The first front suspension mount connects to a vehicle frame and to a cab. The second front suspension mount connects to the vehicle frame and to the cab. The rear suspension system has a first angled linking arm, a second angled linking arm, and a spring assembly. The first angled linking arm connects to the vehicle frame and to the cab. The second angled linking arm connects to the vehicle frame and to the cab. The spring assembly connects to the cab and to the vehicle frame. The first angled linking arm and the second angled linking arm are disposed to form a generally V-shape.

Abstract: A suspension assembly for a vehicle has at least two leaf spring assemblies providing at least two load paths. The leaf springs are vertically separated and mount to a shackle assembly which is mounted to the chassis. The shackle assembly has at least two shackles and may have a load transfer assembly. The leaf springs also attach to a spring hanger opposite the shackle assembly. The load transfer assembly has inner and outer load transfer plates to which the leaf springs and the shackles fasten to form a four-bar linkage.
