Can You Bring Car Shock Absorbers and Struts on Planes?

Most shock absorbers and struts contain compressed gases, which are classified as dangerous goods by most airline regulators. Some have banned them in hand and checked luggage altogether. Others allow compressed gas cylinders only if they don’t contain flammable gases, and only on certain devices, like avalanche backpacks, life vests, and medical devices. Furthermore, they’re usually allowed only in 50ml containers or less. Shock manufacturers usually don’t specify how much gas is inside, so the security agents can’t confirm if they’re allowed or not.

Usually, gas-powered shocks and struts contain nitrogen gas, which is non-flammable. So theoretically, gas shock absorbers could be allowed on some flights in Australia and the UK. But because manufacturers don’t specify how much gas is inside, and only less than 50ml is allowed, they can’t be brought on planes.

Because oil shock absorbers use automotive oil for shock absorption, they can’t be brought in checked and hand luggage. Auto car parts that contain residue of gasoline or oil are banned in hand and checked luggage.

Theoretically, if you open the seal for shocks or struts, and get rid of all the gases and oils inside, they should be allowed on planes. However, you have to clean all the residue throughout because it can’t have even tiny traces of oil. You should also be able to clearly show the security agent that it doesn’t contain any compressed gases or oils. And finally, you should remember that the final decision always rests on the security officer, so they might still prohibit you from bringing shocks on planes. Generally, we would advise transporting shocks with shipping couriers instead.
