Yokomo YOKYS7S 8pcs Soft O Rings for RC Shock Tuning  [YOKYS7S]

Soft Silicon O Rings to Tune Damper Feel

The Yokomo YOKYS7S Silicon O Ring (Soft) 8pcs is a spare set of soft silicon O-ring seals intended for RC shock and damper assemblies. Each pack contains eight soft rings intended to alter friction characteristics where a softer sealing surface is wanted for smoother piston action.

These rings act as replacement seals within shock assemblies or on piston shafts that take O-ring style seals. The eight-piece quantity is practical for servicing multiple small dampers or keeping spares in a tuning kit.

Installation is a routine shock service task: remove the shock cap or end, take out the worn O ring, clean the seating surfaces of oil and debris, then press the soft O ring into its groove prior to reassembly. Standard shock tools and a clean bench are all that are needed.

From a tuning perspective, softer O rings influence low-travel friction and can modify the damper's initial feel and micro-response. Choose these soft YOKYS7S rings when aiming for a freer return or to replace old, stiff seals to regain smooth operation.

Keep a spare pack on hand in your tuning kit to quickly experiment with seal softness and maintain consistent shock performance.
