Mini-Z AWD Alloy Front/Rear Gear Joint MZA041 for MR-03 Compatibility by GPM  [MZA041]

Mini-Z alloy joint summary

This front/rear gear differential joint is provided as an aftermarket alloy option for Kyosho Mini-Z AWD cars and carries the model number MZA041. It is intended to sit inside compatible Mini-Z AWD differential housings and engage the stock gear train without altering the original driveline layout.

Construction and purpose: the alloy body gives stable load-bearing surfaces at the gear interfaces, limiting flex under normal club and track loads. The part is offered as a drop-in replacement for compatible Mini-Z AWD differentials, aimed at users who service and tune their diffs regularly and want a metal alternative.

Fitment and setup advice: disassemble the differential case using standard Mini-Z service procedures to install the unit. Check gear mesh, adjust endplay, and lubricate with light grease or diff fluid suited to your setup. Spin the assembly by hand to ensure smooth operation before refitting to the chassis.
