HPI Savage 21 Damper Internal Service Kit SAV13170/AD by GPM  [SAV13170/AD]

Savage 21 internal damper kit

This aftermarket set supplies the internal components used inside the shock body of HPI Savage 21 models. It is intended as a drop-in replacement for the parts that sit within the damper, focusing on the internal insert and valving pieces rather than external caps or springs.

The components restore the shock's internal assembly so each damper can be serviced or re-tuned. Common tasks include replacing worn inserts, swapping valving parts, or preparing the shock for a different oil grade to change damping response.

Installation requires partial shock disassembly to access the internals; work on a clean surface and reassemble carefully to prevent leaks and preserve damping behaviour. The item is supplied as a single aftermarket set for HPI Savage 21 maintenance and tuning jobs.
