TRAXXAS TRX4 Trail Crawler 35mm Aluminum Motor Heat Sink with Cooling Fan by GPM TRX4018FAN  [TRX4018FAN]

35mm Aluminum Motor Heat Sink with Fan

This GPM TRX4018FAN kit is an RC-scale motor cooling accessory designed for TRAXXAS TRX4 Trail Crawler use, providing a combined heatsink and top-mounted fan to reduce motor temperature during prolonged low-speed crawling and technical trail runs. The assembly uses a 35mm sink profile and includes the adapter and fasteners needed to fit standard 540-size motors.

Compatibility: the unit is intended for 540 motors only, using the supplied plug adapter and screws for mechanical mounting. Installation requires removing the motor endbell as needed, fitting the heatsink over the motor can, securing the fan lid and wiring the fan to an appropriate 5–12V source on your model's electrical system; ensure the fan supply matches your ESC or auxiliary power setup.

Tuning role: this part helps manage motor thermal load rather than changing gearing or power delivery; fitment can reduce temperature rise under sustained low-speed torque, improving predictable performance during technical crawling sessions without altering motor output characteristics.
