MR5 5th Gear Countershaft Update Kit

The ZMM5R1-19A from Zumbrota Drivetrain is a USA Standard Gear countershaft update specifically for the MR5 manual transmission, suitable for 1992-2000 Ford Ranger and Mazda models. This kit addresses the 5th gear countershaft update and is distinguished by its 30 synchro teeth count. It is crucial to note the distinction in synchro teeth count for different model years. Earlier models, specifically 1988-1992, featured 36 synchro teeth and this particular update kit (ZMM5R1-19A) is not compatible with those earlier transmissions. The product details clarify that the synchro teeth should be counted on the ring, not the gear itself. The 1992-2000 models utilize 27 synchro teeth on the gear, but this kit provides a 30 synchro tooth count for the countershaft update. This part is listed under the Differentials and Rear-End Components subcategory and is designed as a direct replacement or upgrade component for the specified manual transmission. The product is in stock and available for immediate dispatch.
