The Advance Adapters Atlas gear-driven transfer cases are the ultimate in gearing and strength. These units are the solution for combining both on and off-road performance. From its inception in 1996, we have numerous inquires to fit the Atlas into a wide spectrum of vehicles. These units can be found in daily driven vehicles, all the way up to the extreme rock crawling vehicles. When you want or need peace of mind on the trail, in the rocks, on the sand, or in the mud, the Atlas is the transfer case for you.

-Due to the additional length of the 4-speed ve other transfercases, moving / modifying your transmission crossmember may be recommended. Contact for more info.

Gear Ratio Notes:
The Most common ratios are 3.8, 4.3. The second ratios is always a 2.7. Contact me if you need further guidance on selecting your gear ratio. 

Series Notes:
The Pro series has stronger and cooler running internals and is recommened for vehicles running over 600+ HP, and 42"+ Tires. For all others, the Trail series is recommended. 

Speedometer Notes:
 2005+ Nissans (N50 & D40) do not need a speedometer. The speed is read off of the ABS sensors. Select None. 

 1990 - 2004 Nissans Need the mechanical speedometer option. Adapting the mechanical speedometer in the atlas to your vehicle is up to you. Some early 90's vehicles will simply need a speedo cable adapter while later models are electronic and will need to be adapted as such. Contact me for more info. 

Yoke Notes:
Your Yoke Selection is dependant on the driveshafts that you intend to run. Driveshaft Modifications will be required for installation of an Atlas Transfercase.
