Kyosho Mini-Z AWD Second-stage Copper Servo Gear MZA622T by GPM  [MZA622T]

Copper second-stage servo gear for Mini-Z AWD

This copper second servo gear is a direct replacement option for Kyosho Mini-Z AWD platforms and carries the part number MZA622T. Placed within the servo reduction train, the copper gear meshes with adjacent pinions and the spur to provide metal durability where plastic parts commonly run.

Guidance for fitting: remove the servo and examine the gear stack before installation, check spline engagement, set mesh correctly with the mating pinion, and verify endplay after reassembly. Because copper fits differently than plastic, confirm adequate clearance under light load and manually rotate the drivetrain to ensure even engagement.

Performance note: this copper second gear is suited to setups that demand improved wear resistance and stable tooth contact, especially in high-use or closely geared Mini-Z AWD cars. Maintain with light micro-gear grease and routine servo inspections to keep the gear functioning well.
