Step into your truck like you mean it with ARIES Big Step 4" round side bars. When it comes to your truck, Jeep or SUV, don't waste time with accessories that miss the mark. You need solid parts with plenty of attitude. ARIES Big Step nerf bars are made to be bigger, bolder and longer-lasting, featuring a powder-coated aluminum construction. These aluminum nerf bars are 40% lighter than steel and offer excellent strength and rigidity. They are also highly impervious to corrosion and are coated in a textured black finish to protect against scratching and scuffs. Some of the features that make the ARIES 4" side bar a bold accessory are its mandrel-bent ends and extra-large step pads. The ends offer a unique look compared to capped ends and give the side bars a more contoured appearance. The custom step pads provide a generous width for more comfortable footing, and the textured pads are made from polypropylene so they will not crack or get slippery when wet. ARIES Big Step 4" round nerf bars are compatible with a variety of trucks, Jeeps and SUVs. The vehicle-specific mounting brackets are designed for a custom fit on each unique application, and they allow you to use factory mounting holes for a no-drill installation. This set of custom side bars fits specific years of the Chevrolet Silverado and GMC Sierra 1500, 2500 HD or 3500 HD crew cab (see application info to verify fitment). ARIES Big Step 4" round side bars are also designed to go hand-in-hand with the ARIES Big Horn bull bar, giving you a complete look for your custom ride.
