A system for centering a relatively movable member relative to a relatively fixed member includes telescoped inner and outer cap tubes with opposed closed ends adapted to be connected to the fixed and movable members. A strut tube assembly within the cap tubes includes a gas spring unit that is compressed by a force transfer tube assembly when the system is compressed or extended. Resilient bumpers smooth the force transition near the centered position. A set screw permits adjustment of the system to have preload or no preload or to have free play at the centered position. The system is easily adapted to specific requirements by selection of the gas spring unit and the material of the bumpers and by adjustment of the set screw.
