Shock piston for off-road dampers

This Yokomo YS-8-142 F. Shock Piston is an RC-scale replacement piston intended for off-road shock assemblies. It alters internal flow characteristics inside the damper body to help refine rebound and compression feel without changing other shock components.

Installation is straightforward for anyone familiar with threaded shock bodies: disassemble the shock, remove the shaft and spring, swap the piston, reassemble using the same seals and shock oil grade you already use. Small changes in piston size or hole count affect how oil passes through the piston, so use this part to tune mid-range and low-speed damping rather than as a wholesale performance upgrade.

Use this piston as part of step-by-step tuning: test one change at a time, note handling differences on a representative surface, and rotate through oil weights or spring rates only after observing the piston effect. This keeps setup adjustments predictable and repeatable.

Remark :

Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

What does the "1.4" in the name indicate?

The product name includes "1.4" to denote the piston sizing used to describe its flow profile, use it to compare relative sizes when changing pistons.

Can I install this in any off-road shock?

It is designed for off-road RC dampers, but confirm piston diameter and shock shaft clearance before fitting to ensure proper operation.
