O-ring for adjuster nut on L.F Pro Shock

Specifically produced to work with L.F Pro Shock damper assemblies, this O-ring fits beneath the adjuster nut to help maintain the internal seal and correct adjuster positioning. It is an RC component and not intended for use on road-going vehicles.

The component keeps the adjuster nut seated and protects the damper seal from oil loss and contamination, which supports consistent damping adjustments and more predictable setup results.

Installation is easy: remove the adjuster nut, place the O-ring in its seat on the adjuster shaft or shock cap as appropriate, then reattach the nut ensuring the ring is not trapped or twisted. Check routinely for signs of wear and swap it out if the seal is failing.

Tips for longevity: apply a thin film of silicone grease compatible with your shock oil to ease fitting, avoid over-tightening the adjuster nut which can deform the O-ring, and perform a brief test run to confirm there are no leaks.
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 the main benefit of this O-ring?

Its primary benefit is preserving the damper seal at the adjuster nut, reducing oil seepage and helping maintain stable adjuster travel for reliable setup changes.

How should I inspect the O-ring during maintenance?

During routine damper servicing, look for nicks, compression marks, or hardening; any of these indicate the O-ring should be replaced to ensure proper sealing.

Does this affect tuning feel?

Yes. A correctly seated O-ring stabilises adjuster movement so preload and damping changes are more repeatable, which improves tuning precision.
