The plastic fantastic stock bumper is actually not super fantastic. It looks dull and boring and really only suited to small touches before it wraps in on itself.  Now we at Offroad Animal know there are lots of options for the rear of your JK but this one is just cool.  It has great features and looks ace.  Try it, you'll like it.
