The Serpent SER401835 shock cartridge stepped is designed for precision tuning on the Medius X20 MID 1/10 EP series. Its stepped internal profile provides distinct damping characteristics that help refine handling across different track sections.
Built with the Medius X20 MID mounting pattern in mind, this cartridge fits into compatible shock bodies and preserves the car's original suspension geometry. It is suited to drivers who want repeatable setup changes between events.
Fitting is a routine shock service task: extract the internal cartridge, install the stepped unit, refill with oil and bleed carefully. Check rebound and ride height after refit to confirm the desired behaviour on track.
