An air spring assembly for a vehicle having a damper body which is decoupled from a piston, allowing the damper to rotate freely without inducing torsion into the piston. The air spring assembly includes a damper body, and a decoupling mechanism connected to the damper body, where a portion of the decoupling mechanism surrounds the damper body. A piston is connected to the decoupling mechanism such that the decoupling mechanism allows for rotation of the damper body relative to the piston, preventing torsion from being transferred from the damper body to the piston. The decoupling mechanism also includes a rotatable machine element, such as a bearing, surrounding the damper body, and the bearing is adjacent the cup portion such that the rotatable machine element facilitates relative rotation between the damper body and the spring cup portion to limit torsion applied to the piston from the damper body.
