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

Aluminium rear gearbox arm details

This aluminium rear gear box arm is an aftermarket replacement crafted for KYOSHO Mini-Z Overland cars and is meant to bolt into the original motor position. It is presented as a scale trail component focused on restoring or improving rear gearbox support while using the stock motor mount arrangement.

The unit ships as 1pcs and is produced from aluminium alloy to resist wear better than standard plastic arms, while keeping the weight appropriate for Mini-Z dynamics. Fitment requires the vehicle to retain the original motor mount and the same gearbox routing.

Fitting is straightforward for those comfortable with Mini-Z service: remove the factory rear arm, transfer bearings or pins if needed, then attach the alloy arm to the gearbox and motor mount with the existing hardware. Confirm gear mesh and suspension geometry after installation to prevent binding or unnecessary drivetrain wear.

Tuning advice: replacing the rear arm can affect chassis flex and impact response on rough terrain, so check rear toe and ride height after fitting. The part is intended as a robust replacement for scale trail and light off-road Mini-Z use rather than a radical performance part.
