Serpent SER401839 Aluminium Shock Adjuster Nut with O-Rings  [SER401839]

Upgrade your Medius X20 MID suspension with Serpent SER401839

Owners of the Medius X20 MID series will find the Serpent SER401839 shock adjusting nut useful for accurate suspension trimming. Built from aluminium and fitted with o-rings, it offers a positive, anti-rotation fit that helps keep settings stable during practice and racing.

Designed for Medius X20 MID chassis

The adjusting nut is made to match the Medius X20 MID 1/10 EP models (SER400033 and SER400034). Its lightweight aluminium construction preserves durability while helping the car feel more responsive through corners.

How to fit and maintain the adjuster

Push each o-ring onto the nut so it sits flush before fitting to prevent movement under load. Recheck nut tightness after a few runs and replace o-rings if they lose elasticity to maintain consistent ride height and damping performance.
