These spring adjustment nuts are intended for X shock assemblies found on Yokomo R12 and GT series RC cars. As an aftermarket accessory, the nut lets you alter spring preload to tune suspension response without replacing springs or cutting into shock components.
By moving the spring seat the adjuster changes preload and static ride height, which helps refine traction and cornering balance during club runs or testing. The component is compatible with the X shock style used on the listed R12/GT models below.
This article describes an RC-scale accessory intended for use on compatible R12/GT chassis X shock assemblies only.
