rear end is riding low on the right side. what could cause this?

The previous owner installed a Rough Country 2.5"suspension lift and I think a 1" body lift. The rear passenger corner is sitting about 1-1.5" lower than the rear driver side according to the rough coil spring measurements I took.
I have installed the rear track bar bracket for 2.5" suspension lifts and just replaced the rear coil spring today.....No apperant improvement.
I don't know if this is normal, but the rear spring does not run in a straight line top to bottom. At the top the spring fits into the base leaning forward at an angle. Is this my problem? If so what is causing it? If that is normal what do I need to look at next???

The most torque is transfered to the right rear corner during acceleration, so having the right rear corner lower is fairly common if springs are old (or cheap). That is likely your problem, but you could take some pics of your rear suspension and post them up, and we'll see if we can spot any other issues.

Rough country and skyjacker hardware are both known for short lives.

Literally just put a new spring on today. No change. Just sitting there it's lower. I am not home now I will post some pictures tomorrow.

Here is a picture of both rear coils. They look fine to me. Control arms and sway bar look fine too. With the entire rear jacked off the ground and wheels off I took measurements from multiple locations and had equal measurements on both sides. But once lowered I am sitting 1" lower. On the high side I am sitting where I should be according to Rough Country so my focus is on the passenger side.
Could it be a bad shock? Would that have any affect on how it sits?
I have been told my Jeep might be heavy on that side....But why? It's pretty stock nothing aftermarket accept wheels and suspension lift.
Any suggestions would be greatly appreciated. Being off this much drives me crazy. It's an eye sore and I am worried about a mechanical issue that needs to get fixed.

With the Jeep on the ground, what do all four coils measure?

After the lift, did you loosen/retighten the control arms and track bars to relieve the stress on the rubber bushing?

Where are your bump stop cups?

My what? I am new to this Jeep stuff. But things and parts are the same on both sides.
Is it worth my time since changing the coil didn't change anything to try it on the other side?

Did you loosen the control arm bolts when installing the new springs, then retorque them after the install with weight on the springs?
You should have bump stop cups in your upper spring perches with jounce bumpers in them. They should also be spaced down to take the lift height into consideration. Without bump stops, your shocks will act as bump stops and will be ruined after a few hard hits. Look inside the upper part of your front springs (if they are there), the rears are similar. Maybe someone will post up a picture for you.

As jjvw mentioned, measure your rear springs with the jeep sitting on the ground and see if they are the same

I did not adjust anything with the control arms in anyway.
So I should these bump stop cups positioned at the top of the springs on the front and rear. And there should be a spacer as well in the front and rear because of the 2.5" suspension lift....???

I have measured the springs under load and the rear passenger is compressed more. That is why I replaced the coil spring to start. I thought it was sagging.

The first thing I would do is loosen (but do not remove) all the rear control arm bolts both on the axle and frame ends. Once they are all loose, see if your jeep leveled out. If it has, your problem was a binding bushing in one of the control arms. Before installing longer springs, they should be loosened, then retorqued with the weight of the jeep sitting on the springs.

If that didn't alter the height, check with rc and see if the springs are side specific.

You really need to remove the springs, install proper bump stops, and reinstall the springs before you retighten the control arms.

Has this jeep ever been in a wreck?

It has a wrecked title.
I will have to see what I need for bump stops. Then adjust bolts on the control arms.

Then it may have a twisted frame.

It's been awhile, but I finally had the spare time to look under my Jeep a little closer. I finally noticed the 3 middle body mount bolts on the passenger side were sitting at a bit of an angle. I had the local auto body guy take a look. He said the unibody was a little off. The frame measured out pretty good, just a little off on rear passenger side. They are currently working on it now. I am expecting to come out with a total bill of about $450-500, covering all measurement checks and labor to straighten it out.
