Description

Technical Field

[0001] This utility model relates to the technical field of automotive shock absorber accessories, and more specifically, to a guide for automotive shock absorbers. Background Technology

[0002] The guide for automotive shock absorbers is an important component. During use, the upper end of the guide is fixed to the upper cylinder of the shock absorber, and the lower end of the guide is fixed to the lower cylinder.
