The Serpent SER401765 shock spring in pink is made to deliver steady, predictable suspension behaviour for the 4X EVO. With a spring rate of C=7.2 these springs help you dial in mid corner grip and rebound feel without surprises.
Built for track-focused setups, these springs let racers adjust roll and weight transfer to match different asphalt surfaces. They provide the kind of feedback racers rely on when trimming handling under changing conditions.
Made to fit the 4X EVO chassis, the Serpent springs install easily into standard 1/10 scale dampers and work with common shock hardware. Verify fit on other models before swapping to ensure correct travel and preload range.
