Here, you can purchase a NP205 Colossus assembled with gears, shafts, and new bearings and seals.
The NP205 transfer case has been the Colossus of the 4x4 world for half a century. It is still the best choice for a starting point to build your offroad machine around. Behemoth Drivetrain has designed some unique products to make it even better. The most notable product being the "Colossus Case" for NP205 gears.
In the stock NP205 housing the gears were originally in a "V" configuration. In the NP205 Colossus they have been configured in a straight line. Because of this change, the input centerline and front output centerline have been moved 5/16" farther apart than stock. This will make a big difference when clocking flat behind large automatic transmissions. The gears are the same distance from the adjoining gear as or originally designed.
Rear output, and rear of front output have symmetrical 8 bolt patterns. This means that all of the stock (and aftermarket) NP205 parts will bolt to the Colossus housing, and can be clocked to the optimum position. (Slight modification to 1 of the 8 bolt holes in your stock parts is required.
Complete with gears installed and all billet aluminum options, The 2 Speed NP205 Colossus weighs only 109 lbs..
