Description

The Zumbrota Drivetrain RTC1370G-2 is a remanufactured transfer case designed specifically for 1989-1993 GM K3500 models. This unit ensures a quality build and reliable performance, having undergone a comprehensive remanufacturing process by Zumbrota. The transfer case features a 32-input gear spline and a chain-driven transfer case type. It also includes a 4-inch bell style front output for specific fitment. Zumbrota remanufacturing processes include a proprietary cleaning method, rigorous inspection, replacement of all worn components such as bearings and seals, and a final quality control sign-off. This ensures the transfer case arrives looking and performing like new, built to the highest standards of precision and reliability. Please note that this transfer case does not come with a slip yoke included and may require a core return or core charge as part of the purchase process. The "Short Description" indicates this unit is for the BW1370 & BW4401 Transfer Case. To guarantee fitment, providing your Vehicle VIN is recommended.
