I have an 06 Rubicon LJ setup the same.... 37's, 5.13's, ARB front and rear (separate switches) with Rubicrawler. I also put seat heaters in on my factory seats, each with its own control (love them) Thing is a beast in the rocks and snow with the Rubicrawler. Being able to split gears no matter if in 2wd, 4WH or 4WL is amazing and completely changes wheeling. You will love it like this!!
