A disconnectible stabilizer bar assembly for a vehicle having first and second stabilizer bar halves, a housing fixed to an end portion of each stabilizer bar half, so as to align the two halves. The housing containing a stator with magnetic coil, a rotor with exterior magnets and threaded onto a hollow screw, with the stator selectively rotating the rotor and the rotation translated into axial movement of the screw. The screw having meshing means on an interior surface and an end face, the interior meshing means meshed with an exterior meshing means on one of the stabilizer bar halves, and the end face meshing means selectively coupled and decoupled with aligned mashing means on the other of the stabilizer bar halves.
