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

Steel+Delrin spring for Savage 21

This GPM aftermarket spring is an RC-scale replacement intended for the HPI Savage 21 chassis. It pairs a steel winding with Delrin seating to offer a durable spring element designed for use in Savage 21 shock assemblies as a direct replacement sold as 1 pr.

The component's role is purely within RC suspension and shock tuning, providing an option when stock springs need replacement or when a different mechanical response is required during setup. No real vehicle use is implied, this is manufactured for model-scale applications only.

Installation is straightforward for hobbyists familiar with shock service: disassemble the shock, swap the spring and retainers, then reassemble. Use standard RC shock service practice and inspect retainers and bearings during reinstallation, replace hardware if worn.
