3Racing 3RAC-MHS004/LB Light Blue 540 Motor Fan and Heat Sink  [3RAC-MHS004/LB]

Active Cooling for 540 Class Motors

The 3Racing Motor Heat Sink with Fan 3RAC-MHS004/LB is made for 540 motors and delivers dependable heat control during intense sessions. The light blue aluminum housing increases surface area and promotes better thermal transfer so the motor runs cooler under load.

Cooling That Helps Performance

Controlling motor temperature reduces thermal sag and helps protect internal parts. The built-in fan forces airflow across the fins to lower operating temperature, which can preserve power output and extend service life. This setup works well with many standard 540 motor installations found in sprint buggies and short course trucks.

Easy Fit and Reliable Contact

Mounting is straightforward thanks to common 540 can dimensions and drilled mounting points. Once fitted, the heat sink makes solid contact with the motor can for efficient heat transfer and a secure installation for regular track use.
