Description

The USA Standard Gear ZMBK133AWS is a comprehensive manual transmission bearing and seal overhaul kit specifically engineered for 1986 and newer Hardbody 4-cylinder vehicles equipped with 2WD and synchros. Key components include a 61mm Outer Diameter (O.D.) front countershaft bearing and a 26mm O.D. input pocket bearing, ensuring precise fitment and function. The kit also features multi-piece 2nd gear synchronizer rings and 1st-2nd gear synchronizer rings that are larger than the 3rd-4th gear rings, contributing to improved gear engagement and durability. This USA Standard Manual Transmission Bearing Kit is compatible with a range of Nissan vehicles from 1984 through 1993, including the 200SX (1984-1988), 300ZX (1984-1987), D21 (1986-1993), Pathfinder (1987), and Van (1987-1988). It is crucial to verify fitment with your specific vehicle's year, make, model, and transmission configuration.
