Kyosho Mini-Z AWD Alloy Front/Rear Gear Differential Joint by GPM MZA041  [MZA041]

Alloy differential joint overview

This aftermarket front/rear gear differential joint is designed for Kyosho Mini-Z AWD platforms and produced by GPM under model MZA041. It is an RC-scale alloy replacement component intended to sit in the Mini-Z AWD differential housings and interface with the vehicle’s internal gear train without modifying stock driveline geometry.

Material and role: the part uses an alloy construction to provide stable contact surfaces where the gear halves and differential joint meet, reducing deformation under moderate loads typical of club-level track use. It is presented as a direct-fit replacement for compatible Mini-Z AWD differentials and is aimed at hobbyists who want a metal option for repeated tuning and service cycles.

Installation and tuning notes: installation follows the same access path as the factory differential, requiring removal of the differential case and standard Mini-Z hardware for disassembly. When tuning differential performance, confirm gear alignment and endplay, use appropriate light grease or diff fluid as required by your setup, and check for smooth rotation before reassembly to avoid premature wear on mating gears and bearings.
