A common problem: The convertible top cylinders of your Porsche 911 / 996 / 997 are no longer sealed when opening or closing the convertible top.

It is recommended that both cylinders be replaced at the same time, as if one begins to leak, the other is very likely to leak soon as well.
Important: The convertible-top cylinders must be sent to us for repair. Please ship them only with tracking-no.!
