Tamiya 54093 TB-03 Aluminum Motor Heat Sink  [54093]

Efficient Motor Cooling with Tamiya 54093

Racing and track day drivers can use the Tamiya 54093 Aluminum Heat Sink to improve motor heat management on TB-03 chassis. This aluminium unit helps carry heat away from the motor during long sessions, supporting steady power delivery and reducing wear.

Designed for Longitudinal Motor Layouts

The Tamiya 54093 is modelled for longitudinally mounted motors and gives extra heat resistance where it matters. Fitting the sink reduces the risk of thermal sag, helping the motor hold rpm and torque under sustained load.

Fitment Notes for TB-03 and Evo5MS

Made for TB-03 use and compatible with the Evo5MS chassis in many setups, the heat sink requires checking pinion-to-upper deck clearance on Evo5MS installations to avoid gear interference.
