Bumpers are one of the most essential auto parts. They
serve 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 are bent and formed into specific shapes in
order to absorb and deliver momentum during a collision.
In the event of a collision, the bumper absorbs some of
the impact, which decreases damage to the car and its
occupants. It also protects the front of the car by
diverting all of the car's momentum to the object with
which it has collided. The bumper is mounted to the car's
chassis with special impact absorbers. These shock
absorbers are often spring loaded. In slow speed
collisions, this allows the bumper to compress, and then
extend back to its original position. All bumpers are
designed to absorb the energy of the impact. 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 air and/or
hydraulic fluid to pass through small openings. Forcing
the air/fluid through the valve openings absorbs the
energy from the collision. The bumper's job is to minimize
damage, primarily to the occupants of the vehicle and to
the vehicle itself. US law requires cars to pass special
crash tests at various speeds.
In order to pass, the car's damage level during the
crash must be below a specific dollar level. This protects
the consumer and is very important for keeping the cost of
automobile insurance to a minimum. Sometimes bumpers are
constructed with built-in "crumple zones."
Crumple zones are designed to absorb impact; they will
flex on impact. As the metal flexes, the action of the
bending metal converts the kinetic energy of the car into
heat. Kinetic energy is the energy an object possesses
while it is in motion.
GM automobiles are all equipped with capable bumpers
that help protect the vehicle from serious damages in the
event of a collision. However, like all auto parts,
bumpers will eventually get damaged or defective due to
accidents, wear and tear and corrosion. Usually such
damages will weaken the bumper's ability to absorb the
shock of collision. Thus, it is a necessity to replace old
and damaged bumpers with a new one. Replacement GM Bumpers
can be purchased from auto parts dealers everywhere.
However, to be sure of quality and durability, purchase
only from a reliable and trustworthy auto parts store with
an established reputation.
