X-shaped O-ring for Reliable X30 Shocks

The Yokomo S4-S3XA O-ring uses an X-shaped profile crafted for the X30 shock absorber to strengthen sealing while keeping operational drag low. It helps maintain consistent damping and reduces the need for frequent top-ups.

Supported Yokomo Chassis

Fits an array of Yokomo chassis, listing B-YZ4SF2-1, MOR-010, B-YZ2DTM31-1, B-YZ2CAL31-1, SOR-010, MOR-020, SOR-020, MSR-010, MSR-010A, SOR-020D, ROR-010, ROR-010RTR, and ROR-010RTR-1. Useful for routine maintenance or when upgrading sealing components.
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.

How do I know when to replace the O-ring?

Replace when you see oil weeping, visible cuts, or if the seal no longer returns to shape after compression. Regular inspection during service intervals catches wear early.

Will this O-ring improve handling directly?

Improved sealing reduces oil loss and inconsistent damping, which in turn supports more predictable handling; it is part of a wider setup strategy rather than a single-handling fix.

Is special lubrication required for the seal?

A light coat of compatible silicone grease during installation helps seating and prevents dry friction, but avoid heavy greases that can attract dirt.

Can I run these on-road and off-road setups?

Yes, the S4-S3XA suits X30 shocks used in different disciplines; just keep up with cleaning and inspection when running in dusty or wet conditions.

Where should I source replacements and spares?

Obtain genuine parts from authorised suppliers or reputable hobby stores to ensure correct fit and material quality for the S4-S3XA O-ring.
