KYOSHO Mini-Z Overland rear gear box arm mount by GPM MOL013R  [MOL013R]

Alloy rear gear box arm mount overview

This alloy rear gear box arm mount is an aftermarket replacement designed for KYOSHO Mini-Z Overland models, intended to mount to the original motor position. Built as an RC-scale accessory, the part focuses on restoring or improving rear gearbox support when using the stock motor mount layout.

The part is supplied as 1pcs and is made from aluminum alloy to resist wear compared with standard plastic arms, while keeping weight appropriate for Mini-Z handling. Fitment assumes the vehicle retains the original motor mount and associated gearbox routing.

Installation is straightforward for hobbyists familiar with Mini-Z maintenance: remove the stock rear arm, transfer any bearings or pins if required, and secure the alloy arm to the gearbox and motor mount with the existing hardware. Use the correct hex driver and verify gear mesh and suspension geometry after fitting to avoid binding or drivetrain wear.

Tuning notes: replacing the rear arm can change flex and impact feedback during cornering and over rough surfaces, so recheck rear toe and ride height after installation. This component is intended as a durable replacement for scale trail and mild off-road Mini-Z setups rather than a major performance modifier.
