   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. 

   You can save a little money with the Colossus by using your stock NP205 rear output housing, and bearing retainers with our base kit. 

   Or, you can "go for the Gusto" and get all the replacement billet 6061 retainers to match the housing.
