Yokomo YOKYS7S Soft Silicon O Ring Set 8pcs for RC Damper Seals  [YOKYS7S]

Soft Silicon O Rings for RC Dampers

The Yokomo YOKYS7S Silicon O Ring (Soft) 8pcs are replacement soft O-ring seals made for small-scale RC damper and shock assemblies. Each pack supplies eight soft silicon rings designed to give a compliant seal where reduced friction and smoother piston movement are desired.

These O rings are intended as direct replacement sealing elements inside shocks or on piston shafts that accept O-ring style seals. The 8pcs count suits keeping a spare set for routine maintenance or for service of multiple small dampers.

Fitting is simple for hobbyists experienced with shock servicing: remove the shock cap or end, extract the old O ring, clean the seating surfaces and any lubricant residue, then seat the new soft O ring into its groove before reassembly. No specialty tools are required beyond standard shock service tools and a tidy workspace.

In practice, swapping to softer O rings alters low-travel friction and can change initial damper feel and small-amplitude response. Use the soft YOKYS7S rings when you want a freer return or to replace hardened seals to restore smooth action.

Carry a pack of these O rings in your maintenance kit to preserve consistent damper performance and prevent leaks during regular servicing.
