There is a real fluidamper either here or moparts.
There are only two dampers I'd buy. That's the FD or the Innovaters West damper.
I will never ever run a damper with rubber in it. I don't care who runs one. Rubber is a piss poor long term damper.
I am personally running a chicom FD knock off on my engine. I have a FD on the shelf for the W2 engine.
