Yokomo YOKR12-18O Shock O Ring Pack for YOKOMO R12 (6pcs)  [YOKR12-18O]

Shock O rings for YOKOMO R12

This Yokomo YOKR12-18O pack supplies six shock O rings intended for use on YOKOMO R12 dampers as an RC-scale accessory. The set focuses on basic damper service items used to maintain seal integrity and prevent oil leakage in hobby shock assemblies.

Installation is straightforward: remove the damper cap and piston rod, replace the worn O ring on the shaft or cap where the original sits, then reassemble using the correct shock oil and recommended piston orientation. Keep parts and work area clean to avoid introducing debris that can score the O ring.

From a tuning perspective O rings do not alter damping characteristics directly, but maintaining intact seals ensures consistent damping by preventing oil loss and air ingress. Regular inspection and timely replacement keep damper performance repeatable during setup and testing.
