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

Compatibility and fit notes for pitching dampers

The Yokomo YOKYX-40SG shock spring is an R/C-scale replacement component intended for pitching damper applications on radio-controlled models. Identified by its gold finish, the spring is suited for situations that call for a dedicated pitching damper element within the suspension.

It is intended as a direct replacement where the damper accepts standard shock springs and is used to adjust pitching response and fine-tune front-to-rear weight transfer. Check spring orientation and preload clearance during fitting and compare results to a baseline to select the appropriate stiffness.

Inspect free length and straightness before installation, ensure the spring seats properly on shock cups and retainers, and confirm it does not bind on the shock shaft throughout full travel. These checks keep pitching damper response predictable.
