HPI Savage 21 Replacement Shock Spring Steel+Delrin SAVSP by GPM  [SAVSP]

Steel spring with Delrin seats for Savage 21

This replacement spring is designed to fit the HPI Savage 21 shock assemblies and is supplied as a single pair. It combines a steel coil with Delrin seating to deliver a long-lasting spring element suitable for hobby-level suspension tuning.

Intended strictly for model RC suspension work, the spring gives an option when stock parts wear or a different mechanical response is required during setup. It is not suitable for any full-size vehicle application.

Fitting is simple for those familiar with shock service: remove the shock, swap the spring and retainers, then reassemble. Inspect the retainers and bearings and replace any damaged components as part of normal maintenance.
