Track-Ready O-Rings for Yokomo S4-S3OS Shocks

The Yokomo S4-S3OS O-Ring Set comes with two bottles of purpose-made O-rings for 13mm big bore shocks, configured for the SO/MO2.0 chassis series. They cut down internal friction and reinforce sealing so shocks stay consistent under repeated runs and hard use.

Benefits for Tuners

  • Lightweight Design: Reduced mass helps the suspension react faster to bumps and direction changes.
  • Enhanced Durability: Durable material stands up to frequent compression cycles and track abuse.
  • Compatibility: Precisely sized for Yokomo SO/MO2.0 chassis to ensure correct fitment and leak control.
  • Performance Boost: Smoother internals let you make finer adjustments to damping and rebound.
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.

Can I use these O-rings on older big bore shocks?

They will work on older 13mm big bore units if the seal groove and internal dimensions match. Verify the shock bore and groove size before fitting.

Will these O-rings improve rebound consistency?

By reducing seal friction and preventing leaks, these O-rings help maintain steady rebound characteristics throughout a race, making setups more predictable.

Any recommended installation tools to avoid damage?

Use soft plastic tweezers or a blunt, non sharp pick and fit rings dry first. Lightly coat with shock oil only after they are properly seated to avoid nicks or twisting.
