Body kits are aftermarket parts that replace the front bumper, side skirts and rear bumper of a car or truck. Body kits are usually damaged by hitting an object on the road or by getting too close to a curb, causing rips or nicks. In other cases a bolt hole can be ripped and made larger so that the bolt no longer holds the kit to the car. You can fix the damage to make the body kit functional and stylish again.
