My first impression when I saw the Arc One bumpers sitting ready for install was "The guy who designed these knows what he is doing". The bumpers looks great, the mounting points are solid, there is gusseting where it is needed, and the winch sits down as low as possible.
My only negative critique of the bumpers is that because the parts are plasma cut rather than laser cut some of the edges are rougher than you would see on some more expensive bumpers. That said, these are prototypes and Mike at Arc One assures me that production bumpers will have smoother edges in all visible locations like the gussets for the front bar.
* Note that the trailer hitch shown in the photos is a factory Jeep option and is not part of the bumper.
