Stable Damping with Heavy-Duty Pistons

Race and club drivers looking for steadier suspension response will find the Yokomo S4-S182-25 pistons useful. Compatible with 13mm big bore shock bodies, these pistons combine a rigid 2.5mm section with two 1.8mm ports to regulate oil transfer for predictable compression and rebound behavior.

What You Get with Yokomo S4-S182-25

  • Thickness: 2.5mm for improved piston rigidity and consistent valve action.
  • Hole Diameter: Dual 1.8mm holes to balance flow and shock response.
  • Compatibility: Designed for SOR-030 and MOR-020 compatible 13mm shock units.
  • Package Includes: Set of 2 pistons.
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 changing to these affect ride height?

No direct change to ride height is expected since pistons alter damping not spring preload, but different damping can make the car feel higher or lower during dynamic movement.

Are these pistons suitable for off-road use?

They suit off-road conditions where improved damping control helps absorb repeated impacts, provided the shocks are 13mm big bore style and correctly set up.

How do I check fitment before sealing the shock?

Install the piston on the shaft and slide into the shock body, verify free movement and minimal lateral play, then test with a small oil amount before final assembly.
