ARB Summit step section has more than just one function. One of the functions it serves is to help protect the side of the car. The jutting out construction helps in impeding the approach of any object or body that can cause harm to the car. But that is a secondary function that you can get out of it. The main function it serves is to help the passengers get in the cabin and reach the roof easily. The step features a tread plate that can help you get a good grip. The step can prevent you from slipping when reaching for the roof or entering the cabin.
