Component Description and Fit

The YOKYX40S assembly is supplied by Yokomo as a replacement shaft and piston set for YRX-12 pitching dampers. Fitting this set replaces worn parts to recover consistent stroke behavior and dependable damper feedback during acceleration and braking on circuit surfaces.

Routine installation follows standard shock maintenance: extract the pitching damper from the chassis, take apart the damper per the service guide, exchange the shaft and piston, then reassemble using your seals and damper oil. Ensure cleanliness and check free piston travel prior to reinstalling the damper.

When assessing performance impact, note that this part modifies internal flow rather than spring characteristics. Swapping to a fresh shaft and piston helps maintain steady mid-stroke damping; match piston hole count and oil grade to retain your tuned baseline handling.

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.
The part is listed for YRX-12 pitching dampers; check the shaft diameter and piston dimensions on your damper to confirm compatibility before fitting.
Replacement interval depends on use and track conditions; inspect for wear, scoring, or oil leakage and replace when damping becomes inconsistent. Regular checks extend service life.
Yes. Installing a fresh shaft and piston restores consistent piston movement and helps prevent variable damping caused by worn components.
