ARRMA ARA-2092 Motor Heatsink V2 3660 3668

This ARRMA V2 motor heatsink fits 3660 and 3668 size brushless motors, clamping around the motor can to dramatically increase the surface area available for shedding heat. Brushless motors lose power as they heat up and lose lifespan when they overheat — a heatsink is the simplest passive protection you can bolt on.

The finned aluminum design draws heat out of the motor can and gives moving air far more surface to carry it away. It works on its own during normal driving and pairs naturally with the 35mm motor fan set (ARA-2091) for maximum cooling in the hardest conditions — summer bashing, sustained full-throttle running, and higher-cell setups.

The V2 designation marks this as the current revision, and the 3660/3668 sizing covers the motor cans used across several ARRMA 3S-class vehicles including the Granite 223S.

Confirm your motor's can size before ordering. The package includes one V2 motor heatsink for 3660 and 3668 motors.
