KYOSHO Mini-Z AWD Rear Gear Box Lower Tray by GPM MZA013N  [MZA013N]

Aluminium rear lower tray for Mini‑Z AWD

This aluminium rear gear box lower tray is a direct-fit replacement part produced by GPM for Mini‑Z AWD models. Machined from 6061‑T6 aluminium, the part focuses on improved rigidity and dimensional stability compared with typical molded plates, making it useful where a firmer mounting surface for the rear gearbox is desired.

The tray locates the gearbox in the same footprint as the original, so installation centers on careful alignment and reuse of the stock fixing points. Users should check the original mounting screws and torque settings to ensure no interference with adjacent components such as the motor, spur gear, and rear suspension pick-up points. This part is described in source notes as an upgraded version of MZA013B.

In a tuning context the lower tray serves as a chassis-level upgrade to reduce flex at the gearbox interface, which can stabilise gear mesh under load and provide a more consistent drivetrain feel during setup changes. It is an RC-scale accessory intended for Mini‑Z AWD vehicles and is not for full-size automotive use.

Choose this tray when you need a rigid, repeatable gearbox mounting surface on KYOSHO Mini‑Z AWD platforms; fitment checks and standard maintenance of fasteners are recommended during installation.
