Maintain Consistent 540 Motor Duty

The 3Racing 3RAC-MHS004/TI combines a slim titanium heat sink with an active fan to control motor temperature during extended use. Its corrosion-resistant finish and compact form are suited to 540 motors that face sustained loads.

Efficient Airflow and Durable Material

The fan forces air through the fin stack to lower thermal peaks while the titanium body gives strong heat conduction and long-term durability. This reduces thermal strain on internal components during hard runs.

Quick Upgrade Path for Most 540s

Installation is designed to be quick for home tuners and racers, fitting the common 540 form factor. It is a practical cooling upgrade across a wide range of on-road and club-level vehicles.

Can I fit this to a sealed can 540?

Many sealed can 540s accept external heat sinks if the dimensions match. Verify shaft clearance and endbell shape before fitting the 3Racing heat sink.

Does the fan require a separate power source?

The fan is usually self-contained and draws low current from its wiring. Check the product notes for wiring options and any connector needs for installation.

Will the titanium sink change motor balance?

The added mass is small and typically does not affect rotor balance, but it is good practice to spin the motor and check for vibration after installation.
