Accurate shock setup for YZ-2/4 using the Yokomo Z2-S1722A

For modelers focused on setup precision, the Yokomo Z2-S1722A shock piston brings controlled oil flow to YZ-2/4 cars. Its pair of 1.7mm holes enables subtle changes to suspension response, and the 2.2mm thickness helps prevent flex under load so your settings stay consistent.

Main advantages of the Z2-S1722A piston

  • Compatibility: Made for the YZ-2/4 family and compatible with example models like B-YZ2DTM3 and B-YZ2CAL3.
  • Design: Twin 1.7mm apertures allow more nuanced damping tuning than single-hole pistons.
  • Durability: A solid 2.2mm section reduces wear and maintains shape during repeated runs.
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.

Do I need special tools to fit this piston?

No special tools are required beyond basic shock assembly gear; use a fine pick and clean cloth to avoid nicking the piston holes during installation.

Which situations benefit most from the dual-hole layout?

Tracks needing precise mid-speed compression control or environments where small damping changes alter lap time will see the biggest gains.

How do I check for wear on these pistons?

Inspect the holes for burrs, confirm roundness of the piston bore, and replace if oil leakage or uneven damping appears after repeated use.
