Traxxas Revo 12 Fin Engine Heatsink by 3Racing RE-021/G  [RE-021/G]

Traxxas Revo heatsink overview

This 3Racing RE-021/G is an RC-scale engine heatsink styled for the Traxxas Revo platform, featuring a 12 fin layout and a gold color finish. It is presented as a chassis-level accessory meant to mount on the engine head to aid passive heat dissipation while the model is in operation.

Installation notes: the heatsink is intended to fit the engine head area on Traxxas Revo models, using the same fastening points as a standard head accessory. Check clearance around the air filter, carburetor, and body shell before final mounting. Verify screw length and thread engagement to avoid interference with the head or internals.

Tuning role: adding a finned heatsink can help stabilise head temperature under extended runs, which supports consistent engine behaviour on the track. Consider heatsink clearance when adjusting body height, intake orientation, or mounting additional accessories that sit above the engine.

Maintenance: keep fins free of packed dirt and fuel residue, inspect mounting screws periodically for tightness, and confirm there is no contact with moving parts after installation.
