Bumpers are one of the most essential auto parts. They fulfill both an aesthetic and practical function. They are also important safety features. Bumpers are made of heavy sheet metal and are mounted on the front and rear of the car. Bumpers flex and take specific shapes to absorb and generate momentum during a collision. In the event of a collision, the bumper absorbs some of the impact, reducing damage to the car and its occupants. It also protects the front of the car by diverting all of the car’s momentum toward the object it has collided with. The bumper is mounted on the car chassis with special shock absorbers. These shock absorbers usually have springs. In low speed collisions, this allows the bumper to compress and then extend back to its original position. All bumpers are designed to absorb impact energy. They do this through a series of valves and air chambers.
Some car bumpers have hydraulic chambers. In the event of a collision, the absorption unit allows the passage of air and/or hydraulic fluid through small openings. Forcing air/liquid through the valve openings absorbs the energy of the collision. The bumper’s job is to minimize damage, primarily to vehicle occupants and the vehicle itself. US law requires cars to pass special crash tests at various speeds.
To pass, the car’s damage level during the crash must be below a specified dollar level. This protects the consumer and is very important in keeping the cost of auto insurance to a minimum. Bumpers are sometimes built with “crumple zones” built in. crumple zones are designed to absorb impact; They will flex on impact. As the metal flexes, the action of the bent metal converts the car’s kinetic energy into heat. Kinetic energy is the energy an object possesses while it is in motion.
All GM cars are equipped with capable bumpers that help protect the vehicle from serious damage in the event of a collision. However, like all auto parts, bumpers will eventually become damaged or defective due to accidents, wear, and corrosion. Typically, such damage will weaken the bumper’s ability to absorb the impact of the collision. Therefore, it is necessary to replace the old and damaged bumpers with a new one. Replacement GM bumpers can be purchased at auto parts dealers around the world. However, to be sure of quality and durability, only buy from a trustworthy and trustworthy auto parts store with an established reputation.
