I took mine off when I installed the lift kit about a year ago, and I can say it is unnoticeable. The front one, on the other hand, you will notice if you take out (this does not mean that you cannot have a dd without a front trackbar; it just means that the jeep will lean a little bit more when cornering). For the front, I installed a JKS telescoping trackbar, which I can let loose for offroading, and I am happy with it so far (its only been on for about 3 or 4 months).
