Fine-Tune Suspension with Yokomo S4-S192-25 Pistons

Yokomo's S4-S192-25 shock pistons are made for hobbyists who want tighter suspension response. These SO/MO series pistons fit 13mm shocks and use a 2.5mm wall thickness to deliver more consistent damping. The two-hole layout, with bore sizes from 1.8mm to 2.0mm, helps control oil flow for predictable handling.

Performance Highlights

  • Precision Design: 2.5mm thickness increases damping control for sharper response.
  • Compatibility: Intended for SOR-030 and MOR-020 chassis configurations.
  • Durability: Constructed to stand up to frequent track use and repeated runs.
  • Easy Installation: Supplied as a pair for direct swap into existing shocks.
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 work in shock bodies from other brands?

These pistons are sized for 13mm Yokomo SO/MO series shocks and may not seat correctly in other-brand shock bodies without checking internal dimensions first.

How does the 2.5mm thickness change handling?

Thicker piston walls reduce flex and alter the flow timing through the two holes, producing firmer, more controlled damping especially on compressions.

Any tips for matching oil with these pistons?

Start with the oil weight you use now and test one step heavier or lighter to dial rebound and bump control; the two-hole layout reacts predictably to oil changes.
