Kyosho Mini-Z Overland Rear Cooling Fin MOL031 by GPM  [MOL031]

Rear cooling fin for Mini-Z Overland motors

This alloy rear cooling fin is designed to fit the Kyosho Mini-Z Overland motor position and provide passive temperature control for motors run at high RPM or over multiple short outings. The alloy body increases surface area to move heat away from the motor can.

Fitment targets the Mini-Z Overland family; confirm the heat sink lines up with your rear motor mount and motor can before fitting. Fitting usually requires removing the existing cover or shroud and clamping the sink to the motor can without letting it contact gears or suspension parts. Use correct screws from your kit and verify wire and gearbox clearances once installed.

As an aftermarket thermal accessory, it reduces temperature swings rather than boosting power. Keeping motor temperatures steadier across heats can minimise thermal cutbacks and help maintain repeatable throttle response in sensitive setups.
