An axle/suspension system for a heavy-duty vehicle, in which the vehicle has a frame that includes a pair of hangers. The axle/suspension system is attached to the hangers, and includes an axle and a pair of suspension assemblies. Each of the suspension assemblies includes an air spring and at least one spring member. The spring member includes a first attachment portion and a second attachment portion. The first attachment portion is generally rigidly connected to the hanger via a clamped connection, and the second attachment portion is operatively connected to the axle. The spring member, connected in this manner, reduces or eliminates dock walk when a cargo transfer vehicle enters the heavy-duty vehicle, and also reduces or eliminates rebound when the cargo transfer vehicle exits the vehicle. The spring member is also capable of being tuned to a predetermined stiffness that is sufficient to control heavy-duty vehicle roll forces.
