GPM MOL013R KYOSHO Mini-Z Overland Rear Gearbox Arm  [MOL013R]

Aluminium rear gear arm overview

This aluminium rear gear box arm is an aftermarket replacement for KYOSHO Mini-Z Overland models and is intended to attach at the original motor position. As a scale trail component it focuses on restoring or improving rear gearbox support while keeping the stock motor mount configuration.

The product is supplied as 1pcs and is made from aluminium alloy to resist wear better than typical plastic arms, while keeping weight suited to Mini-Z handling. Proper fitment assumes the car retains the original motor mount and associated gearbox routing.

Installation is suitable for hobbyists with Mini-Z experience: remove the factory rear arm, transfer bearings or pins if required, then secure the alloy arm to the gearbox and motor mount using the existing hardware. Check gear mesh and suspension geometry after fitting to prevent binding or undue drivetrain wear.

Tuning advice: fitting an aluminium rear arm can change chassis flex and impact feedback on rough surfaces, so review rear toe and ride height after installation. The component is aimed at providing a durable replacement for scale trail and light off-road Mini-Z setups rather than acting as a major performance modifier.
