The USA Standard Gear ZMBK132DWS is a comprehensive manual transmission bearing and seal kit, designed to restore the smooth operation of your 5-speed gearbox. USA Standard Gear has over 50 years of experience providing OEM and aftermarket manual transmission components, ensuring quality and fitment. This kit includes essential components for a transmission rebuild, such as synchronizer rings vital for seamless gear changes and a 20.5mm double ball front counter shaft bearing. This bearing plays a key role in maintaining proper alignment and smooth running within the transmission. Notably, the 3rd-4th gear synchronizer rings in this kit feature 36 teeth, differentiating them from the 1st-2nd rings and the reverse synchronizer ring, a detail critical for a successful rebuild. The ZMBK132DWS is application-specific, engineered for an exact fitment on the 5-speed manual transmissions found in the 1990-1993 Mazda B2200 and the 1989-1991 Mazda RX-7. It is supplied as a complete kit, containing all the necessary parts to ensure you are not left searching for additional components during your project. This transmission bearing and seal kit is a testament to their dedication, offering reliability and performance for enthusiasts looking to maintain or upgrade their manual transmission.
