Description

The Zumbrota Drivetrain RTC1370G-4 is a remanufactured transfer case built to replace BW1370 and BW4401 units. This specific model is designed for the 1994 GM K3500. It features a 4-inch bell front yoke and a S/Y rear output yoke, along with a 3-prong switch for the shift lever position. Zumbrota transfer cases undergo a rigorous remanufacturing process. This includes a proprietary cleaning method, component replacement, and a thorough inspection. Each unit is signed off by a rebuild team member to ensure it meets high standards of precision and reliability. The aim is to provide a unit that looks and performs like new, offering peace of mind for resale or installation. When purchasing this transfer case, a core return or core charge is required. The refundable core charge is $600. You can opt to send your core in first before shipment or pay the core charge to expedite shipping. Vehicle VIN may be requested to help guarantee fitment.
