3Racing F103GT-09A/LB Tamiya F103 Aluminum Motor Heatsink Street and Track  [F103GT-09A/LB]

Better motor cooling for Tamiya F103 cars

The Tamiya F103 line is a common choice for both hobby and competitive circuits. The 3Racing F103GT-09A/LB Aluminum Motor Heatsink is a compact upgrade that improves motor cooling. Constructed from aluminium with a light blue coat, the unit increases heat dissipation so motors maintain more stable temperatures during heavy use.

Practical cooling design

Compatible with the Tamiya F103, F103GT, and F103RM chassis, the heatsink keeps added weight low while offering a fin layout that improves airflow and thermal transfer. For regular track days or club racing, the part helps preserve motor performance and lowers the chance of heat related issues.
