The luxury sedan you love has two of them on its body -- one up front and one installed on the rear. They both help absorb impact force, which can reduce the effects of an accident-- namely, injuries (to you, your passengers, and even pedestrians) and vehicle damage.

What They're Made of

Stock bumpers are more often than not comprised of acrylonitrile butadiene styrene (commonly called ABS plastic), but others can be made of stronger materials, like polypropylene. Some are reinforced with protective aluminum or steel bars, while others have enhancements such as longer overhangs. The commonest bumpers on the road today, though, are original, designed right off the factory line for everyday driving. Smaller ones can even improve gas mileage slightly.

When to Replace Them

The simple answer: when they get dinged or dented, crack, break completely, or otherwise wear out. It's usually okay to drive with a little bumper damage, assuming the bumper's secure. However, if either or both are at risk of coming off (or they've detached already), your car may be both unsafe and illegal to drive. Luckily, replacing them is easy. You can order new ones for the project right here online, at our auto parts store.
