A vibration isolator includes a housing forming an internal cavity, an elastomeric diaphragm within the internal cavity, the elastomeric diaphragm combining with a first end of the housing to form an air spring within the internal cavity, a mechanical spring in series with the air spring within the internal cavity; a mount in series with the mechanical spring opposite the air spring, an annular elastomeric stopper between a second end of the housing and the mount, wherein the mount and the annular elastomeric stopper combine to seal the second end of the housing to form a chamber within the internal cavity between the elastomeric diaphragm and the second end of the housing, and a plate seated on the mount within the chamber.
