Upgrade Your Damping with Robust Pistons

For drivers chasing more consistent suspension performance, the Yokomo S4-S182-25 pistons are a solid option. Made for 13mm big bore shocks, the 2.5mm construction and paired 1.8mm holes improve oil flow control and reduce unwanted shock variation during extended runs.

Technical Highlights for Yokomo S4-S182-25

  • Thickness: 2.5mm to increase piston stiffness and improve valve stability.
  • Hole Diameter: Twin 1.8mm ports to refine damping characteristics.
  • Compatibility: Intended for SOR-030 and MOR-020 13mm shock assemblies.
  • Package Includes: 2 pistons per pack.
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.

Can I use these with lightweight shock shafts?

They work best with shafts that match standard 13mm big bore tolerances; very thin or undersized shafts may cause excess play and reduce effectiveness.

Which oil should I pair with these pistons?

Choose oil weight based on track conditions and vehicle weight; mid-range viscosities are a good starting point to exploit the twin 1.8mm ports without making the shocks too slow.

Do they improve durability?

The thicker 2.5mm piston is less prone to deformation under load, which can lead to more consistent damping and longer service life in demanding use.

How many come in a set?

Each package contains 2 pistons, suitable for replacing a pair of shocks or keeping a spare for maintenance.
