Price: $2,000.00
Pros: The Atlas II is super tough, and very reliable. By the way the drive shafts attach, you have the option of disconnecting a drive shaft and still retain mobility should anything go wrong down stream of the t-case.
Cons: As a shift-on-the-fly t-case you must be moving to shift. This can take some practice in certain terrain.
Recommended? Yes

Comments: I am thoroughly satisfied with my AtlasII! It's bomb proof. The Staff at Advanced Adapters are very helpful as well. The shifting options ensure that the wheel that needs the power gets it.

Price: $2,100.00
Pros: It's an Atlas what's to say ;-) I got it free from the '09 Jeep Safari but the site wouldn't let me put in 0.00
Cons: Tight fit with a 33 engineering skid even with a bit of work with the BFH on the tub. Not really a con but the only one I could think of.
Recommended? Yes

Comments: Well worth the work to install, and the cost of 2 new driveshafts and the cable shifters. The ability to have 2lo and front wheel only is a big plus in the areas I wheel. Front only allows re-positioning on waterfalls which came in handy a couple of times in the first few outings, 2lo is great on slickrock.

Pros: Bomb proof. Great quality. Built to my spec's. It's an Atlas!
Cons: Took a looooong time to receive, but I guess that's to be expected from a build-to-order company that puts so much emphasis on quality.
Recommended? Yes

Comments: Advanced Adapter's not only make THE best transfer cases in the world, they are also a class act. Two weeks after I ordered my Atlas II, Advanced had a 10% off sale. I called to ask if I could get in on the reduced price. No problem. They credited me back $23 on the spot.

Pros: HD output front and rear 32 spline,
Cons: size and retrofit
Recommended? Yes

Comments: Fairly easy to install if you have 1"mml and 1" bl in a yj. best to have body off during a rebuild if you can do it. Requires multiple test fits, and some pan mods. I had to cut my shifter tunnel and reweld new plates.

Great case.

Comments: The install was a bit more complicated than I originally though, but well worth it. The lower gears are great for crawlin' and the added manueverability with the twin sticks is great. As an added plus... front digs are just cool.

Price: $2,421.23
Pros: All gear driven goodness, 4.3:1 low range, Independent Axle Control
Cons: If anything the weight and size
Recommended? Yes

Comments: Just installed the Atlas but from the install everything went well. The key I think is on your end getting the shifters setup correctly. I am fully confident that AA took care of their end in terms of putting together a great transfer case....hopefully the last one I will ever need.

EDIT: Have been using it and WOW the 4.3:1 ratio is awesome and it drives GREAT!! IMO it was worth the money.
