The Serpent SER401765 pink shock spring offers reliable spring force and repeatable performance for the 4X EVO chassis. At C=7.2 these coils are aimed at drivers who fine tune chassis dynamics for corner entry and mid corner grip.
These springs are aimed at competitive hobbyists and weekend racers who need predictable handling changes when altering spring rate. They help smooth out transitions and keep the chassis composed through quick direction changes.
These units are produced to fit the 4X EVO and many common 1/10 dampers. Always check free length and internal damper travel before swapping to confirm the springs match your shock setup.
