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

Rear Spring Technical Summary

The Yokomo YAS-1000A is a big bore rear shock spring developed for high-traction artificial surfaces like carpet and astro turf. Its shorter overall length lowers ride height while aiming to preserve jump control and cornering stability.

On carpet and turf the spring smooths landing transitions, decreases the chance of the chassis catching the surface in tight turns, and helps limit high-side roll tendencies. It is supplied for use in rear shock setups that accommodate big bore springs.

Setup tips: confirm spring compatibility with your shock’s inner/outer diameters and seat design, then adjust preload and damping stepwise to suit the reduced ride height. Always test changes incrementally to balance cornering grip against landing softness. This item is an RC accessory only.
