This GPM aftermarket damper pair is engineered as a direct replacement and upgrade for HPI Savage 21 shock assemblies. Machined aluminium alloy bodies are supplied with fitted preload collars, mounting screws and a black dust-proof plastic cover to reduce debris ingress at the piston and seal interface.
Engineering and tuning notes: the 170mm length provides a consistent platform for controlled spring and oil tuning. The dampers are dimensioned to work with standard Savage 21 shock towers and mounting geometry, enabling predictable changes when adjusting spring rates, shock oil viscosity and ride height to refine on-track behaviour.
Assembly guidance: delivered as a 1pr kit with required mounting screws and alloy collars for standard shock posts. Typical installation requires only basic hand tools. During fitment confirm collar preload, thread engagement and full stroke clearance to avoid binding and ensure repeatable damping performance.
A precision-machined alloy damper option aimed at improved durability and consistent fitment for Savage 21 suspension tuning and routine maintenance.
