Adjuster nut O-ring for L.F Pro shocks

This is a small-scale RC damper component designed for use with L.F Pro Shock assemblies, serving as the O-ring beneath the adjuster nut to maintain seal and positioning. It is an RC-scale accessory intended for shock maintenance and tuning, not for real vehicles.

Functionally the part keeps the adjuster nut seated and helps preserve the damper seal so oil leakage and contamination are reduced. In tuning contexts this stabilises adjuster travel so repeatable preload and damping adjustments are easier to achieve during setup.

Installation is simple: remove the adjuster nut, fit the O-ring onto the adjuster shaft or seating as required by your shock design, then reinstall the nut ensuring the ring is not pinched. Inspect the ring for cuts or flattening during routine maintenance and replace if seal integrity is compromised.

Practical tips: use only light silicone grease compatible with shock oil to ease installation and avoid swelling, avoid over-tightening the adjuster nut which can deform the O-ring, and check the fit after a few test runs to confirm there are no leaks.
