Parts for GM Rockwell T221 Transfer case in Chevy, GMC Trucks

The Timken designed, Rockwell T221 Transfer Case was used in some 4x4 conversion applications prior to 1960. General Motors selected the T221 as the production transfer case for the new 1960, Chevy and GMC factory option 4x4 trucks. The T221 is a  4 shaft, "Clover Leaf" design transfer case. The T221 design is reasonably strong, especially considering the low-power engines it was coupled to, but by 1960, the T221 design was obsolescent for the American market due in part to the advent of the Interstate highway system and the increasing long-distance recreational use of pickup trucks. The T221 typically runs hotter and is generally noisier than contemporary Dana and New Process transfer cases used in Dodge, Ford, IHC, and Jeep full size trucks. The T221 was replaced by the New Process NP205 for the 1969 Blazer and all 1970 models.
