High oil-resistance soft shock O-ring

This soft O-ring is intended for RC shock assemblies and is made from a fluorine-based material with strong oil resistance to keep seal performance stable over extended use. The softer profile helps preserve piston contact and reduce stick-slip, supporting even damping feel during track sessions or practice runs.

The package includes a polyslider shim that can be fitted depending on the damper cylinder design to improve adhesion between O-ring and cylinder bore and lower the risk of oil seepage. Fit the shim when the damper shows slight leakage or when swapping between cylinder types to fine-tune sealing without changing internal components.

Installation is straightforward: remove the damper shaft and inspect the piston and cylinder for wear, replace the old O-ring with the YS-7HGCA unit, and add the polyslider shim only if the cylinder geometry or oil behavior suggests improved contact is needed. After reassembly, cycle the shock slowly to check for smooth travel and confirm there is no visible leakage.

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.

What is the O-ring material made of and why does it matter?

The O-ring uses a fluorine-based compound engineered for high resistance to common shock oils, which reduces swelling and helps the seal retain its shape and function over time.

When should I fit the supplied polyslider shim?

Fit the polyslider shim if you observe minor leakage or if the cylinder bore form reduces O-ring contact; for standard, well-matched cylinders the shim can be omitted.
