Buy a ProRock44.
Do an ARB and 35 splines in your rear.
Run one step shorter gears than you would if it were a a rubi (to help make up for the transfer case).
Either buy a broken rubi sway bar and the no limits or get some quick discos.
That route will net you better axles than the rubi for less than the price difference and you won't pay interest on the parts. As long as you aren't running over 37s or blasting through the dessert this setup will be just fine for you.
If you ARE running over 37s or planning on blasting through the dessert then everything that makes a rubi a rubi, other than the transfer case and e-discos, will be swapped for aftermarket stuff anyway. At that point you will be paying the roughly $10k difference for a rubi PLUS interest for a transfer case and e-discos that will eventually fail anyway.
I know people think the Rubicon package is the be all end all and I would agree if you are leaving it stock. BUT if you are modifying your Jeep, it's much smarter financially to start with the sport.
***If not having leather interior and an upgraded but still shitty sound system was a deal breaker, you would have gotten a rubi from the get go, so those things were not taken into account.***
