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

Replacement alloy joint overview

This front/rear gear differential joint is an aftermarket alloy alternative for Kyosho Mini-Z AWD models and is identified by model MZA041. It is designed to sit inside Mini-Z AWD differential housings and engage the vehicle's internal gear train without altering factory driveline geometry.

Function and build: alloy construction gives stronger contact surfaces where gear halves meet the joint, helping to reduce deformation under routine club and track loads. The item is supplied as a direct-fit option for compatible Mini-Z AWD diffs and is aimed at operators who service and tune their models frequently.

Installation advice: access the diff via the standard case removal procedure and use regular Mini-Z service tools for disassembly. When rebuilding, check gear alignment and endplay, use a light grease or diff fluid that suits your handling preference, and confirm smooth rotation before final assembly to protect gears and bearings from premature wear.
