KIT CONVERT TH350

This Maximizer Conversion Kit allows you to convert your pre-1980 4WD with a 203/205 Transfer Case from a TH350 to a TH400 transmission. Kits include a plate, output shaft, gasket, seal, and rear case bearing. TCI offers many different types of conversion kits for GM vehicles to enable interchange of various styles of GM transmissions, which is particularly useful for heavy-load vehicles benefiting 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. Specifically, this kit requires shortening the Rear Driveshaft by 3.7" and lengthening the Front Driveshaft by 3.7".
