Traxxas Revo Gold Head Heatsink 12 Fins - RE-021/G by 3Racing  [RE-021/G]

Revo engine heatsink notes

The 3Racing RE-021/G is a 12-fin replacement heatsink made for the Traxxas Revo platform, finished in gold to improve passive dissipation from the engine head. It is supplied as a chassis-level accessory to mount on the head and assist with head temperature control during longer runs.

Fitting advice: the heatsink is intended to attach using the same head screw points as standard Revo head accessories. During trial fitting check for clearance with the air filter, carburettor, and the inner edge of the body shell. Ensure screw length and thread engagement do not interfere with the head internals.

Tuning benefit: a well-placed finned heatsink can help reduce head temperature swings over extended running, supporting predictable engine response. Always consider the heatsink when adjusting body height or intake orientation.

Care and checks: clear fins of dust and fuel residue after use, check mounting screws regularly, and confirm there is no contact with moving parts once fitted.
