Silicone Seal for High Big Bore Short Shocks

The Yokomo B9-S7SA silicone O-ring is made for high big bore short shocks, delivering a tight seal and strong durability. It is ideal for scheduled servicing and helps maintain consistent shock damping on Yokomo chassis, including models like MRTC-BD919 and MSR-010FEA. The resilient silicone material stands up to repeated use so your shocks stay leak free and predictable on the track.
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.

Which Yokomo chassis accept this O-ring?

This O-ring fits a range of Yokomo models, such as MRTC-BD919, MRTC-BD919S, MRTC-BD10FF, MRTC-BD11-1, MSR-BD11, MRTC-BD11US, MRTC-BD11A-1, MSR-010FE, and MSR-010FEA.

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

Replace the O-ring during regular shock service or sooner if you notice oil leaks, reduced damping, or visible cracking in the seal.

Any tips for fitting this O-ring to big bore shocks?

Clean the shock housing and shaft before fitting, seat the O-ring evenly, and use a drop of silicone-safe grease to ease installation and prevent pinching.
