The NP205 is a cast iron, gear drive transfer case with a 1:1 high range and a 1.96:1 low range. It is considered by many to be the strongest transfer case ever factory installed in one ton and smaller 4x4's. The basic design of the 205 remained unchanged throughout its production history with the exception of synchronized front output shaft briefly used by GM in the early 1980's. The synchronized version was intended to provide shift-on-the-fly 4x4 capability with automatic locking hubs. Unfortunately, it didn't really work out as intended, and GM canceled the production contract almost immediately, but they were obligated to take enough units to pay for New Process's tooling costs. Most synchronized 205's are in the 1982 to 1983 model year GM 1 tons, however, GM still had enough transfer cases on hand to apparently offer it as an option on 1-ton trucks for several more years. During the 1990's a good number of Chevy and GMC C3500 4x2 1 Ton trucks were converted to 4x4 for fleet use until the supply of brand new NP205 transfer cases dried up in the mid-1990's. The NP205 can also be found in some types of specialized construction and off road equipment.
