detail the shackles as that one on that side has a little inclination, however not that much to lose 1 inch.. I will check if the bushing are ok...

Well looks like I do have a spring issue, I took measures, shackles are ok, seeing the leaf spring, right one has more curvature than left one.

Took some pics,

I hope it's the spring... but it could be the infamous "Jeep Lean" - made more noticeable by the lift. Albeit a pain in the ***, the best test is to swap the rear springs left to right and see how it stands.

You can't go by the apparent/current curves in the springs - the Jeep Lean WILL flex the springs differently.

Mine does that a bit, it has new springs under it but the real issue in mine is that I weigh about 320lb. so check your scale.

I thought jeep lean was caused by bad springs, different relax levels. Where are you suggesting it comes from?

Nope. There have been many people complain of the lean even after installing a brand new, high quality lift. Some have suggested there was a problem with the frame jig in the factory and its obvious quality control wasn't at the forefront with AMC so it's entirely possible.

Whatever the cause, I'm just thankful mine doesn't have it.
