Vibration isolators (100) are provided that include a shaft (102), a first bushing (124), a second bushing (164), a first outer annular member (126), a second outer angular member (166), a first elastomeric member (128), a second elastomeric member (168), and a shim (107). The first elastomeric member (128) is adapted to provide a first stiffness for damping a first vibration, and the second elastomeric member (168) is adapted to provide a second stiffness for damping a second vibration, the second stiffness being greater than the first stiffness.
