Refined Shock Performance with Solid Pistons

For hobbyists tuning handling precision, the Yokomo S4-S182-25 offers dependable improvements. These pistons are built for 13mm big bore shocks and use a 2.5mm body with two 1.8mm holes to regulate internal oil flow, promoting smoother compression and rebound across varied surfaces.

Feature Summary for Yokomo S4-S182-25

  • Thickness: 2.5mm to resist flex and maintain consistent damping behavior.
  • Hole Diameter: Twin 1.8mm ports to help fine-tune oil movement.
  • Compatibility: Suitable for SOR-030 and MOR-020 13mm shock assemblies.
  • Package Includes: Two 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.

Do these pistons require a specific shock oil?

No single oil is required, but pairing with a viscosity that complements the twin 1.8mm ports will give the best balance between response and control for your vehicle weight and track surface.

Can these reduce fade during long runs?

A firmer piston like this can reduce performance variation as oil heats, helping maintain more consistent damping over longer sessions compared with very flexible pistons.

Will they fit sealed shock kits?

They are intended for rebuildable 13mm big bore shocks; sealed, non-serviceable units may not permit piston replacement.

What maintenance do these pistons need?

Inspect for scoring or wear during routine shock rebuilds, clean thoroughly, and replace if the ports or edges show damage to preserve consistent damping.
