I installed a 2.5" teraflex coil lift and I just bought a new JKS front adj. track bar and was wondering if someone could give me a measurement from center of bolt hole to center of bolt hole to get me started. Thanks for the help

with your track bar off, bounce the front end of your jeep up and down a couple of times and it should almost be centered over your axle just with that. set your track bar so that it can be bolted on without any effort in this position. if additional adjustment is needed, this write-up should help out:

EDIT: looks like piginajeep beat me to it

 

So when I did it, here's what I did.

Put all the lift on, trackbar was one of the last things. With the tires on the ground and the weight on the tires I could see that the axle was shifted way over. So I had my wife turn the steering wheel and this cause the weight of the jeep to shift around. I had her turn it so it "eyeballed" to being centered. Then I just got down there and adjusted the trackbar to fit. Then I finished up with the alignment.
