KYOSHO Mini-Z Overland Rear Gear Arm MOL013R by GPM  [MOL013R]

Rear gear arm overview

This aluminum rear gear box arm is an aftermarket replacement built for KYOSHO Mini-Z Overland vehicles and mounts at the original motor location. It is designed as an RC-scale upgrade to help restore or increase rear gearbox support when the stock motor mount layout is retained.

The item comes as 1pcs and is manufactured from aluminum alloy to provide better wear resistance than standard plastic arms, while keeping mass appropriate for Mini-Z handling. Fitment presumes the vehicle still uses the original motor mount and gearbox path.

Installation is manageable for hobbyists with Mini-Z experience: remove the stock rear arm, move across bearings or pins if necessary, and fasten the alloy arm to the gearbox and motor mount using the existing screws. After fitting, inspect gear mesh and suspension geometry to prevent binding or drivetrain wear.

Tuning notes: changing to a metal rear arm may alter flex and how impacts are felt through the chassis during cornering or rough terrain, so adjust rear toe and ride height as needed. This is marketed as a durable replacement for scale trail and mild off-road Mini-Z setups and not as a major speed upgrade.
