Refine Dampers With Yokomo S4-S18213 Shock Pistons

Model engineers seeking better shock feedback can fit the Yokomo S4-S18213 pistons to 13mm dampers. The two 1.8mm holes fine-tune oil flow for steadier damping characteristics. They are intended for use with SOR-020 series chassis to help improve on-track composure.

Key Advantages of the S4-S18213

  • Precision Design: The twin 1.8mm ports moderate oil transfer to deliver more consistent compression and rebound control.
  • Durable Construction: Constructed to handle frequent tuning and competitive use.
  • Compatibility: Specifically matched to Yokomo SOR-020 and SOR-020D damper assemblies for direct replacement.
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 handling changes should I expect after fitting these pistons?

Expect subtler, more controlled shock reactions which can help the car track truer through corners and resist sudden weight transfer.

Can I swap these between front and rear shocks?

Yes, they are physically compatible with 13mm dampers front or rear, but you may need to adjust oil and valving to suit axle-specific demands.

How do I check for correct installation?

After assembly, compress the shock by hand to expel air and confirm smooth movement. Recheck seals and shaft alignment before refitting to the car.
