The XRAY 308354-O Aluminum Shock Cap Nut provides a simple way to control oil volume when assembling T4 ULP shocks. These precisely machined aluminium caps include a small vent hole so excess oil is expelled during installation, helping the shock reach the intended fill for repeatable damping.
Made from robust aluminium, the cap nuts balance strength with low weight. The orange anodized surface protects against corrosion while giving a neat finish. Inside, fine machining secures the silicone membrane for a reliable seal and reduces the chance of leaks. Colour shades may differ slightly between batches.
Whether you are adjusting damping for a race or weekend running, these cap nuts make it easier to achieve consistent shock behaviour. They are a straightforward upgrade for hobbyists who value precise oil control and clean assembly.
