Pitching damper spring cup & O-ring cap

This Yokomo YX-40SC item is an RC-scale spring cup and O-ring cap set designed for use in the pitching damper assembly of YRX-12 class 1/12 on-road cars. It serves as the interface between the damper spring and the pitching damper housing, helping retain the spring and maintain O-ring seating within the damper stack.

Use this part when servicing or tuning the pitching damper to ensure consistent spring seating and reliable O-ring positioning. The component is intended for hobby-grade RC suspension work and should be handled with typical model-care practices when disassembling dampers and replacing internal parts.
