Overview for Revo head cooling

The 3Racing RE-021/G is a 12-fin head heatsink crafted for the Traxxas Revo platform, finished in gold to boost heat dispersion through increased surface area. It fits at the engine head region and is intended to lower peak head temperatures during longer runs.

Installation advice: this heatsink is made to align with the standard head mounting points on Traxxas Revo models. Always check clearance to the air filter, carburettor, and body shell during mock-up. Verify screw length and engagement to avoid contact with the head internals.

Tuning impact: a finned heatsink helps reduce temperature swings over sustained operation, aiding more consistent engine performance. Factor in the heatsink height when setting body clearance, intake angle, or attaching above-engine accessories.

Care tips: keep fins free of grit and fuel deposits, tighten mounting hardware as required, and make sure there is no interference with moving parts after installation.

Is the RE-021/G compatible with modified Revo heads?

Compatibility depends on the head's bolt pattern and clearance after any porting or machining; measure your modified head before fitting the heatsink.

Will the heatsink affect air filter placement?

Potentially—check filter and intake clearance during installation and adjust body or filter position if necessary to prevent contact.

Any maintenance to keep performance consistent?

Regularly clean fins, inspect the finish for corrosion or fuel damage, and confirm screws remain tight after a few runs.
