3Racing HSA-027/R Red Engine Heatsink for HPI Savage 21 25 X  [HSA-027/R]

Cooling upgrade for HPI Savage powerplants

The 3Racing HSA-027/R red engine heatsink is made for HPI Savage 21, 25, and X models. Its 13-fin aluminium body increases surface area to pull heat away from the cylinder head, helping the motor stay within a safer operating range during heavy use. Better heat control helps avoid thermal stress and keeps running smoother over long sessions.

Manage temperatures for steadier output

Excess heat can cause power loss and accelerated wear. This 3Racing heatsink spreads heat across its fins to speed cooling and reduce temperature spikes. The result is a more reliable engine response and fewer heat-related issues on the track.

Direct fit for Savage series models

Designed to mount cleanly on HPI Savage 21, 25, and X engines, the heatsink installs without alterations thanks to its precise dimensions. Whether you race regularly or run bash sessions, this upgrade gives a practical improvement in thermal performance and component life.
