A step bumper is a type of automotive trim that extends from the front of a vehicle, providing additional protection and design enhancement. It typically sits above the standard bumper and provides an extra level of safety by adding height to the front end of the car, which can help prevent damage in low-speed collisions or parking lot dings. Step bumpers are often used on trucks, SUVs, and other larger vehicles that may be more prone to such incidents. They also add aesthetic appeal by providing an extra design element to the front of the vehicle.
