Yokomo YAS-1000A Big Bore Rear Shock Spring (Black) for Carpet/Astro turf  [YAS-1000A]

Big Bore Rear Shock Spring Overview

This is an RC-scale big bore rear shock spring developed by Team Yokomo for artificial high-grip circuits featuring carpet and astro turf. The spring’s shorter overall length supports a lower ride height while maintaining jump control and corner stability on high-traction surfaces.

On carpet and artificial turf the spring helps produce smoother landings from jumps, reduces the tendency to catch the turf in tight corners, and mitigates the high-side roll that can occur on high-grip surfaces. It is intended for use in rear shock assemblies designed to accept big bore springs.

Installation and tuning notes: confirm the spring fits your shock’s inner and outer diameters and spring seat before installation, set preload and damping to suit the lower ride height, and use incremental changes when tuning to balance landing compliance with corner grip. This component is specifically an RC accessory and not for full-scale vehicles.
