Description

The USA Standard Gear ZMNV23678 is a direct replacement 1st and 2nd gear synchro assembly designed for the NV4500 manual transmission. This synchro assembly is specifically for the 1st and 2nd gears within the NV4500 transmission. Please note that this part does not include the necessary keys or springs for installation; these components must be sourced separately. Applications include a wide range of Dodge, Chevrolet, and GMC trucks from the early 1990s through the mid-2000s, including specific models like the Dodge Ram 2500/3500 (1994-2005) and Chevrolet Silverado 2500 HD (2001-2006).
