PINNUO specialize in air suspension industry since 2003. We helped people fix their air suspension by replace it with a new one in our workshop. It will cost about $400-800 per strut, some customers ask if we can only replace the damaged part instead of whole air strut.
To make it possible, we try many times and finally found a way to repair air suspension shock and save money. We need a special machine that can shrink the steel rings and lock the rubber bladder and new rubber bladder and steel rings and etc.
Now we had developed the special machine and a series of replace parts for air suspension shock absorber. With these device, you can repair an air suspension shock easily and only cost $10-30.
