Serpent SER401853 springs give tuners a compact way to change suspension behaviour on the Medius X20 MID 1/10 EP platform. They are sized for the X20 Series and let you refine front and rear compliance.
These springs help adjust body roll and mid corner support so you can fine-tune grip and rotation. Use them alongside small shock adjustments to dial in lap consistency.
Made to work with the Medius X20 MID Series, the springs install into the existing shock assemblies without special modifications. Basic setup checks after fitting will get you track ready.
