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

Carpet and Astro Turf Spring Overview

This big bore rear shock spring from Yokomo, model YAS-1000A, is designed specifically for artificial high-traction circuits featuring carpet and astro turf. The reduced overall length gives a lower ride height while helping preserve jump control and corner stability on grippy surfaces.

On carpet and artificial turf this spring provides smoother landings from jumps, lowers the chance of catching turf in tight turns, and reduces the tendency to roll over on high-grip layouts. It is intended for rear shock assemblies that accept big bore springs.

Installation and tuning guidance: verify the spring matches your shock’s inner and outer diameters and spring seat before fitting, adjust preload and damping to suit the lower ride height, and tune in small steps to balance landing compliance with corner grip. This part is an RC accessory and not for use on full-scale vehicles.
