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

After replacing the original shock absorber, the car body may become higher due to the spring not fully settling with the shock absorber. Generally, it will return to normal height after driving for a period of time. Below is some relevant information about car shock absorbers: Definition: Shock absorbers are used to dampen the oscillations from the spring's rebound after absorbing shocks and impacts from the road surface. They are widely used in automobiles to accelerate the attenuation of vibrations in the frame and body, thereby improving the vehicle's ride comfort. Principle: Most shock absorbers used in automotive suspension systems are hydraulic shock absorbers. Their working principle is that when relative motion occurs between the frame (or body) and the axle due to vibrations, 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 orifices.

As someone with considerable driving experience, I've personally encountered the issue of increased vehicle height after replacing factory shock absorbers. Worn-out shock absorbers cause springs or damping components to deform over time, slightly lowering the car body. When new OEM parts are installed, the vehicle returns to its standard height. If technicians don't fully compress and secure the springs during installation, it may temporarily raise the vehicle height. After driving for a day or two, the suspension will gradually settle back to its familiar level. While increased height doesn't affect safety, be cautious if the car feels unstable or wobbly during turns - this could indicate improper suspension installation or aged springs. I recommend promptly visiting a professional repair shop to check spring length and shock absorber compatibility, preventing future tire wear or handling issues. Regular suspension system inspections during maintenance can prevent problems, as these details significantly impact vehicle longevity.

As a car enthusiast, it's common to see the body rise after replacing factory shock absorbers. Over years of use, old shocks loosen up, causing the car to naturally sag; the new components with full elasticity restore the vehicle to its original factory height. Improper spring compression during installation or loosely tightened bolts can also temporarily raise the body—don't panic, take a few short drives, and it usually self-adjusts back. A higher ride height actually has benefits, like improved ground clearance, but excessive height affects driving fun and handling precision, especially at high speeds. Check if the wheel and chassis gaps are abnormal; if the difference is significant or there are unusual noises, visit a mechanic immediately to verify the shock absorber model and compatibility with the original springs. Maintaining a regular shock replacement habit extends the chassis lifespan and reduces future issues.

I've repaired many cars, and the reason why the body becomes higher after replacing the original shock absorbers is mainly due to the wear of old components. The new shock absorbers restore their elasticity, lifting the body; during installation, if the springs are not pre-compressed or the bushings are aged, it can also trigger this phenomenon. A slight height change is normal and will decrease after driving a few dozen kilometers. However, if it is noticeably higher or the driving is unstable, the suspension system needs to be checked: see if the shock absorbers match the vehicle model and the condition of the springs. Body height issues directly affect braking distance and steering safety and cannot be ignored. Quickly take the car to a workshop for evaluation to prevent incorrect installation or other hidden faults. Pay attention to the replacement cycle of shock absorbers during regular maintenance, generally suitable for replacement every five years or 80,000 kilometers.
