Description

The USA Standard Gear ZMM5R1-19A is a manual transmission 5th gear countershaft designed for M5R1 transmissions. This component is an updated replacement, featuring 30 synchro teeth, which differs from the 36 synchro teeth found on 1988-1992 models. This gear is specifically intended for use in manual M5R1 transmissions. It is a direct fit for several Ford Ranger and Mazda B-series truck models manufactured between 1992 and 2000. Applications include the Ford Ranger, Mazda B4000 (1994-2009), Mazda B3000 (1994-1996, 1998-2007), Mazda B2500 (1998-2001), and Mazda B2300 (1994-1997, 2001-2009). This part is a replacement for the 5th gear countershaft, providing a solution for worn or damaged components within the manual transmission. It is manufactured by USA Standard Gear, known for its range of transmission, differential, and general replacement parts.
