Description

This unit is designed as a direct replacement, featuring a 29 spline input shaft and coming complete with a new shift motor. This transfer case is engineered for specific General Motors trucks, including the Chevrolet Silverado 2500 HD and 3500 HD, and GMC Sierra 2500 HD and 3500 HD from the 2011 to 2015 model years. It is compatible with models equipped with the Allison Transmission and features an electric shift mechanism with Option Code NQF. The unit has an oval mounting pattern and a screw-in speed sensor. Zumbrota Drivetrain puts all units through a proprietary cleaning method and a complete inspection process, including component replacement and quality control, before they are signed off by their rebuild team. This ensures the transfer case arrives looking and functioning like new. Additional details such as tag numbers (23188334, 24244450, etc.), Hollander number (412-754), and other numbers (UMT141-9) are available for cross-referencing.
