The XRAY 308354-O Aluminum Shock Cap Nut is intended to simplify assembly and oil control on T4 ULP shock absorbers. Its vent hole allows surplus shock fluid to escape while the cap is tightened, which helps set the correct internal oil level and promotes steady damping behaviour.
These cap nuts are produced from durable aluminium and finished in orange anodize for corrosion resistance and visual clarity. Precisely cut internal features hold the silicone membrane in place to help prevent leaks and maintain shock integrity. Expect slight colour differences due to the anodizing procedure.
These caps make oil metering and reassembly quicker and more reliable, helpful when testing different damping setups. They suit modelers who need predictable shock response with minimal fuss during service intervals.
