Yokomo YAS-1000A Short-Length Big Bore Rear Spring for Carpet and Astro Turf  [YAS-1000A]

Optimised Short-Length Big Bore Spring

The Yokomo YAS-1000A is a big bore rear shock spring engineered for artificial high-grip surfaces such as carpet and astro turf. Its reduced length supports a lower ride height while aiming to keep jump control and cornering stability consistent.

On high-traction surfaces this spring smooths out landings, helps prevent the tyre or chassis catching turf in tight turns, and reduces sudden roll tendencies. It is intended for use with rear shock setups that accept big bore springs.

Tuning notes: confirm inner and outer diameter compatibility and that the spring seats correctly on your shock. When adjusting, change damping and preload incrementally to find the balance between compliant landings and steady corner grip. This component is designed for RC models only.
