A lift axle parallelogram suspension system. In a described embodiment, a suspension system for a vehicle having a generally longitudinally extending frame includes an axle assembly and upper and lower trailing arms. One end of each of the upper and lower arms is attached to the frame at a pivot connection, and an opposite end of the arm is attached to the axle assembly at another pivot connection. Each of the arms is angled laterally outward from the frame as the arm extends from the frame pivot connection to the axle assembly pivot connection.
