Review on ZRM Vibration Compressor Isolator Silentblock by Rickey Ortega

I actually got 8 of these and used 4 for my air compressor pump and the other 4 for the electric motor. They are well done. However, I had to remove 4 under the engine because they bent too much. I could not get enough belt tension between the motor and pump. The fasteners are bent. The ones under the pump were fine.
