Thanks, and yes it just bolts on over the stock cover. Mine is chrome, but it is the same as the original. And yes I have a stock track bar. There was nothing to remove, fits pretty tight to the cover, but easy to add. Yes remove the cover bolts, position the ring, and bolt up with the supplied SS bolts. If you are lucky, the cover will stay sealed.
The main function of the ring is the protect the front ring gear from damage.
