Dedicated pitching spring for YR-X12 1/12 dampers

Built for pitching dampers on 1/12-scale on-road competition cars, this black spring carries a volume 5.0 mark and acts as a replacement component for the YR-X12 series. It delivers a consistent spring rate within the damper stack to help control nose pitch during braking and acceleration phases.

Fitting is simple for experienced tuners: open the pitching damper, extract the old spring, place the Yokomo YX-40SBK into the retainer, then reassemble and confirm unobstructed movement. Typical damper service tools are all that is required.

When tuning, consider the YX-40SBK as one factor in front-end balance. Its volume 5.0 classification should be tested with different damper oils and piston options to fine tune corner entry and exit behavior on the YR-X12 chassis.

Compatibility

  • YR-X12
  • YR-X1219
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.

Does the YX-40SBK change how the car responds mid-corner?

Yes. Altering the pitching spring stiffness affects weight transfer and pitch, which can change mid-corner balance. Evaluate on track and adjust oil or piston size to refine the effect.

Is this spring suitable for both YR-X12 and YR-X1219 without modification?

The spring is listed as compatible with both YR-X12 and YR-X1219 pitching dampers and should fit directly when installed correctly. Confirm clearance and operation after assembly before competitive use.
