Ok when my jk comes in, I'm thinking I want to get this lift, My question is, if I order the economy, everyone says to get the track bars aswell. Whats the benifit to the premium lift?? DO I need those other bars, or will the stock pieces be fine with font and rear trac bars? Whats the benifit to the additonal bars?

 

the "Premium" kit will allow you to "Dial-in" your WHOLE suspension to a perfection (longer arm, etc). IMO, get the economy kit first, since you can get the rest later as you save up some money.

As far as trackbar, with 3" lift, your axle won't be centered anymore. The adj. Trackbar will allow you to bring your axle back to dead centered.
