Are the bumpers at 4S stores all genuine?

[Stewart]

Under normal circumstances, the bumpers replaced at 4S stores are genuine parts. Here is a detailed introduction about car bumpers: 1. Overview: A car bumper is a safety device that absorbs and mitigates external impacts, protecting the front and rear of the vehicle body. In the past, front and rear bumpers were made of steel plates pressed into channel steel, with a relatively large gap between them and the vehicle body, which was less aesthetically pleasing. 2. Composition: Generally, a plastic car bumper consists of three parts: the outer panel, buffer material, and crossbeam. The outer panel and buffer material are made of plastic, while the crossbeam is formed by cold-rolled thin plates pressed into a U-shaped channel; the outer panel and buffer material are attached to the crossbeam. 3. Function: To absorb and mitigate external impacts on the vehicle, protecting the body. It has the ability to reduce injuries to passengers when the vehicle is subjected to high-speed collisions.
