A: On a 2007-11 JK, at bare minimum, you should have a set of 3" coils, bump stop extensions, longer shocks, rear brake line extension brackets, new longer rear sway bar links (factory links can be installed up front), adjustable front track bar and rear track bar relocation bracket. Optimally, I would recommend adjustable front upper and lower control arms as well as they will help you set your caster to the appropriate angle it needs to be. Also, if you have a 2-door, adjustable rear upper control arms and a new double cardin U-joint style drive shaft would be highly advisable.

On a 2012-Up, you will want to install a new front drive shaft regardless if you have an automatic or manual transmission. Assuming you install new, longer shocks with your lift, the extra droop you will see at a flex will cause the slip shaft boot on the drive shaft to tear. However, that is just one problem you will encounter. Even if you install exhaust spacers or relocate the cross over, the CV boot at the output shaft will be sitting at a significant state of pinch and this will cause it to fail prematurely.
