In a vehicle with a frame and ground-engaging wheels suspended therefrom by a suspension having, on each side of the vehicle, a bracket rigidly secured to the frame; a trailing arm pivotably mounted to the bracket and having two sets of openings, each set aligned transversely of the trailing arm; an air spring rigidly connected to and between the frame and the trailing arm; and a bushing extending between each set of aligned openings and positioned within the trailing arm. An axle is rigidly connected to each trailing arm by an axle bracket. Each axle bracket comprises a wrapper rigidly secured to the axle; two plates rigidly secured to the wrapper, each plate having two apertures aligned with the two sets of openings; a shock mounting bracket rigidly secured to one of the plates; and four gussets rigidly secured to and between the plates and the wrapper to add rigidity to the axle bracket to aid in withstanding torsional and lateral forces exerted thereon incidental to the operation of the vehicle. At least one of the four gussets is curved to resiliently yield in response to torsional forces between the wrapper and the connecting plate to which it is attached. Each axle bracket is secured to each trailing arm by two pins, each pin extends through each aligned set of apertures and openings and a bushing. A shock absorber is connected to and between each of the shock mounting brackets and the frame.
