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

Aluminum rear gearbox arm summary

This aluminum rear gear box arm is an aftermarket replacement made for KYOSHO Mini-Z Overland models and is intended to attach at the original motor position. As a scale trail accessory, it restores or improves rear gearbox support while keeping the stock motor mount layout intact.

The item is supplied as 1pcs and uses an aluminum alloy for greater wear resistance compared with the standard plastic arm, while maintaining a weight suitable for Mini-Z handling. Correct fitment assumes the vehicle retains the original motor mount and gearbox routing.

Installation is straightforward for hobbyists familiar with Mini-Z maintenance: remove the OEM rear arm, move over any bearings or pins if needed, then secure the alloy arm to the gearbox and motor mount using the existing hardware. Use the correct hex driver and check gear mesh and suspension geometry after fitting to avoid binding or premature drive wear.

Tuning notes: swapping to an alloy rear arm can alter flex and impact feedback when cornering or running over rough ground, 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 upgrade.
