The Serpent 421091 Kingpin has been produced for the S240 '21 range to provide a firmer, more predictable steering pivot. Its accurate manufacturing reduces tolerance-related slack and helps maintain consistent handling over time.
Fitting this kingpin reduces unwanted steering movement and improves driver confidence when entering and exiting corners. It is intended for hobbyists and racers who prioritise repeatable steering behaviour and minimal maintenance interruptions.
