Spring cup and O-ring cap for pitching dampers

The Yokomo YX-40SC spring cup and O-ring cap are specified for pitching damper assemblies used on YR-X12 class 1/12 on-road cars. This part locates the spring and keeps the O-ring seated correctly inside the damper stack to support consistent performance.

Fit this component when you service or tune the pitching damper to restore proper spring seating and reliable O-ring placement. Follow standard RC maintenance practices when disassembling dampers and replacing internal parts to avoid damage.

Yes. The Yokomo YX-40SC is designed for the pitching damper assemblies used on YR-X12 class chassis and is also compatible with YR-X1219 units.

What installation steps ensure correct O-ring seating?

Clean the seating surfaces, check the O-ring for nicks, orient the cap to match the damper bore, and tighten the stack carefully so the O-ring is not pinched.

By maintaining consistent spring position and O-ring alignment, the part helps preserve damper consistency across rebuilds, which supports repeatable tuning changes.
