Tune Chassis Rigidity on the Serpent X20

The Serpent SER401909 topdeck flex post provides a simple way to alter rigidity across the upper deck of the Medius X20 FWD 1/10 EP series. It helps control body flex so the car tracks truer through fast sections and chicanes.

Performance Impact of the SER401909

By supporting the upper deck, the SER401909 reduces unwanted twist and promotes more consistent tyre contact. Drivers will notice improved predictability during cornering and under braking without drastic changes to the stock setup.

Which Models Fit and How to Install

This component fits the Medius X20 MID Series, including X20 FWD 1/10 EP models (SER400035 and SER400036). Installation is straightforward and suitable for hobbyists comfortable with basic assembly steps.

Will the post make the car more responsive on high grip surfaces?

On higher grip tracks the reduced flex can sharpen response, though you may need to soften other areas like suspension or tyres to keep a balanced feel.

Can I use this with aftermarket shock setups?

Yes, it works with most aftermarket damper configurations; adjustments to damping and spring rate help integrate the changed flex profile.

Is the part reversible if I prefer the original feel?

The installation is non-destructive so you can remove the post and return to stock flex characteristics if desired.
