High Seal O-ring for X30 Dampers

The Yokomo S4-S3XA O-ring provides an X-shaped sealing profile specifically for the X30 shock absorber, designed to reduce oil loss while preserving a low-friction feel. It suits racers who focus on consistent damper performance across varied track conditions.

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.

Is the S4-S3XA O-ring a direct replacement for stock seals?

For X30 shocks it replaces standard O-rings where specified, but check fitment before final assembly to confirm correct seating and clearance.

Will the seal affect damping feel?

The X-shaped geometry aims to keep sealing tight without adding noticeable stiction, so you should see steady damping rather than a heavier feel.

How often should I replace these O-rings?

Replace seals when you spot wear, cuts, or oil seepage; frequent track use may mean checking them every few maintenance cycles.

Any tips for extending seal life?

Keep shock shafts clean and lightly lubricated, avoid sand ingress, and use proper shock boots or protection where conditions demand it.
