3Racing 3RAC-MHS4/PU/V2 Purple High-Flow 540 Motor Cooling Kit  [3RAC-MHS4/PU/V2]

High Capacity Cooling for 540 Motors

Improve motor reliability with the 3Racing 3RAC-MHS4/PU/V2 cooling kit. Built for 540-class motors, this unit combines a high-output fan and an efficient heatsink to move heat away from the motor during intensive sessions. The purple finish gives a neat visual upgrade while helping keep temperatures in check.

Engineered Heat Control

The 3Racing cooling assembly uses a robust fin array and a focused fan to speed up heat transfer from the motor housing. That active airflow helps prevent power loss and extends motor life under repeated high-load runs.

Built to Last

Made from durable materials, this cooling system is designed to handle club racing and regular track use without degrading. Its solid construction keeps the fan and sink stable even on rougher surfaces.

Quick Fit Installation

Installation is straightforward, allowing hobbyists to upgrade cooling with minimal tools. The design supports most 540 motors, making it a practical addition to workshop spares.
