This Maximizer Conversion Kit allows you to convert your pre-1980 4WD with 203/205 Transfer Case from TH350 to TH400. Kits include plate, output shaft, gasket, seal and rear case bearing.
TCI offers many different types of conversion kits to owners of GM vehicles that enable interchange of various styles of GM transmissions. This is particularly useful for heavy load vehicles that may benefit from a heavier-duty transmission for dependability. All kits provide the necessary adapter plate, output shaft and hardware required for installation. Kits will require some degree of driveline modifications.
