1. A stabilizer bar assembly for a suspension system of a vehicle, the stabilizer bar assembly comprising:
a first bar configured to be coupled to the suspension system proximate to a first wheel;
a second bar adjacent to the first bar; and
a coupling assembly at an interface between the first bar and the second bar, the coupling assembly including:
a magnetorheological material in contact with both the first bar and the second bar, the magnetorheological material configured to transform from a fluid state to a viscoelastic solid state when subject to a magnetic field; and
a magnet configured to apply the magnetic field to the magnetorheological material, in the viscoelastic solid state the magnetorheological material resists relative movement between the first bar and the second bar.
