This hardened steel shaft is a replacement for Sav13170 dampers used on HPI Savage 21 models and is supplied as 1 pr. The component functions as the internal damper rod and is intended for hobbyists performing shock servicing, rebuilds or component swaps.
Fitment requires standard shock disassembly, removal of the old shaft, and careful reassembly. Inspect seals and internal parts for wear during the service and confirm the new shaft is straight and moves freely to avoid uneven damping.
Use this shaft when restoring worn internals or when a damaged rod needs replacement to retain consistent suspension travel and predictable handling after a rebuild.
