3Racing HSA-027/G Gold Heatsink for HPI Savage 21/25/X  [HSA-027/G]

Cooling upgrade for HPI Savage engines

The 3Racing HSA-027/G gold-colored engine heatsink is made from high quality aluminum and is sized for the HPI Savage 21, Savage 25, and Savage X models. It uses 13 closely spaced fins to increase airflow around the cylinder head and reduce operating temperature during long sessions. The unit is light in weight so it adds cooling capacity without significantly increasing overall vehicle mass.

Benefits of the 3Racing HSA-027/G

Good thermal control is essential for nitro engines that see hard use. The 3Racing HSA-027/G delivers steady heat transfer through its precision-engineered fins, helping engines run more consistently and reducing stress on internal components. That can mean fewer temperature-related issues and more reliable power delivery on extended runs.

Fitment and fitting tips

This heatsink is manufactured to match the HPI Savage mounting pattern for an easy swap from stock parts. It is suitable for hobbyists upgrading worn stock heads or adding extra cooling for hot track conditions; basic hand tools are all that is required for installation.
