Optimising pitching damper spring seating

The Yokomo YX-40SC spring cup and O-ring cap are aftermarket service parts intended for pitching damper systems on YR-X12 class 1/12 on-road cars. The component centres the spring and secures the O-ring so the damper stack performs predictably during tuning.

Fit this item when adjusting damping characteristics or rebuilding the pitching damper to regain correct spring placement and O-ring alignment. Observe normal workshop precautions when handling small damper parts.

Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How will swapping this part affect damper feel on track?

Replacing a worn cup or cap restores consistent spring location and O-ring position, which can make damper responses more repeatable and easier to fine-tune during setup changes.

Can I use this when changing spring rates?

Yes. When you fit different springs, the YX-40SC helps maintain correct seating so spring preload and travel remain consistent after reassembly.

Any assembly practices to aid tuning consistency?

Ensure the cap is properly aligned, check the O-ring for correct compression, and mark stack positions if you need to reproduce settings between runs.
