Yokomo YOKYS7S 8pcs Silicon O Ring (Soft) for Damper Seal Replacement  [YOKYS7S]

Soft Silicon O Ring Seals for Shock Units

The Yokomo YOKYS7S Silicon O Ring (Soft) 8pcs supplies eight soft silicon O rings intended for RC shock and damper assemblies that employ O-ring seals. These soft rings are manufactured to provide compliant sealing where a lower contact force aids smoother piston travel.

They function as replacement sealing components inside shock bodies or on piston shafts fitted with O-ring style seals. The pack quantity is useful for keeping spares or servicing a set of small dampers during routine maintenance.

Basic installation requires typical shock servicing: open the shock cap or end, remove the old O ring, clean and inspect the groove and mating surfaces, then fit the new soft O ring ensuring it sits correctly before reassembly. A set of common shock service tools and a clean area are sufficient.

In terms of fit and function, softer O rings alter friction at initial shaft movement, which can influence the damper's feel and micro-response. Use these soft YOKYS7S rings when replacing hardened seals or when seeking a slightly less resistant return.

Store a pack of these O rings with your maintenance supplies to preserve sealing performance and ensure reliable damper operation.
