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

Precision aluminium lower gearbox 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 component is engineered to increase rigidity and dimensional stability versus molded plates, providing a firm and repeatable mounting surface for the rear gearbox assembly.

The tray preserves the original gearbox footprint so installation is performed using the stock fixing points and accurate alignment. Check fastener condition and torque during installation to prevent interference with adjacent components including the motor, spur gear, and rear suspension pick-ups. The item is referenced as an improved iteration of MZA013B in the product notes.

In application this lower tray functions as a chassis-level upgrade to reduce flex where the gearbox mounts to the chassis, which can stabilise gear mesh under dynamic load and deliver a more consistent drivetrain response during tuning. This product is intended strictly for Mini-Z AWD model use and not for full-size vehicles.

Specified for builders seeking a robust and repeatable gearbox mounting platform on KYOSHO Mini-Z AWD chassis; confirm fitment and perform routine fastener checks when fitting.
