There are lots of aftermarket bumpers out there for the JK - both front and rear. You should have no problem finding what you're looking for. Look at this thread on an American JK forum to see a lot of options. Just be aware that since the JK's are still relatively new, their aftermarket stuff is a more expensive than TJ aftermarket stuff. Also, most of these "off the shelf" bumpers are made in the US, and shipping, customs fees, brokerage, and more shipping can really add up.

Option #3 (what I feel is DEFINITELY the best value for the money) is having someone local build you what you're looking for. You could contact Pookapotamus on this board ( he's fabbing TJ front bumpers at the moment, but I'd wager that he'd be willing to take on a project) or Lemon-Aid Jay at Chanda precision might be interested. I'm 100% certain that you'd be happy with a bumper from either one of those guys. Jay made my bumper almost two years ago and it's going strong...and I've tested it once...or twice...
