A suspension system for a vehicle having a frame includes a first interface member configured to be positioned on a first lateral side of the frame and a second interface member configured to be positioned on an opposing second lateral side of the frame. The first interface member and the second interface member are positioned along a common central axis. The suspension system also includes a first swing arm coupled to the first interface member and configured to rotate about the common central axis, a second swing arm coupled to the second interface member and configured to rotate about the common central axis, and a sway bar coupled to the first interface member and the second interface member.
