HPI Savage 21 Damper Rebuild Inserts SAV13170/AD by GPM  [SAV13170/AD]

Savage 21 shock internal components

This aftermarket item supplies the internal pieces meant to be fitted inside the shock body on HPI Savage 21 vehicles. The kit targets the inner insert and valving parts rather than external caps, springs or mounting hardware.

The set helps you restore the internal damper assembly so the shock can be rebuilt for maintenance or tuned for performance. Common uses are replacing worn inserts, swapping valving elements, or prepping the shock for a different oil viscosity to change damping behaviour.

Accessing these parts requires partial disassembly of the shock; carry out the work on a clean bench and reassemble carefully to avoid oil leaks and to keep damping consistent. Supplied as a single aftermarket set for Savage 21 shock servicing and tuning tasks.
