Damper down-stop O-ring

This small rubber O-ring serves as a down stop in RC damper and shock assemblies, delivering a controlled cushion at the end of compression travel. It is designed for scale RC use where an O-ring style stop limits or softens piston or shaft bottoming.

Fitting is simple on most shock designs: slide the O-ring onto the shock shaft or place it on the lower seating area according to your damper layout, then cycle the suspension to set the desired down-stop feel. Confirm shaft diameter and clearance before final assembly since designs vary.

When tuning, the O-ring alters bottoming sensation and enables fine adjustments to rebound and compression response when combined with spring and oil changes. Replace the ring if the rubber shows cracking, flattening, or permanent deformation to maintain consistent performance.

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 does the down stop O-ring affect shock feel?

It cushions full compression and reduces harsh bottoming, giving a smoother transition at the end of travel and finer feedback during tuning.

When should I replace the O-ring?

Replace it when you see cracking, flat spots, or hardening; worn rings alter damping and lead to inconsistent results.
