The Atlas II is designed and manufactured by Advance Adapters for the serious off-road enthusiast. The Atlas II is an all gear driven transfer case available with 3.8:1 or 4.3:1 low range for rock crawling and is still 1:1 for highway driving.   When Advance Adapters designed the Atlas II they went for the strength of the NP 205 and the size of the Dana 300 and came up with something in-between.  The 32 spline output shafts make it strong like the NP 205 but it is only 2″ longer than the Dana 300.  They also designed it to fit left or right hand off-sets for many applications.

The Dana 300 transfer case was used in the late Jeep CJs (1980-1986 ). It is a gear driven unit with stock 2.64 to 1 low range. We offer them completely rebuilt ready to install with stock shifter. Our rebuilds include all new bearings, seals, gaskets and welded paddles for added lubrication when in tow. They are also available with 4to1 low range and twin stick shifters. You also have a choice of strap type, u-bolt type or 1350 series yokes.

The NP 205 transfer case was in GM, Ford and Dodge trucks form ½ ton to 1 ton.  It was used in the late 1960’s and early 1970’s in the ½ tons but eventually fazed out in the later years and used only in the 1 tons.  The NP 205 has become very much in demand because of its strength and dependability.  Since it was so widely used it can easily be adapted to replace a lot of the smaller and weaker chain drive transfer cases.
