An elastomeric isolator has an elastomeric body which defines a void extending into the elastomeric body from one side and a void extending into the elastomeric body from the opposite side. One member for attaching the elastomeric body to a component is located inside of the two voids and another member for attaching the elastomeric body to a component is located outside of the two voids. The two voids overlap a specified distance to determine the stresses and stiffness for the isolator.
