A hydraulic shock absorber having an outer tube which is closed at one end and open at the other end. An inner tube, having a plurality of metering orifices, and having a closed inner end and an open end, is mounted in the outer tube with its closed end against the closed end of the outer tube. A meter tube, having a plurality of metering openings, is rotatably mounted above the inner tube. The inner tube is retained in its longitudinal operative position by the meter tube, a rotatable retainer member, and a wave washer. A locking pin retains the inner tube against rotation. The inner tube, meter tube, and the rotatable retainer member are all assembled into the outer tube through the open end of the outer tube, and they are retained in the outer tube by a retainer member. A meter tube adjusting ring is rotatably mounted on the outer tube, and it is connected to the meter tube for adjusting the position of the metering holes in the meter tube relative to the metering orifices in the inner tube. The ends of the shock absorber are threaded for operative mounting in a threaded mounting flange which is adapted to be secured to a machine or other support member.
