The Serpent 402020 Topdeck Insert is a finely made upgrade for the X20 '23 chassis that reduces flex and sharpens vehicle responses. It integrates into the original chassis layout to deliver added structural support where chassis twist is most noticeable.
By stiffening the chassis, this insert helps the suspension and tyres do their job more effectively, giving clearer feedback through corners. That predictability makes it easier to dial in your setup for qualifying and race conditions.
