Why does the car body become higher after replacing the original shock absorber?

[DamianAnn]

After replacing the original shock absorber, the car body may become higher due to the spring not fully settling with the shock absorber. It usually returns to normal height after driving for a period of time. The following is relevant information about car shock absorbers: 1. Definition: Shock absorbers are used to suppress the oscillation when the spring rebounds after absorbing shocks and impacts from the road surface. They are widely used in cars to accelerate the attenuation of vibrations in the frame and body, thereby improving the driving comfort of the car. 2. Principle: Most shock absorbers used in car suspension systems are hydraulic shock absorbers. Their working principle is that when there is relative movement between the frame (or body) and the frame due to vibration, the piston inside the shock absorber moves up and down, causing the oil in the shock absorber chamber to repeatedly flow from one chamber to another through different pores.
