Kyosho Mini-Z Overland Rear Motor Heat Sink by GPM MOL031  [MOL031]

Rear Motor Heat Sink for Mini-Z Overland

This alloy rear heat sink is an RC-scale accessory designed for the Kyosho Mini-Z Overland platform, intended to manage motor temperature in high-rev or sustained-use conditions. The part is presented as a single unit and focuses on passive cooling by increasing surface area and using an alloy material to move heat away from the motor casing.

Fitment is specific to the Mini-Z Overland chassis family; verify visual match with your rear motor mount and motor can before installation. Installation typically involves removing the motor mount cover or existing shroud and fitting the heat sink against the motor casing so it makes stable contact without obstructing gear mesh or suspension components. Use appropriate fasteners from your kit and check clearance for wiring and gearbox movement after fitting.

In tuning contexts, this heat sink serves as a thermal management option rather than a power upgrade. It helps stabilise motor temperature during repeated short runs or practice laps on tight tracks, which can improve consistent performance and reduce thermal-related throttle cut or drag in sensitive electronics setups.
