Adjuster Nut O-Ring for L.F Pro Shock Compatible Dampers - YOKYS7A by Yokomo  [YOKYS7A]

Sealing O-ring for the adjuster nut

Designed for use with L.F Pro Shock damper assemblies, this O-ring seats under the adjuster nut to preserve the internal seal and maintain correct adjuster alignment. It is a model-scale damper spare, not suitable for road vehicles.

The part helps keep the adjuster nut stable and reduces oil leakage and contamination at the adjuster interface, which supports consistent preload and damping adjustments during setup and track testing.

To fit: remove the adjuster nut, position the O-ring on the adjuster shaft or in its seat according to your shock's layout, then replace the nut while ensuring the ring sits evenly and is not pinched. Inspect the ring regularly for wear and replace when sealing performance drops.

Service suggestions: avoid using greases that react with shock oil, tighten the adjuster nut only to the manufacturer's recommended feel to prevent deformation, and verify the seal after a short session to ensure no seepage is present.
