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

Revo head heatsink summary

This 3Racing RE-021/G is a 12-fin engine heatsink made for the Traxxas Revo chassis, finished in gold to add surface area for passive cooling when the model is running. It mounts at chassis level on the engine head and is intended to help stabilise head temperature during longer sessions.

Installation notes: the heatsink is designed to use the engine head's existing fastening points on Traxxas Revo models. Check clearance around the air filter, carburettor, and body shell before final fitting. Confirm screw length and thread engagement to prevent interference with the head or internal components.

Tuning role: adding a finned heatsink can help keep head temperature steadier across extended runs, which supports consistent engine behaviour on the track. Keep heatsink clearance in mind when setting body height, intake position, or mounting accessories above the engine.

Maintenance: clear fins of packed dirt and fuel residue after running, inspect mounting screws for tightness, and ensure the heatsink does not contact moving parts once installed.
