Improved Cooling for Traxxas Revo Engines

The Traxxas Revo engine heatsink by 3Racing, RE-021/P, uses a 12-fin profile and purple anodized finish to boost air contact and reduce head temperature during extended running. This passive cooling upgrade helps the engine hold a steadier temperature so power delivery remains consistent through long sessions.

Designed for Track and Trail Use

Built to match the Traxxas Revo layout, the heatsink blends practical thermal performance with a durable anodized coat. The fin geometry promotes airflow around the cylinder head while the finish resists everyday wear.

Plug and Play Fitment

The 3Racing RE-021/P installs directly on the Revo engine without modifications, lining up with stock mounting points to give hobbyists an easy performance upgrade.

How does the 12-fin profile improve cooling?

Increasing the number of fins raises the total surface area exposed to air, which helps dissipate heat faster from the engine head during sustained runs.

Will I need to modify my Revo to fit this heatsink?

No modifications are required for standard Traxxas Revo engines; the heatsink is designed to mount using the factory screw points for a straightforward swap.

Does the purple anodize affect thermal performance?

The anodized finish provides corrosion resistance and durability. Avoid heavy paint or insulating coatings, as those can reduce heat transfer efficiency.
