I'm not sure what it costs, nothing from those guys is cheap, but it also is functional and more than just for looks. Thinking lcog and big tires. As for the flares, wouldnt the xenon's still fit? I think the idea there is you can rub up against a tree, and they bounce back where as a metal tube fender pushed agsinst the tub/core.
Looked at a tj with metal cloaks once, think they are neat for sure, same effect as raising the fender. The way you drive like a hiney badger with his head stuck in a cup, you might want the hard core stuff.
