The invention relates to a gas pressure shock absorber for vehicle chassis having a damper tube (1) and a piston rod (3) which supports a working piston (2) and is disposed in a reciprocally moveable manner in the damper tube (1), wherein a first partial volume (1a) of the inner space of the damper tube (1) can be filled with a damping fluid and a second partial volume (1b) of the inner space of the damper tube (1) can be filled with a gas, and wherein the gas pressure shock absorber has a device for regulating the vehicle level, which is actuated by the introduction of a gas under pressure into the inner space of the damper tube (1). In order to be able to both raise and also lower the vehicle level as often as desired it is proposed that the device for regulating the vehicle level has a separate vessel (4), the inner space of which is divided by a displaceable separating piston (5) into a first partial chamber (6) filled with damping fluid and a second partial chamber (7) which can be filled with gas, wherein the first partial chamber (6) is connected to the first partial volume (1a) of the damper tube (1), and the second partial chamber (7) is attached to a source of compressed gas. The invention also relates to a spring strut with a vehicle support spring made from steel and a gas pressure shock absorber in accordance with the invention.
