Description

The USA Standard Gear ZMBK308CWS manual transmission bearing kit is engineered for NV4500 transmissions specifically for 1999 and newer GM vehicles. This comprehensive kit provides the necessary components for a transmission rebuild, ensuring smooth operation and longevity. Constructed with a durable cast iron case and an aluminum top cover, this bearing kit is built to withstand demanding driving conditions. It features an external slave cylinder design for efficient clutch actuation. The kit includes essential synchronizer rings to facilitate proper gear engagement, though it is important to note that a reverse synchronizer ring is not included. This bearing kit is compatible with NV4500 transmissions found in 1999 and newer GM applications. Specific vehicle fitment may include models such as Chevrolet C2500, C3500, K2500, K3500, and P3500 from the 1999 and 2000 model years, among others that utilize the NV4500 transmission.
