I just got finished rigging up an ARB twin Compressor in my JK. It ended up taking a lot longer than I thought it would, but I am really happy with the finished result. That little thing pumps some air! I hooked it up to a one gallon air tank to make it easier to run air tools. I also hooked up a couple quick connects to allow for easy access.
I had some extra brackets cut when I had mine made, so if anyone is interested in a bracket let me know.
