1. A vehicle stabilizer bar comprising:
a first housing configured to be fixed to a first side-bar, the first housing defining a first portion of a first coupling;
a second housing configured to be fixed to a second side-bar, the second housing disposed within the first housing;
a clutch piston disposed within the first 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 first housing, and ii) provides for axial movement between the clutch piston and the first housing; and
a first portion of a second coupling;
a clutch ring fixed to the second housing, the clutch ring defining a second portion of the second coupling, the second portion of the second coupling configured to cooperate with the first portion of the second coupling to selectively torsionally couple the first housing to the second housing; and
a screw assembly having:
a screw coupled to the clutch piston; and
a nut disposed within the second housing and drivably connected to the screw; and
an actuator configured to rotate the nut so that the screw moves axially 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.
