Check out Tomken. USA made, strong and no rattles. I have their whole back (bumper, tire carrier, etc.) set-up and am really happy with it. Check out my Jeep profile for pics.
X2. I have a Tomken bumper with swing away tire carrier on my XJ. Built incredibly well. Well worth the money. Tomken is also a great company. Their shop is close to some of my favorite trails here in Colorado, so I buzz in when I can just to see what new things they're working on. I was there 2 weeks ago and they mentioned wanting to start making tube half doors for the TJ. Of course I offered to let them use mine as a guinea pig!
