Mystery of the Leaning TJ

[Yellow RUBI]

I have a 06 TJ Rubicon, I added 2" spring spacers everything seemed fine, I changed the springs and spacers out for USED Pro comp. 2" lift springs, and added a full set of  rough country x-flex control arms. After two weeks of sitting in a parking lot I now have a Jeep that leans about an inch to the passenger side front and back.
The ProComp springs were suppose to be fairly low mileage.
What do you guys think is up?

Tell your passenger to stay off the Twinkies. 

used springs?

[JENSSEN]

You have the left spring on the right side and the right on the left.


But seriously Check your bushing/isolators for excessive wear or incorrect placement.

Mine is the same way!

Are the springs supposed to be different from front to back?  Maybe you have the rear springs on one side and the front on the other!?  I know that happened to me with my yj when I put used springs in it a couple years ago.  Never could understand why it always leaned to one side.  When I did my lift I figured it out pretty quick. 
Just a thought.

i think for a while there was a side specific coil for tj's. especially aftermarket springs. thay had the rr spring stiffer to hold u pbetter to the torque from the engine always wanting to squat that corner... or its cause they are used pro comp cheapo springs. just a thought...

Don't know if it's relevant to TJ's, but a lot of JK's lean to the left cause that's where the gas tank is.  All the weight is on one side.  I think JKS even makes an adjustable coil spacer to deal with it.

Well, the springs are different front to rear (anyone that has changed them will agree), with that in mind, the springs use one part number for the front and one for the rear.
There is a full inch difference from one side to the other.
I am thinking about getting some ACOS but that is not a the real solution its just a band-aid.
I weigh over 200 lbs and when I sit in the Jeep its not lvl.

where did you take the measurements from? ground to frame, or did you measure the coils. It sounds like a bad coil, if it was a wrong part in the wrong place, bad control arms or install error you would have noticed right  away. You could see if swapping the passenger front for Driver front coils drops the driver side or it stays the same, but you will have to allow some "settle" time before you will have an answer.
