If the shock absorber is too hard, it will seriously affect the driving comfort, making the vehicle's filtering effect on road bumps worse during driving, and passengers can obviously feel more vibrations. Here are some methods to improve the shock absorber and their actual effects.

Replacing the shock absorber oil is a common method. The viscosity of the shock absorber oil has a great influence on the shock absorption effect. If the shock absorber oil viscosity is too high, it will cause the shock absorber to be too hard. We can choose a shock absorber oil with a slightly lower viscosity for replacement. This method is relatively low in cost, generally around a few hundred yuan, and the operation is not complicated. Some experienced car owners can even replace it by themselves. However, its effect may be relatively limited. It is not obvious for the improvement of the hardness caused by the quality problem of the shock absorber itself. It can only alleviate the situation of too hard shock absorption to a certain extent, so that the vibration of the vehicle will be slightly reduced when passing through some small bumps.

Modifying the shock absorber is also a feasible way. There are many modified shock absorbers on the market that are specially designed to improve shock absorption performance. They are optimized in design and material. For example, some adjustable shock absorbers allow car owners to adjust the hardness of the shock absorber according to their needs and different road conditions. This method is quite effective and can fundamentally change the performance of the shock absorber. However, it is expensive. The price of a set of modified shock absorbers may be several thousand yuan or even tens of thousands of yuan, and the installation requires professional technology and equipment; otherwise, it may affect the safety of the vehicle.

Adjusting the tire pressure should not be ignored either. Too high tire pressure will reduce the contact area between the tire and the ground, and the buffering performance will deteriorate, which will indirectly lead to a more obvious feeling of shock absorption. Adjusting the tire pressure to the standard pressure range specified by the vehicle manufacturer can improve the shock absorption effect to a certain extent.

This is a simple and extremely low-cost method that only requires a pressure gauge and an air pump to operate. It can make the vehicle more stable when driving, and the problem of shock absorption will be improved, especially on flat roads.
