Pitch-Control Shock Spring Yokomo YOKYX-40SS (Silver) for Pitching Damp  [YOKYX-40SS]

About the Pitching-Damp Spring

The Yokomo YOKYX-40SS is manufactured as an RC-scale spring for pitching-damp type shock assemblies and is offered as a replacement or tuning spring for general R/C shock units where pitch tuning matters. The silver finish is aimed at matching model styling preferences.

To install: remove the shock cap, compress the shock as needed, slide the spring over the damper shaft and seat it against the retainer or lower perch. Confirm correct seating and adjust preload before final assembly to ensure consistent movement and to prevent binding at full compression.

In tuning terms, the spring alters pitching characteristics: a harder spring increases resistance to nose dive and pitch during braking or acceleration, while a softer option permits more pitch motion and a gentler initial response. Use this spring alongside suitable damper oil and piston choices to keep balance, and assess handling changes on circuit runs.
