The Yokomo BM-S152A shock piston is an essential part for drivers wanting to dial in suspension behaviour. With two precise 1.5mm openings, it delivers smoother damping and sharper control on race layouts.
A clear hole diameter stamp on the front makes size identification fast, while a guide mark on the back lets you add more holes if required. This flexibility helps you match damping to track grip and driving style.
Compatible with a range of Yokomo B-YZ models such as B-YZ2, B-YZ2CA and B-YZ4SF, the piston is a practical upgrade for racers aiming to improve suspension response and stability.
