Pitching damper components overview

This Yokomo YX-40CY kit includes the cylinder, AJ adjustment nut and replacement O-rings used in the pitching damper assemblies of 1/12 on-road models. It is intended as an aftermarket service kit for changing worn parts and tweaking pitching preload on compatible chassis.

The cylinder is treated with a Kashima-style hard anodized layer to reduce piston-to-wall friction during stroke, supporting a consistent damping response. The item targets component replacement and small setup changes rather than full damper refurbishment.

Assembly advice: replace degraded O-rings and confirm sealing after fitting, set the AJ nut to achieve the required spring preload, and confirm free piston travel before running. Routine inspections after several outings will reveal O-ring compression or surface wear early.

Compatible Models

  • 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.

What is replaced when I use the YX-40CY kit

The kit replaces the cylinder body, supplies an AJ adjustment nut and fresh O-rings to restore sealing and adjust preload.

How often should O-rings be checked or changed

Inspect O-rings after a few sessions for compression or hardening; replace when sealing degrades or after visible wear to maintain consistent damping.

Best practice for setting AJ nut preload

Adjust the AJ nut gradually while testing piston movement and ride characteristics, then run a few laps and recheck seal and travel for consistency.
