BW4493 Transfer Case

The Zumbrota Drivetrain RTC4493G-1 is a professionally remanufactured BW4493 transfer case, built to exacting standards for the 2006-2008 GM Hummer H3 equipped with the 3.7L engine. This transfer case is designed for AWD operation and features a 2.64:1 low-range ratio, a 27-spline input, a 32-spline slip yoke style rear output shaft, and a circular front output yoke. Zumbrota Drivetrain's remanufacturing process involves thorough inspection of all cases and internal components for signs of wear, such as cracks, stripped threads, shaft straightness issues, gear wear, and chain stretch. A specialized hydro-blast rinse and blasting procedure is used on internal and external parts, followed by a proprietary shot-enticed deep cleaning. Each unit is rebuilt with the replacement of all bearings, seals, and viscous couplers (when applicable). To ensure optimal performance, all finished units undergo thorough spin testing for shiftability and noise. The transfer cases are then shipped in high-density plastic totes to prevent damage during transit, ensuring they arrive in excellent condition ready for installation. This remanufactured unit comes with a 2-year limited warranty. This BW4493 transfer case is specifically designed for the 2006-2008 GM Hummer H3 3.7L. It is important to confirm fitment with your vehicle's specifications.
