These are aftermarket or factory-installed accessories designed to mount along the lower sides of a specific model year of a full-size pickup truck produced by a Japanese automotive manufacturer. These additions typically provide a more convenient and secure point of entry and exit from the vehicle’s elevated cabin.
Their presence significantly enhances safety and accessibility, particularly for individuals with limited mobility or when the truck is frequently utilized in challenging terrains. Historically, such accessories have evolved from simple running boards to more sophisticated designs incorporating features like integrated lighting and non-slip surfaces. Their durability and compatibility with the vehicles frame are key considerations.
