That is the new smittybilt bumper. It is still in r&d with no eta on completion.
I work for 4wheelparts, we are owned by the same company that owns Smittybilt. They do this all the time where they pre-release product, and then run into issues with manufacturing. I will honestly be surprised to see that bumper by spring 2014 if at all.
I was thinking of getting the Rigidco sliders, but didn't know he was making rear bumpers too. He really needs to refresh his website!
I'm digging this bumper!

But I would want it with a drivers side swing and tire mount. I'm going to have to give him a call in the next couple of weeks and see what he can do.
Thanks for the heads up!
