The invention provides a frequency self-adaptive shock absorber, a shock absorber piston, a chassis system and a vehicle, and aims to solve the problems that the shock absorption effect of the vehicle is poor, and particularly, the vibration of the vehicle is obvious when the vehicle is subjected to high-frequency vibration so as to improve the driving and riding comfort of the vehicle. The frequency self-adaptive shock absorber comprises a cylinder barrel, an oil storage cavity and a piston and further comprises a buffering cavity formed in the piston, a valve assembly dividing the buffering cavity into a left buffering cavity and a right buffering cavity is arranged in the buffering cavity, one end of the valve assembly is in sealing fit with the buffering cavity, and the other end of the valve assembly is also in sealing fit with the buffering cavity. The buffer cavities are provided with oil outlet holes formed between the two ends of the valve assembly, the valve assembly can move along the buffer cavities, the valve assembly is provided with a first reset elastic piece enabling the valve assembly to reset, and the pressed area, located on one side of the left buffer cavity, of the valve assembly is smaller than or equal to the pressed area, located on one side of the right buffer cavity, of the valve assembly. And a sliding block which is in sliding and sealing fit with the right buffer cavity is arranged in the right buffer cavity.
