The Serpent SER401858 1.4mm antirollbar is a targeted upgrade for the Medius X20 series. It reduces chassis roll on tarmac and carpet tracks so the tyres stay planted and steering feels more predictable.
Designed for the Medius X20 MID 1/10 EP editions (SER400033 and SER400034), this antirollbar fits without major alterations. Installation is straightforward for anyone familiar with basic suspension swaps.
Choosing the 1.4mm bar gives a mid-range stiffness that trims unwanted roll but allows enough give to cope with small track imperfections, making it useful for both race and practice sessions.
