A four-point wishbone-shaped linkage is disclosed for use in a suspension system. The wishbone-shaped linkage includes a base and two limbs extending away from the base creating a large mouth open area between the limbs and base. The base includes a bar and bushing assembly extending laterally therethrough. Also disclosed are suspension systems incorporating the four-point wishbone-shaped linkage. The suspension system connects an axle to a vehicle chassis having a first frame member and a second frame member extending longitudinally on opposite sides of the chassis, respectively. The first and second frame hangers are mounted to the first and second frame member, respectively, a cross member connects the first and second frame hangers and the wishbone-shaped linkage is pivotally connected to the axle seats mounted to the axle and to the cross member. The suspension system also can include air springs, shock absorbers and torque rods.
