Improve chassis control with the Serpent 421040 for S240

The Serpent 421040 Shock Spring is a practical upgrade or spare for the S240 Electric Pancar, aimed at improving suspension stability. It helps the car resist bottoming and keeps tyre contact consistent over rougher sections of a race circuit.

Made to withstand regular race sessions

With careful manufacturing, the Serpent shock spring maintains its shape and rate over time, supporting repeated use at club and regional events. That resilience reduces the need for frequent replacements during busy race seasons.

Simple fitment and common use cases

This spring is compatible with the Serpent S240 Electric Pancar and fits standard shock assemblies. Install it to refresh worn springs or to change handling balance when testing different setups.
