Description

The USA Standard Gear ZMBK133BWS is a comprehensive manual transmission bearing and seal overhaul kit specifically engineered for 1987-1989 Nissan 300ZX models equipped with synchros. This kit contains all the necessary components to effectively rebuild the bearings within your transmission. Key included parts feature a 61mm Outer Diameter (O.D.) front countershaft bearing and a 26mm O.D. input pocket bearing, ensuring precise fitment for the intended application. The kit also provides multiple synchronizer rings, including a multi-piece 2nd gear synchro ring, and highlights that the 1st-2nd gear synchronizer rings are dimensionally larger than the 3rd-4th gear rings.
