Tamiya F103 Aluminum Motor Heatsink by 3Racing F103GT-09A/LB Race Cooler  [F103GT-09A/LB]

Upgrade cooling for Tamiya F103 series

The Tamiya F103 family has long been favoured in club racing and weekend meetups for its balance of handling and tuneability. The 3Racing F103GT-09A/LB Aluminum Motor Heatsink is a straightforward upgrade to help manage motor temperatures. Made from quality aluminum with a light blue finish, the heatsink increases thermal recovery so motors stay cooler during long runs and hard sessions.

Benefits for on road performance

Designed to fit the Tamiya F103, F103GT, and F103RM chassis, this heatsink keeps added mass low while improving thermal transfer. The fin profile raises surface area to promote airflow and speed heat movement away from the motor casing. For club racing or spirited practice sessions, this part helps maintain steady motor temps and reduces thermal strain on components.
