A pressure-balanced shock absorber has an outer tube, an inflatable base, a piston tube, a valve adjusting rod, a piston base, an inner tube, and an adjusting resilient element. The inflatable base has a valve passage and a first valve core. The first valve core selectively seals the valve passage. The piston tube communicates with the valve passage. The valve adjusting rod is movably mounted in the valve passage of the inflatable base and the valve tube. The piston base is connected to the piston tube and has a piston passage. A second valve core selectively seals the piston passage. The inner tube is mounted around the piston tube. The piston base divides the inner tube into a first air chamber and a second air chamber. The adjusting resilient element is disposed in the piston tube to achieve the effect of inflating two air chambers.
