ARIES – 3 Inch Round Side Bars (Part No.204045)

3 Inch Round Side Bars

from

$164.99
ARIES 3″ side bars are more than a fancy decal for your truck, Jeep or SUV. They are a confident first step on each new adventure. These 3″ nerf bars are constructed from strong carbon steel for superior rigidity, and they feature a sleek semi-gloss black powder coat finish. For an added edge, each nerf bar also goes through an E-coat process, before receiving its black powder coat, to strengthen and protect the final finish against peeling, chipping and scratching. ARIES 3″ round side bars are also available in polished stainless steel or semi-gloss black powder-coated steel. All ARIES 3″ nerf bars come with heavy-duty steel brackets and non-skid step pads. The mounting brackets are strong and custom-designed for specific makes and models to allow the side bars to contour to the lines of your vehicle. They offer easy installation and the strength necessary to provide sound footing. These particular custom nerf bars fit specific years of the Chevy Silverado 1500, 2500 HD, 2500 HD Classic or 3500 HD and GMC Sierra 1500, 2500 HD or 3500 HD (see application info to verify fitment). ARIES 3″ round side bars also come with non-skid step pads made of tough polypropylene. These step pads feature a textured pattern for enhanced safety, and they cover a wide portion of the tubes for a more comfortable step.

Product Features:
  • Unique bends to contour to the body of the vehicle
  • Custom, non-skid step pads for safe entry and exit
  • 3″ diameter, heavy-wall tube design

ARIES – 4 Inch Oval Side Bars (Part No.S224045)

4 Inch Oval Side Bars

from

$209.99
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. 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. 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 (NOTE: This set of side bars is compatible with DEF tank models). These nerf bars fit select model years of the Chevrolet Silverado and GMC Sierra 1500, 2500 HD, 2500 HD Classic, 3500 HD and 3500 Classic (see application info to verify fitment).

6 Inch Oval Side Bars

from

$308.99
For solid footing, a comfortable step and a bold look for your truck, ARIES 6″ oval side bars are a step up. They are designed to mimic the style of 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″ ovals is made with aluminum alloy to be strong and lightweight. Aluminum construction makes them completely impervious to rust, and for an extra layer of corrosion protection, they come with a durable semi-gloss black powder coat finish. They are also available in polished 304 stainless steel. To protect the interior of the tubes, all 6″ oval sides are equipped with hard ABS plastic end caps. The end caps come pre-attached to the tubes and feature a tapered design, lending to the overall OE look of the side bars and providing a professional finishing touch on your truck or SUV. For a sure step every time you climb into your vehicle, ARIES 6″ ovals are equipped with extra-wide step pads. The step pads are made from tough polypropylene and provide a generous 5″ 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″ 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. See the application information to find which brackets and side bars fit your vehicle).

ARIES – 4 Inch Oval Side Bars (Part No.S224045-2)

4 Inch Oval Side Bars

from

$300.99
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. 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 (NOTE: This set of side bars is compatible with DEF tank models). These nerf bars fit select model years of the Chevrolet Silverado and GMC Sierra 1500, 2500 HD, 2500 HD Classic, 3500 HD and 3500 Classic (see application info to verify fitment).

Product Features:
  • 20-degree bends to contour to the body of the vehicle
  • Seamless, welded end caps for a superior, finished look
  • Raised, custom, non-skid step pads for safe, comfortable entry and exit
  • 304 stainless steel construction to be strong and truly rust-resistant
  • Mirror-like polished stainless steel finish for a bright, clean accent
  • Brushed stainless steel ARIES insignia on each step
  • Elliptical, 4″ wide, heavy-wall tube design
  • No-drill, vehicle-specific application for a custom fit
  • Heavy-duty steel mounting brackets (compatible with DEF tank models)
