Want more predictable suspension behaviour? The Serpent SER401840 3-hole shock piston is a straightforward upgrade for Medius X20 cars that helps tame sudden weight shifts and improves overall composure.
The three-hole pattern moderates fluid flow to smooth out compression and rebound transitions. That consistency translates into steadier traction and better driver confidence lap after lap.
Designed for the Medius X20 MID 1/10 EP models (SER400033 and SER400034), the piston fits into the stock shock stack without modification. Install it during routine service or when testing new damper settings.
