Fine-Tune Yokomo S4-S18213 Damping Response

RC racers and club drivers can use the Yokomo S4-S18213 pistons to dial in suspension behaviour. These pistons suit 13mm dampers and use two 1.8mm ports to refine oil flow, giving a clearer feel from the shocks. They are a practical upgrade for SOR-020 chassis owners aiming for crisper handling without major changes.

Main Benefits of the S4-S18213 Pistons

  • Precision Design: The twin 1.8mm holes control shock oil movement for a more predictable rebound and compression balance.
  • Durable Construction: Manufactured to endure regular track use and frequent setup changes.
  • Compatibility: Designed to fit Yokomo SOR-020 and SOR-020D dampers for a straightforward swap.
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.

How will the dual 1.8mm holes affect handling?

The paired holes change how quickly oil moves through the piston, which smooths transitions and helps the car settle faster over bumps and during direction changes.

Can I use these pistons in other 13mm dampers?

They are optimised for Yokomo SOR-020 and SOR-020D units. Other 13mm dampers may fit mechanically, but results will vary depending on piston and damper geometry.

Any setup tips when fitting S4-S18213 pistons?

Start with your regular shock oil and note changes in mid- and high-speed damping. Tweak oil weight and preload progressively to find the preferred balance for your track.
