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

Upgrade the cooling on your Savage

The 3Racing HSA-027/G gold-coloured heatsink is purpose made for HPI Savage 21, Savage 25 and Savage X engines. Made from aluminium with 13 fins, it enhances heat dispersal from the cylinder head so engines run cooler under load. The compact, low-weight profile keeps handling unchanged while increasing thermal capacity.

Why this heatsink helps

High cylinder temperatures can affect tuning and reliability. The 3Racing HSA-027/G uses a dense fin arrangement to move heat away from the head more effectively, which supports more consistent running and can reduce temperature-related performance drops.

Compatibility and fitting notes

Fitted to the HPI Savage head pattern, this heatsink is a simple upgrade or replacement part. It is intended as a bolt-on improvement for users seeking better cooling without complex alterations.
