The suspension system includes a first dampener connected at a 5 first location between the first body and second body and a second dampener connected at a second location between the first body and second body. The first dampener is operatively connected to the second dampener such that actuation of the first or the second dampener in one direction causes the other of the first or the second dampener to have an increased dampening effect in 10 the opposite direction. The invention is particularly applicable when used as a yaw suspension system for an articulated boom arm.
