Description

The USA Standard Gear ZMM5R2-2.5 is a replacement 3rd and 4th gear synchro assembly specifically engineered for the M5R2 manual transmission. This component is crucial for smooth gear engagement in the specified model years. Designed for 1988 through 1998 Ford F-150 and Mazda vehicles equipped with the M5R2 transmission, this synchro assembly ensures proper function of third and fourth gears. It features a 0.32-inch wide fork slot for precise engagement. Please note that keys and springs are sold separately and are not included with this synchro assembly. This part is a direct replacement for worn or damaged synchro assemblies, helping to restore proper shifting performance and prevent grinding or difficult gear changes. Ensure compatibility with your specific vehicle's transmission model and year range before purchase.
