All though I have not install my lift (doing 3"-3.5", still collecting parts) I did buy a TNT track bar. It is MAJOR heavy duty and for the quality, it was the cheapest I could find. There are a couple cheaper but they didn't seem as HD. This one uses a new frame mount for the track bar, that makes the stock one look like tinfoil. I think it was about $235 with the mount. It is adustible as well. Might want to check them out.
