Tamiya M03M Motor Heatsink by 3Racing M03M-21/SI - Race Ready Cooler  [M03M-21/SI]

Targeted cooling for Tamiya M03M

The Tamiya M03M Motor Heatsink by 3Racing, model number M03M-21/SI, is designed to improve heat management on the Tamiya M03M chassis. It helps stabilise motor temperatures during extended track use so performance stays consistent through long runs.

Improved heat dissipation

Built from quality materials, this heatsink increases the motor's surface area to shed heat more effectively. The result is lower operating temperatures under sustained load, which supports longer runtimes and less thermal stress on the motor.

Fitment and simple install

Engineered for the Tamiya M03M, the heatsink fits without alterations and installs with common RC tools. The design integrates neatly with stock components for a clean look while improving cooling performance.
