The Serpent 421091 Kingpin is a direct-fit upgrade for the S240 '21 that sharpens steering input and improves front-end stability. Manufactured to strict tolerances, it is a practical part for racers wanting a reliable steering pivot under load.
Using this kingpin reduces unwanted movement in the steering knuckle and helps drivers get repeatable behaviour through a variety of corner types. The stronger construction is aimed at frequent racers and those who run harder compounds or more aggressive setups.
