Competitive drivers refining suspension balance will benefit from the Yokomo Z2-S1622A piston. Built for X33 shock systems, it features two 1.6mm holes and a 2.2mm plate, providing controlled oil flow to improve handling and stability during spirited laps.

Suitable Models

The Yokomo Z2-S1622A fits multiple Yokomo variants including B-YZ2DTM3, B-YZ2DTM31-1, SOR-010, B-YZ2CAL3, B-YZ2CAL31-1, ROR-010, ROR-010RTR, and ROR-010RTR-1. Use it when you need repeatable damping characteristics for track tuning.
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 are the piston hole measurements?

The piston has two holes, each 1.6mm across, which determine the basic flow rate for tuning.

Is this a direct replacement for stock pistons?

Yes, it replaces compatible X33 pistons and installs like other OEM-style pistons in the specified models.

How should I use this for setup work?

Start with recommended oil weights for X33 shocks and then swap piston or oil viscosity to tune mid and high speed damping to suit the circuit.
