A suspension system for a machine is disclosed. The suspension system may have a front torsion axle assembly with a first arm connected at a first end to a first shaft, and a first axle connected to a second end of the first arm. The suspension system may also have a rear torsion axle assembly with a second arm connected at a first end to a second shaft, and a second axle connected to a second end of the second arm. The suspension system may further have a frame connected to an end of the first shaft and an end of the second shaft. The second ends of the first and second arms are oriented within common angular quadrants defined by a coordinate system having an axis passing through the first ends of the first and second arms and aligned with a travel direction of the machine.
