Dial In Suspension With Yokomo S4-S18213 Pistons

For model builders wanting cleaner shock feedback, the Yokomo S4-S18213 pistons are a solid option. Made for 13mm dampers, the dual 1.8mm ports moderate oil flow to deliver steadier damping. They integrate neatly with the SOR-020 family to help you refine corner entry and mid-corner balance.

Why Choose the S4-S18213 Pistons

  • Precision Design: Two 1.8mm holes tune the oil passages to reduce harsh transitions and stabilise rebound.
  • Durable Construction: Built to tolerate frequent running and trackside adjustments.
  • Compatibility: Intended for Yokomo SOR-020 and SOR-020D chassis for straightforward installation.
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.

Will these pistons make the car softer or firmer?

They adjust flow rather than spring rate, so you can see changes in how the damper controls speed of travel without altering spring stiffness.

Are there installation tricks for SOR-020 dampers?

Ensure the piston is centred on the shaft and that seals are clean. Bleed the shock carefully to avoid air pockets for consistent results.

How do I assess if the pistons suit my setup?

Compare lap times and handling feel before and after the swap, focusing on mid-corner stability and how the car reacts to small bumps.
