1. A vehicle stabilizer bar comprising:
a housing configured to be fixed to a first side-bar, the housing defining a first portion of a first coupling;
a hydraulic power unit disposed within the housing;
a clutch piston disposed within the housing, the clutch piston defining:
a second portion of the first coupling configured to cooperate with the first portion of the first coupling, such that the first coupling: i) torsionally couples the clutch piston to the housing, and ii) provides for axial movement between the clutch piston and the housing; and
a first portion of a second coupling;
a clutch ring configured to be fixed to a second side-bar, the clutch ring defining a second portion of the second coupling, the second coupling configured to cooperate with the first portion of the first coupling to selectively torsionally couple the clutch piston to the clutch ring; and
the hydraulic power unit is configured to selectively move the clutch piston from a first connected position, in which the clutch piston is torsionally coupled to the clutch ring, to a second disconnected position, in which the clutch piston is torsionally uncoupled from the clutch ring.
