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

Replacement steel spring with Delrin seats for Savage 21

Designed for the HPI Savage 21 chassis, this aftermarket spring pairs a steel wound coil with Delrin seating and is supplied as one pair for straightforward replacement in Savage 21 shock assemblies.

Intended for RC suspension and shock tuning, it provides an option when stock units wear or to alter mechanical response during setup. It is manufactured for model-scale use and not for any real vehicle application.

Fitting is routine for those experienced with shock work: remove the shock, replace the spring and retainers, and reassemble. Check retainers, seals and bearings during service and replace any worn hardware to ensure correct function.
