so, i m about to pull the trigger on a 2.5" or 3" lift for my 09 jku! Here's my dilemma: one kit comes with just adjustable LOWER control arms and the other with just adjustable UPPER control arms. My question: is one better for adjusting the axle angles then the other, or does it not matter just as long as one of them is adjustable?

 

I choose the front lower to adjust caster.

 

Front lowers here too. Teraflex arms!! Much beefier than stock.
If u get uppers I think only the curries adjust short enough to adj caster. I would choose lowers.

technically, upper arms are intended to set caster and lowers the position of your axle. however, if you can only get one set, adjustable lower arms will do the job just fine by themself, are easier to install and will give you a greater range of adjustment.

 

If you can get the uppers and lowers, I would since you have to take it all apart anyways
