The shock absorber is just one part of the shock absorber assembly. The shock absorber assembly includes:
Front shock absorber: Top rubber, bearing jacket, cushion cotton, dust cover, nut, etc.
Rear shock absorber: Top rubber, cushion cotton, dust cover, nut, etc.
The shock absorber is mainly used to suppress the shock and the impact from the road surface when the spring rebounds after absorbing the shock. When passing on uneven roads, although the shock-absorbing spring can filter the vibration of the road, the spring itself will reciprocate, and the shock absorber is used to suppress the jump of this spring. If the shock absorber is too soft, the body will jump up and down, and if the shock absorber is too hard, it will bring too much resistance and prevent the spring from working properly. In the process of modifying the suspension system, the hard shock absorber should be matched with the hard spring, and the hardness of the spring is closely related to the weight of the car. Therefore, heavier cars generally use harder shock absorbers.
