I just happen to have a sweet black 2011 6 speed sport 4door. Manual locks/windows already on 4" lift 37s. 104k miles. Let me get that LJ and a few bucks lol... but really

 

My Dreams that have not yet existed

 

You might luck out and get a Rubi TC as a swap for a person that wants to do the V8 conversion. I swapped mine straight over to my son for no cash difference but have a friend who got the same deal from another guy who did a 6.2 conversion. Son's Sport is better now with 3.73 gears and 4:1 TC. Doesn't have to take a run at things as much, can crawl better.
Robbie @ Motech in Vegas has quite a few Rubi TC's but not sure how much he needs for them though.

 

I'd say get the Sport, add one of the G2 dual-rate sway bars if you need that sorta action, and add the T-case of your choosing with the money saved on the Sport instead of the Rubi! But I'd only put it up on a 2" kit--even on 'tons.
