A suspension system for liftable steerable axles has at least one steering knuckle; at least one pistonless bellows air spring actuator (ie., damper air spring); and a steering axle structure that has, at each end, a kingpin housing boss, a kingpin fixed into the kingpin boss, and a pair of steering knuckles that rotate around the kingpin and are supported by the kingpin housing; wherein the steering knuckles are connected at the bottom of each other side to side by a tie rod assembly that respond to each others rotational inputs; and further having the damper air spring being connected to the steering knuckle so that, given a supplied pneumatic air force, the damper air spring stabilizes and dampens the steering road inputs when in motion.
