Mini-Z Overland Alloy Rear Heat Sink MOL031 for rear motor by GPM  [MOL031]

Alloy rear heat sink for Mini-Z Overland

This rear heat sink is made from alloy and tailored for the Kyosho Mini-Z Overland rear motor arrangement to help manage temperatures during sustained use. It relies on added surface area to disperse heat from the motor can without introducing fans or extra electronics.

Fitment is specific to Mini-Z Overland chassis versions; check the rear motor mount geometry and motor can clearance before attempting fit. Installation usually involves removing the mount cover or existing shroud and seating the sink snugly against the motor can, ensuring it does not interfere with the gear train or suspension travel. Use appropriate hardware from your kit and recheck wiring routing and gearbox movement after fitting.

For tuning, this part is a thermal support item rather than a performance upgrade. By reducing temperature variation over runs it can help maintain consistent power delivery and limit temperature-related protective behaviour in speed controllers or motors.
