When you start and end your day turning the ignition of your truck, unreliable footing just is not an option. You need a step that can bear weight with ease, provide comfortable footing and look good doing it. ARIES 4" oval side bars are sleek, strong and custom-fitted to be a highly functional extension of your truck. ARIES 4" oval side bars are made with strong 4" elliptical tubing and are available in two different finish options to allow you full customization: polished stainless steel and black powder coat carbon steel. This set of side bars is constructed from 304 stainless steel, meaning high nickel content to be truly stainless. They easily resist rust and corrosion and feature a highly polished finish that is made to last. Something that sets the ARIES 4" oval side bar apart from all others is its blended end caps and OE-style bends. Rather than capping our side bars with a plastic cap, we offer a blended end cap for a smooth, finished appearance. We also equip the ends with a special 20-degree bend and original equipment styling to perfectly contour to your vehicle. ARIES 4" oval side bars are fitted with raised step pads to provide a wide stepping surface. The polypropylene construction will not crack over time, and because it has a textured grip, the surface is highly resistant to slips and skids, even when wet. To add an extra element of class to our oval sides, we also fit each one with a stainless steel insignia bearing the ARIES name. Installation of ARIES 4" oval side bars is quick and easy with custom-fitted mounting brackets and no drilling necessary. These nerf bars fit select model years of the Ford F-150, F-150 Lightning, F-250 Super Duty, F-350 Super Duty, F-450 Super Duty and F-550 Super Duty (see application info to verify fitment).
