The TRX4018FAN is an RC motor cooling kit aimed at TRAXXAS TRX4 Trail Crawler style vehicles, combining a compact 35mm aluminium sink with a top fan to help control motor temperatures during technical, low-speed crawling. The kit ships with the heat sink, fan lid, plug adapter and mounting hardware for standard 540-size motors.
Compatibility: built for 540 motors only, it uses the supplied plug adapter and steel screws for mounting. Fitting may require removal of the motor endbell, sliding the heatsink over the motor can, securing the fan lid and wiring the fan to an appropriate 5-12V point on your model; confirm compatibility with your ESC or accessory power source.
Thermal benefits: this aftermarket component reduces sustained temperature rise under high torque crawling and assists in preserving consistent motor behaviour without changing motor gearing or electrical output.
