Silicon O Ring (Soft) for RC Dampers

The Yokomo YOKYS7S Silicon O Ring (Soft) 8pcs is a spare set of soft O-ring seals intended for use in RC-scale damper and shock assemblies. Each pack contains 8pcs fabricated as soft silicon O rings to provide compliant sealing where a softer seal is preferred for smoother piston movement or minor leak control.

These O rings serve as replacement sealing elements inside shock assemblies or on piston shafts where O-ring style seals are used. They are supplied in quantities suitable for multiple servos of small-scale dampers or for keeping a set of spare seals in your maintenance kit.

Installation is straightforward for anyone familiar with RC shock servicing: disassemble the shock cap or end, remove the old O ring, clean seating surfaces and lubricant traces, then fit the soft O ring into its groove before reassembling. No special tools are required beyond standard shock service tools and a clean work area.

In tuning practice, softer O rings like these change the friction characteristics at low shaft travel, which can affect initial feel and small-amplitude response of the damper. Use them when you need a slightly freer return or when replacing hardened, worn seals to restore smooth operation.

Keep these O rings as part of regular shock maintenance to maintain seal integrity and preserve consistent damper performance across runs.
