Description

The ZMBK104WS is a comprehensive manual transmission bearing and seal overhaul kit from Zumbrota Drivetrain, specifically engineered for 1981-1986 Nissan Pickup models equipped with a 5-speed transmission. This kit ensures a complete rebuild with all necessary components included, such as synchronizer rings and a brass 5th synchro ring. It features a 60mm Outer Diameter (O.D.) front countershaft bearing for precise fitment and reliable operation. By replacing worn bearings and seals, you can prevent further damage and ensure optimal performance for years to come. The inclusion of synchronizer rings is crucial for proper gear engagement and shifting quality. Ensure your vehicle is a 1981-1986 Nissan Pickup with a 5-speed manual transmission for correct fitment. Always consult a professional if you are unsure about installation procedures.
