The Yokomo BM-S152A shock piston gives hobbyists a precise tool for tuning suspension behaviour. Its two accurate 1.5mm holes help regulate damping for cleaner handling on a variety of surfaces.
The piston is marked on the front with the hole diameter for quick checks, and a rear guide mark makes it straightforward to add extra holes if you want greater oil flow. That makes progressive tuning easier during setup sessions.
Designed to be compatible with many Yokomo B-YZ models including B-YZ2, B-YZ2CA and B-YZ4SF, this piston is useful for drivers working to refine suspension response and track stability.
