Powerful, definitive and uncompromising as a mountain ridge, ARIES RidgeStep running boards are made for those who gets it done, day after day. With their solid, all-steel construction, non-skid treads and tough powder coat finish, RidgeStep running boards are made to finish the job. Installation of these running boards is easy and secure because they use the ARIES VersaTrac mounting system. The underside of each board is equipped with a channel that accepts a set of heavy-duty bracket insert s. The inserts move along the channel to fit your truck, and the mounting hardware provides a secure attachment. These running boards are designed to fit specific years of the Ford F-150 (NOTE: This set of running boards includes vehicle-specific VersaTrac mounting brackets. See the application information to verify compatibility with your vehicle). ARIES RidgeStep running boards are not only made for easier installation, but they are also built to face the harsh elements of the commercial job. They feature high-strength, solid steel construction for a step that can keep up with those steel-toe boots, and they are completely without plastic parts, meaning they will not crack or fade over time. Their stamped, all-steel tread offers a 6-1/2" wide, non-skid surface that will never wear down no matter how many times you climb in and out of your truck. The end caps are also made from steel and are welded to contour to the body of your truck for a professional finish. RidgeStep running boards come with a unique E-coat and textured black powder coat finish to not only withstand rust but also to hide minor scratches and grime.
