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

Steel coil and Delrin seating for Savage 21 shocks

This aftermarket spring is a direct-fit replacement for the HPI Savage 21 chassis, combining a steel wound coil with Delrin seating to provide a durable spring element for Savage 21 shock assemblies. The item is supplied as 1 pr for simple swap-in replacement.

Built for RC suspension and shock tuning, it is intended to replace worn stock springs or to tune mechanical response during setup. It has no application on full-size vehicles and is made for model-scale use only.

Installation is straightforward for hobbyists familiar with shock service: disassemble the shock, remove the old spring, fit the new spring and retainers, then reassemble. Follow standard RC shock maintenance and inspect retainers and bearings, replacing any worn hardware.
