Abstract
A parallelogram lift axle suspension system includes an in-line lift bellows located between and vertically aligned with a pair of upper and lower control arms so as to provide bi-directional expansion and contraction of the lift bellows for raising and lowering the suspension while increasing the space available between the longitudinal frame rails enabling use of the suspension in certain vehicles by avoiding interference with other vehicle components of the vehicle located in this space.
