GM used the New Process NP208C chain drive part time transfer case for Blazers, Jimmys, Suburbans,1/2 ton and 3/4 ton "square" body style pickups from 1981 through 1987. For the 1988 model year, the NP208C was only installed in Blazers, Jimmys, and Suburbans. The NP208C is a light weight aluminum case transfer case is synchronized between 4x2 and 4x4 modes for use with automatic locking hubs. NP208C Transfer Cases have a 1:1 high range and 2.61:1 planetary gear low range. The NP208C generally provides reasonable service for the average user, but it was never considered to be a particularly strong or durable unit in full size trucks used for tough vocational or off road applications. The NP208C was replaced in Blazers, Jimmys, and Suburbans by the New Process NP241C transfer case effective with the 1989 model year.
