13mm Front Shock Spring Blue 3.7lbs Serpent 500908  [SER500908]

Tuning the front end with springs

The Serpent 500908 13mm front shock spring is a setup item for RC cars that alters front suspension characteristics through its 3.7lbs spring rate and blue finish. It is intended for tuning handling balance rather than modifying chassis structure.

Install only in shocks that accept 13mm coils; check spring seat fit, preload collar clearance, and shock shaft travel before fitting. Follow standard shock service: drain oil if required, disassemble, slide the spring onto the shock body, set preload at the collar, then reassemble and confirm unrestricted shaft movement.

Tuning tip: increasing front spring stiffness raises initial support and reduces dive under braking, while softening the spring can boost mechanical grip on bumpy tracks. Combine spring adjustments with damper oil and piston changes, and alter one setup item at a time to evaluate handling effects.
