Thermal Management for Competitive Use

The 3Racing RE-021/P heatsink provides a 12-fin aluminium profile with a protective purple anodize to enhance heat spread from the Traxxas Revo engine head. This component is intended for hobbyists and racers seeking improved passive thermal control without altering engine geometry.

Material and Fin Geometry

Fin count and spacing increase surface area to improve convective cooling. The anodized surface offers wear resistance while the profile balances airflow with clearance requirements around the head area.

Mounting and Setup Notes

Installation uses the stock Revo mounting points for a secure fit. During setup, confirm there is adequate clearance to adjacent parts and that fasteners are torqued to recommended levels to maintain contact and alignment.

How does fin geometry influence cooling under load?

Increasing fin area raises the interface for heat transfer into moving air, which reduces peak head temperature during sustained high RPM operation.

Any fitment checks for tuned engines?

Verify clearance with aftermarket heads, exhausts and airboxes. Confirm that the heatsink does not contact other upgrades that alter head height or surrounding geometry.

Recommended maintenance for race use?

Keep the fins free of oil and debris, inspect mounting points regularly, and avoid coatings that add thermal resistance to the anodized surface.
