Yokomo YOKYX-40SG Shock Spring (Gold) for Pitching Damp  [YOKYX-40SG]

Pitching damp shock spring for R/C models

This Yokomo YOKYX-40SG shock spring is an R/C-scale replacement part intended for pitching damp applications on radio-controlled models. The component is identified by its gold finish and is intended to be used where a dedicated pitching damper spring is required, serving a tuning role within the vehicle's small-scale suspension system.

Use notes focus on role and basic fitment: the spring is meant as a direct replacement for springs used in pitching damp assemblies on R/C models that accept standard shock springs, and is intended to alter pitching response and fine-tune front-to-rear weight transfer behavior. When installing, check spring orientation and preload clearance in the damper assembly, and compare response against the baseline setup to determine whether a firmer or softer spring best meets your handling goals.

Maintenance and inspection are straightforward: inspect for consistent free length and straightness before use, confirm clean seating on shock cups and retainers, and verify that the spring does not bind on the shock shaft throughout full travel. These checks help maintain predictable pitching damper response during track or practice sessions.
