A vehicle body suspension system comprising a piston-cylinder assembly provided between a vehicle wheel and a vehicle body. The piston, which is disposed within the cylinder connected to the wheel, and the piston rod coupled to the piston, are each formed with an oil channel extending axially therethrough. The end of the piston rod which is remote from the piston is connected to the vehicle body by means of an annular elastic member arranged around such end of the piston rod. An oil chamber having a variable volume is provided, and has part of its peripheral wall formed by part of the elastic member. A first damper arrangement is provided between the oil chamber and the oil channel for action during contraction of the system, and a second damper arrangement is provided in the piston for action during elongation of the system. An auxiliary vehicle body suspension spring is provided between the cylinder and the piston rod. A vehicle body height adjusting piston may be provided between the piston rod and the elastic member, and secured to the end of the piston rod remote from the main piston. The first damper arrangement is provided with an automatic damping adjustment arrangement.
