Traxxas Revo 12-Fin Heat Spreader RE-021/P by 3Racing  [RE-021/P]

Heatsink features and appearance

This 12-fin heat spreader is an aftermarket styling and cooling accessory made to suit Traxxas Revo engine heads. The item is listed as model RE-021/P and comes in a purple finish to complement Revo builds.

The device acts as a passive heatsink by increasing the head's exposed area, improving heat dissipation during extended running or heavier workloads. The result is typically steadier running temperatures and reduced thermal fluctuation.

Installation notes: the part is formed to align with the Revo head profile, so confirm clearance with your body shell, head studs and tuned pipe routing prior to installation. Ensure fastener length and head height are compatible to prevent contact with other chassis parts.

Use in tuning: integrate this heatsink with proper body airflow and engine setup to support thermal management; it does not change internal engine timing or fuel requirements but aids consistency.

A reversible, low-risk hop-up for Revo owners after extra passive cooling and a purple aesthetic; always check fitment before fitting.
