When servicing your XRAY RC model, keeping the shock caps sealed is essential. The XRAY 970120 O-Ring set, sized 12x1mm, is intended for upper cap sealing to help prevent oil leakage and preserve shock performance during running.
These O-rings are made to suit XRAY XB4 shock assemblies and provide a close fit to improve sealing. Whether you are dialing in damping for a track day or weekend bashing, fresh O-rings help maintain predictable shock behaviour by stopping oil bleed.
Fitting the XRAY 970120 rings is simple: remove the old seals from the upper cap, clean mating surfaces, then seat the new 12x1mm O-rings evenly. Inspect for nicks and replace if you spot wear to avoid premature leaks and to extend shock life.
