This Yokomo YAS-825A front shock spring is an RC-scale component built for high-grip carpet and artificial turf surfaces. It fits big-bore front shock assemblies and helps absorb jump impacts, lowers the risk of flipping on tacky surfaces, and supports a reduced ride height because of its compact free length.
In terms of setup, the spring acts as a tuning element rather than a standalone upgrade: it changes rebound characteristics, affects ride height, and alters chassis recovery behaviour after landings. Use it within a matched front-end setup to steady corner exits on carpet or astro turf while maintaining predictable compression and rebound response.
Installation notes: mount the spring to compatible big-bore front shock bodies using standard front-shock assembly procedures, verify correct preload and that the shock shafts move freely with the oil you select, and check clearance to prevent binding at full travel. No special tools beyond routine shock servicing equipment are necessary.
