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 for full customization: polished stainless steel and black powder coat carbon steel. This set of side bars is constructed from high-strength carbon steel for a solid step, and they feature a dual-layer E-coat and semi-gloss black powder coat finish for excellent protection against scratching, chipping and peeling. 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. 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 Chevrolet Silverado and GMC Sierra 1500, 2500 HD or 3500 HD crew cab (see application info to verify fitment).
