3Racing Traxxas Revo 12-Fin Engine Heatsink RE-021/P - Replacement Part  [RE-021/P]

Overview and intended use

A purple-finished 12-fin heatsink intended as an aftermarket accessory for Traxxas Revo engine heads. The unit is identified as model RE-021/P and provides a simple, reversible visual and thermal upgrade.

The heatsink increases the head's exposed surface area to passively dissipate heat, helping to stabilise temperatures during prolonged operation or under heavier loads. It is a cooling aid rather than an active performance mod.

Installation notes: designed around the Revo head profile, so inspect body shell clearance, head stud positions and tuned pipe routing before mounting. Confirm screw lengths and head height to avoid interference with nearby components.

Tuning note: this heatsink supports thermal stability when used with correct airflow and engine tuning; it will not change internal timing or fuel requirements but can aid consistent running.

A practical, low-impact upgrade for Revo owners seeking passive heat control and a purple styling touch; check compatibility with your specific chassis before ordering.
