A torsional vibration damper hub for a vehicle clutch includes a first row of springs extending substantially in the clutch rotating direction and disposed in openings formed in first inner annular plate and first pair of outer annular plates; second row of springs extending substantially in the clutch rotating direction and disposed in openings formed in the second inner annular plate and the second pair of outer annular plates; the first and second row of the springs being arranged on same radius from center of rotation of the clutch; the springs in the first row of springs arranged in one first axial level are axially overlapping the springs in the second row of springs arranged in a second axial level with the purpose to decrease a total axial length of the clutch. In an alternative embodiment the damper hub is substantially identical to a dual damper hub in conventional twin-plate clutches.
