The Tamiya 54040 Aluminum Motor Heat Sink is a practical upgrade for DB01 chassis owners. Built to improve heat transfer, this heat sink helps your motor shed heat quicker so it holds power and reliability during extended running sessions.
This aluminum heat sink is made to match the DB01 chassis and increases surface area for better heat dispersion. Lower operating temperatures reduce thermal throttling and help preserve motor efficiency when the track or trail gets demanding.
The Tamiya 54040 fits DB01 chassis cars and pairs well with the 54041 DB01 Carbon Reinforced Chassis for a stiffer, cooler setup. You can fit it on a standard DB01, but using the two together gives the most consistent results for heavy use.
