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

Improved head cooling for Savage nitro engines

The 3Racing HSA-027/G gold finish heatsink is intended for the HPI Savage 21, Savage 25 and Savage X engines. Built from aluminium and incorporating 13 fins, it raises the effective surface area to help shed heat during heavy usage. The unit is lightweight so it gives a cooling upgrade without a hefty weight penalty.

Advantages for extended running

Heat control matters when you push nitro engines for long periods. The 3Racing HSA-027/G helps to maintain more even operating temperatures thanks to its fin pattern, which can contribute to steadier power and reduced thermal wear over time.

Fitment overview

This part matches the HPI Savage mounting geometry for direct replacement of the standard head heatsink. It is well suited to those upgrading worn components or fitting additional cooling for competitive practice sessions.
