Powerful, definitive and uncompromising as a mountain ridge, ARIES RidgeStep running boards are made for the truck owner 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 inserts. The inserts move along the channel to fit your vehicle, and the mounting hardware provides a secure attachment. The boards are made in four base lengths, including 53", 75", 85" and 91", and they are designed for vehicle-specific application (NOTE: VersaTrac mounting brackets are sold separately; see the application information to determine which brackets and boards fit 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 vehicle for a professional finish. RidgeStep running boards come with a unique textured black powder coat finish to only withstand rust but also to hide minor scratches and grime. From the cattle ranch of the arid desert plains to the forgotten forest trails of the frozen tundra, the job doesnt wait for those who lag behind. Rise to the challenge and master the job with ARIES RidgeStep running boards.
