These components are aftermarket or original equipment manufacturer (OEM) accessories designed for the specified model year of the full-size pickup truck. They are typically constructed from materials such as steel, aluminum, or durable polymers, and are mounted along the vehicle’s rocker panels, beneath the doors. Functionally, they serve as an intermediate stepping surface between the ground and the truck’s cabin.
The installation of these accessories provides enhanced accessibility, particularly for occupants with limited mobility. They contribute to vehicle aesthetics, offering a customized appearance. Historically, such accessories gained popularity with the increasing ride height of trucks and SUVs, addressing the practical need for easier ingress and egress. They can also offer a degree of protection to the vehicle’s lower body panels from road debris and minor impacts.
