USA Standard Gear ZMM5R1-19A Manual Transmission MR5 5th Gear Countershaft Updated 1992-2000

The USA Standard Gear ZMM5R1-19A is an updated 5th gear countershaft designed specifically for M5R1/M5OD 5-speed manual transmissions found in 1992-2000 Ford Ranger, Ford Explorer, and Mazda light trucks. This is the updated version that replaces the original design, providing improved durability and performance for manual transmission rebuilds.

Key Features:

• 30 synchro teeth design - Updated specification for improved engagement
• Direct replacement for M5R1/M5OD transmission countershaft 5th gear
• Compatible with 30-tooth 5th synchro and 1-piece 2nd synchro assemblies
• Precision-manufactured to OEM specifications for reliable transmission performance
• Essential component for complete manual transmission rebuilds and repairs

Application Note: This updated version features 30 synchro teeth and is designed for 1992-2000 model year applications. Earlier 1988-1992 models used a different design with 36 synchro teeth. To verify compatibility, count the synchro teeth on the ring rather than the gear itself - 1992-2000 models have 27 teeth on the synchro ring.
