  • Since 1977, Iowa-based Dee Zee(R) has sought to create products and accessories for trucks and SUVs with class-leading levels of style, quality, and longevity. Their success and growth in the marketplace has always been fueled by listening to what customers want, then building the things competitors did not offer. Dee Zee believes that it is extremely important to be environmentally aware and views efficient manufacturing to minimize pollution and waste as a corporate responsibility. That philosophy goes hand in hand with fundamental beliefs that a product which effectively resists corrosion represents a better value for the customer - giving it a longer useful lifespan instead of becoming more junk in a landfill. Our website is proud to offer the Dee Zee product you've seen on this page as well as the company's complete lineup of running boards, grille guards, tool boxes, bed protectors, mud flaps, liquid transfer tanks, cargo carriers, and much more.

They are designed to mimic the style popular original equipment side bars and running boards, featuring two professional finish options, large non-skid step pads and tapered end caps. This particular pair of 6 in. ovals is made with 304 stainless steel, meaning they are high in nickel content to be truly resistant to rust and corrosion. For a lasting shine and a bright accent on your vehicle, they are given a highly polished, mirror-like finish. They are also available in semi-gloss black powder-coated aluminum. To protect the interior of the tubes, all 6 in. oval sides are equipped with hard ABS plastic end caps.

For a sure step every time you climb into your vehicle, ARIES 6 in. ovals are equipped with extra-wide step pads. The step pads are made from tough polypropylene and provide a generous 5 in. width. The large, flat surface offers comfortable footing and has a textured surface to prevent slipping, even when wet. The polypropylene construction makes the step pads durable and crack-resistant for long-lasting use. ARIES 6 in. oval side bars are also made for easy, no-drill installation. The boards themselves feature a track system for versatile application, and they mount using vehicle-specific brackets for a custom fit. The mounting brackets are made from high-strength carbon steel and use pre-existing holes to eliminate drilling during the installation process (NOTE: Mounting brackets for these side bars are sold separately.

The angular edges provide a clear-cut, uncompromising accent for the look of todays trucks. Made from 5-1/2 in. wide, eight-sided, extruded aluminum tubing, AdvantEDGE side bars are strong, lightweight and impervious to rust, offering a solid step that is built to face the elements and outlast them. They also come with die-cast aluminum end caps and a stamped aluminum tread. The aluminum treads provide a long-lasting, non-skid stepping surface that will not crack or fade in the sun. ARIES AdvantEDGE side bars are also marked for their easy, custom-fit installation. They feature the ARIES VersaTrac mounting system with brackets that are made from powder-coated steel and built for specific vehicles (NOTE: VersaTrac mounting brackets are sold separately; see application information to determine which brackets and side bars fit your vehicle). The high-strength steel brackets mount using pre-existing holes, and the side bars attach to the brackets with heavy-duty hardware and a full-length channel. The VersaTrac mounting system makes installation simple and customizable, allowing the side bars to be swapped out at any time with other side steps or running boards that feature the VersaTrac system. Setting yourself apart is simple with the ARIES AdvantEDGE series. In addition to our AdvantEDGE side bars, we also offer the AdvantEDGE bull bar and AdvantEDGE headache rack, featuring the same all-aluminum construction and eight-sided tube profile. For a fully customized look to match your pickup, AdvantEDGE side bars are available in two finish options, including carbide black powder coat or chrome powder coat.
