Yah, what green-machine said. I know the Teraflex 2.5" kit comes with everything you absolutely need and nothing that you don't need. I don't like the idea of the rear trackbar drop bracket putting more stress on the factory bracket that it connects to, so I went with an adjustable rear trackbar instead and ditched the bracket. If you're going to do this, then I guess the trackbar bracket is garbage, but you'll still save money by buying the kit. And although they're not absolutely necessary, I also added the front trackbar and front-lower control arms for proper alignment and better handling.
