This GPM aftermarket set is an RC-scale replacement intended for HPI Savage 21 shocks, combining the shock connector and a 1.3mm damper spring in a 113mm length. The parts are supplied as one pair (1pr) and are intended to replace worn shock springs and connectors or to provide an alternate damping option when servicing the vehicle's suspension.
The components serve a maintenance and tuning role: the spring changes the shock’s stiffness and the connector ensures correct linkage between the shock assembly and suspension mounting. Installation requires standard shock disassembly and reassembly procedures for Savage 21 shock bodies and does not alter non-RC components. Check fitment against your shock length and mounting points before installation.
