Refine Chassis Behaviour on the Serpent X20

The Serpent SER401909 topdeck flex post is a targeted upgrade for drivers seeking more consistent chassis behaviour from the Medius X20 FWD 1/10 EP lineup. It reduces upper-deck movement so handling becomes more predictable across different track conditions.

What the SER401909 Delivers

Installing the SER401909 adds extra upper-deck support to lower chassis twist and help retain setup geometry under load. This often translates to steadier cornering lines and improved confidence when pushing the car hard.

Compatibility Details and Fitting Advice

The post is compatible with the Medius X20 MID Series and fits X20 FWD 1/10 EP models (SER400035 and SER400036). The fitment process is simple and suitable for most hobbyists without the need for specialist tools.

How will this affect lap-to-lap consistency?

By stiffening the upper deck the part helps reduce variable flex, which improves repeatability and makes setup changes more predictable.

Are there any setup changes recommended after fitting?

Minor adjustments to sway bars, shock piston selection or spring rate can help match the new stiffness to your preferred handling balance.

Will this part work with both stock and upgraded decks?

It is designed for the standard Medius X20 upper deck but will generally integrate with common aftermarket deck options that share the same mounting points.
