Why does the Volkswagen Touran's body become higher after replacing the rear shock absorbers?

The Volkswagen Touran's body becomes higher after replacing the rear shock absorbers because the installed shock absorbers are of an incorrect model. Definition of Shock Absorbers: Shock absorbers can quickly attenuate the vibrations of the frame and body, improving the smoothness and comfort of the car's ride. The device installed in the car's suspension system is called a shock absorber. Working Principle of Shock Absorbers: The principle involves filling a cylinder, which has small holes and a piston, with pressurized oil. When the spring vibrates, the oil is forced to flow through the small holes, thereby providing damping. The size of the hole's diameter determines the extent of the damping effect. If the hole diameter is smaller, the damping is stronger, resulting in higher car stability; conversely, the ride comfort is improved.
After replacing the rear shock absorbers on my Touran recently, the car body suddenly became nearly 2 centimeters higher. I consulted the familiar garage owner about this. He said this is a common occurrence - with prolonged use, the springs on old shock absorbers fatigue and sag, and installing brand new components restores the factory height. I checked the repair order and confirmed that both the shock absorbers and matching springs were replaced simultaneously. Now when driving over speed bumps, the car feels more stable, and the gap between the tires and wheel arches has become more even. However, the owner reminded me to observe for a week - if the height continues to change, I'll need to go back for suspension alignment adjustments, otherwise it might affect tire wear. I think this principle is similar to needing an adaptation period when wearing new shoes - old components will inevitably deform and compress after prolonged use.
