The Serpent 411217 centre spring is designed for S120L owners aiming to sharpen handling without losing traction. Its 18lbs rate balances stiffness and movement to help the layout feel more consistent lap after lap.
This spring helps maintain chassis balance on both smooth and slightly rough tracks, reducing unwanted squat and improving corner exit. Its sturdy build also reduces stress on adjacent suspension parts.
Installation on S120L chassis is straightforward, letting you test different preload settings fast. Combine with matching shock oils and pistons to tune response for local track conditions.
