Chrome rocker arm panels are made exclusively from premium 3M acrylic foam and 304 stainless steel adhesive that provides a "mirror-like" finish and helps protect against weathering and stone damage.
In trucks and SUVs, the rocker panel is often used as a stepping stone for easy access to the vehicle. Since vans and SUVs are relatively tall, this extra step facilitates the process of entering the vehicle. To support the weight of the occupants over the life of the vehicle, the rocker panels of these larger models are larger and stronger.
