Re: Who here has installed an Atlas II in a TJ?
I have a couple buddies running them behind autos. The t-case is still in nearly the same place so the same things should apply. If you want to use the flattest of the four mouting positions a little massaging of the floorpan will be required. You will also want to put a little extra heat shielding on the floor in the area near the t-case (the thin self adhesive foil backed stuff works fine) as the Atlas has been known to cook carpet in some installations. One of my buddies is running a prototype case he got from AA about a year ago. It allows the Atlas to mount totally flat, it may be an available option by now.
The twin sticks that are listed for the TJ (not the generic sticks) work well with the factory console. Some have trimmed the cosole slightly for easier operation, but it is usually not required.
Finally, depending upon your gearing you may be happiest with the 3.8 Atlas. Some who spend the extra money for the 4.3 end up regreting it because it is geared "too low". I know that I would most likely choose the 3.8 if and when I go with an Atlas. I have 100:1 now with a stock geared 300, the 4.3 would be a waste for me as I would rarely use 1st-low ratio of 163:1, the 144:1 of the 3.8 may be more than I would really use regularly.
