The Advance Adapters Atlas 4 speed has essentially two parts. The first is the reduction housing This housing holds a 6 gear planetary assembly that has a low range of 2.72:1 and a 1:1 in high range. We use a planetary assembly that was originally run in a NP241-HD transfer case. This assembly has been rated to withstand 5,555 ft/lb of torque and up to 11,000 lbs gross vehicle weight.

The second part of the 4 speed may look the same as the standard 2 speed Atlas, but it does have some differences. The main case of the 4 speed is the same raw casting, but has some machining variations to make it into a 4 speed. The main case functions independently from the front reduction housing and retains all of the normal Atlas features.

When all this is put together, you get a new legendary Atlas transfer case with the best combination of gear ratios ( 1:1, 2.0:1, 2.7:1 & 5.4:1 ) or ( 1.1, 2.7:1, 3.8:1 & 10.3:1 ).
