If you are not expert, you do not know how to check if if real sensor or fake sensor, since the fake one also
can assemble and the car will not leakage to come down.
To help the customers to get to know about it and we do not mind to open the secretes.
We are willing to teach our customers to to get to know if the car suspension shock with real sensor or fake sensor

Firstly, after assembling, observe whether the car will automatically rise or fall according to the road conditions. 
For example, when parking, the body will automatically come lower, and when starting, the body will rise along 
with the shock absorber. 
But if you find that the body has always remained at a level, and it will not change according to the road conditions, 
then I am sorry, you may bought products with fake shock absorbers.

Secondly, if you are a repair shop or do not mind damaging the product, you can cut the product to view it, 
the difference was shown as following picture.
