I have brand new, in the box JKS front and rear track bars. I ended up going with the AEV High Steer and Rear Track Bar Tower and don't need them. The rear I did take out of the box and put on the Jeep, but before I finished installing the kit I decided to take it off and go with the AEV stuff. The front has not been opened. $100 each.
I also have the Currie front and rear weld on brackets if anybody's interested.
