This will take care of your lean http://www.jk-forum.com/showthread.php?t=57502
Over the past few years dealing with JK's on a regular basis, we have seen a few JK's lifted or not that have had a lean to one side or the other.
We have now come up with a solution that will help alleviate/basis the vehicle back to level.
Simply measure the swaybar links that you have on your vehicle from center hole to center hole. Purchase the length needed from our website. Install them and turn the linkage (gold hex bar in the middle) longer on the lower side of the vehicle. This will help bias the vehicles swaybar to compensate for the added side weight or whatever else is causing the leaning.
These can be used on the front and rear of the JK, with or with a lift kit. We offer linkage lengths from 5.5" - 15.9" in 1.4" adjustable lengths. These can be used on all JK Models (X, Sahara, Rubicon) but are not disconnectable.
The links are Heavy Duty 3/4" Solid Hex bar linkages, zinc plated with 1/2" studded teflon lined heim joints.
These can be used as heavy duty sway bar links.
This should only be used for vehicles that lean slightly. Severely leaning vehicles should check for other issues before installing.
