These Atlas 4-speed transfer cases from Advance Adapters have essentially two parts. The first part is the reduction housing. This housing holds a 6-gear planetary assembly that has a low range of 2.72:1 and a high range of 1:1. They use a planetary assembly that was originally run in an NP241-HD transfer case. This assembly has been rated to withstand 5,555 ft.-lbs. of torque and up to 11,000 lbs. gross vehicle weight. The second part of the 4-speeds may look the same as the standard 2-speed Atlas, but it does have some differences. The main case of the 4-speeds 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 of this is put together, you get these new legendary Atlas transfer cases with the best combination of gear ratios (1:1, 2.0:1, 2.7:1, and 5.4:1) or (1.1, 2.7:1, 3.8:1, and 10.3:1).
