Dealer or factory installed option
 

Thats a ugly bush guard and never seen one before so probably aftermarket.

Yup that's a good reason no one has saw it before .........FUGLY

Can you imagine the wind noise that thing would make? It wouldn't be as bad without the top bar, but still ugly.

I don't know why, but I kinda like it. Idk why

I found out is it factory but its made out of plastic http://www.wjjeeps.com/runboards.htm

The only thing I see it doing is shroud the headlights and kill the area light in front, PLUS add aerodynamic drag. Forget about adding brush protection! It does give you someplace to mount a couple lights, though.
