Warranty: Limited Lifetime Warranty (One-Year Parts)
Finish: POLISHED STAINLESS
Material: Blank
Color: Stainless
Side Component Type: Board and Bracket
ARIES 3" side bars add a custom look and dependable footing to your truck, Jeep or SUV. They feature a classic style, a strong design and non-skid step pads. ARIES nerf bars are all made vehicle-specific for a custom, no-drill fit, and they are available in multiple finish options. This set of nerf bars is constructed from 304 stainless steel with a polished finish. Our 304 stainless steel is a true stainless with high nickel content, offering better corrosion resistance and a long-lasting finish. The polish is a triple application, resulting in a mirror-like shine to complement your vehicle. ARIES 3" round side bars also come with high-strength steel brackets and non-skid step pads. The mounting brackets -- as well as the side bars and step pads -- are custom-designed for specific makes and models to allow the nerf bars to contour to the lines of your vehicle. This ensures easy, no-drill installation and the strength necessary to provide solid footing. This particular set of custom nerf bars fits specific years of the Chevy Suburban (see application info to verify fitment). ARIES 3" round side bars also come with non-skid step pads made of polypropylene. These wide, custom-positioned step pads feature a textured pattern and cover a wide portion of the tubes to be more comfortable and high-traction, even in wet conditions.

The installation procedure requires working from underneath the truck to access the factory body mount bolts and rear leaf spring hangers. The manual does not specify whether lifting equipment is required, but access to the underside of the vehicle is essential. Consult a qualified installer or the manufacturer for specific equipment recommendations.
Installation begins on the passenger side front, then proceeds to the passenger side rear, then repeats the same sequence on the driver side. For each side: (1) attach the front mount bracket to the factory body mount bolt from underneath, (2) attach the front support bracket with 10mm × 30mm hex bolts, (3) attach the rear mount bracket to the rear leaf spring hanger using the factory nut, (4) attach the rear brace bracket to the frame and rear mount bracket with 12mm bolts, (5) position and attach the side bar to the mounting brackets with 12mm × 50mm hex bolts, (6) level and adjust the side bar, then tighten all hardware.
Yes. The front mount bracket is attached to the underside of the vehicle's front body mount using the factory body mount bolt. Do not remove the rubber bushings. The bolt is removed only to allow the bracket to be positioned, then reused to secure the bracket.
Yes. The rear mount bracket is slid over the leaf spring bracket and secured using the factory nut that was removed from the rear leaf spring hanger. This factory nut is reused to hold the rear mount bracket in place.
Do not tighten fasteners as you install them. The manual specifies to 'snug but do not tighten' the front mount bracket, front support bracket, rear mount bracket, rear brace bracket, and side bar bolts during installation. Only after the side bar has been leveled and adjusted should all hardware be tightened.
The front support bracket is attached using 2 × 10mm × 30mm hex head bolts with corresponding washers (10mm flat washers and 10mm lock washers).
The rear brace bracket is secured to the frame and rear mount bracket using 2 × 12mm hex bolts, 2 × 12mm flat washers, 2 × 12mm lock washers, and 2 × 12mm hex nuts.
The side bar is attached to the mounting brackets using 2 × 12mm × 50mm hex head bolts, 2 × 12mm lock washers, and 2 × 12mm flat washers.
Do not remove the rubber bushings when removing the factory body mount bolt. The rubber bushings must remain in place.
Wax the product after installing to protect the finish. Regular waxing is recommended to add a protective layer. Do not use any polish or wax containing abrasives, as these can damage the finish. For stainless steel, aluminum polish may be used to polish small scratches and scuffs, and mild soap may be used to clean. For gloss black finishes, use only mild soap to clean.
Perform periodic inspections to ensure that all hardware is secure and tight. The manual does not specify the inspection interval or a detailed checklist beyond verifying hardware security.
