If the stiffness of the car shock absorber is too high, it will affect the shock absorption capacity of the suspension system. The driver will feel stronger bumps and vibrations, which will reduce driving comfort. Especially when driving on uneven roads, the vehicle will be more bumpy, and the occupants will feel uncomfortable or even fatigued.

The overly stiff shock absorber may also limit the tire's ability to grip the road. The tire's grip is critical for the vehicle's grip and traction. Overly stiff shock absorbers will prevent the wheels from fully gripping the ground, reducing the contact area with the ground, and thereby reducing the vehicle's grip and traction. In special road conditions, such as wet roads or sharp turns, overly stiff shock absorbers can cause the vehicle to lose control, affecting handling stability and safety.

When choosing car shock absorbers, it is necessary to comprehensively consider the comfort and handling performance of the vehicle. The appropriate shock absorber stiffness can balance the driving comfort and shock absorption capacity of the suspension system when driving on smooth roads. Overly stiff shock absorbers will not only reduce driving comfort but also have a negative impact on the vehicle's grip and traction, and even lead to loss of control.

When purchasing a vehicle or replacing shock absorbers, consumers should consult professionals to understand the appropriate shock absorber stiffness for their vehicle model and ensure that they choose the right shock absorber to balance comfort and handling. Automakers should also focus on shock absorber stiffness adjustment during the R&D process to provide better driving comfort and safety.
