Finish: SEMI-GLOSS BLACK POWDER COAT

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 Suburban (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.

The Curt 204039 is designed for 1973–1991 Chevy Suburban models only. Verify your vehicle year and model before purchasing.
Yes, the Curt 204039 and 204039-2 are designed specifically for 1973–1991 Chevy Suburban models. Confirm your vehicle year falls within this range before installation.
The manual requires access to the underside of the vehicle to locate and remove body mount bolts and rear leaf spring hangers. A lift or jack is likely necessary, but the manual does not explicitly state this requirement. Consult the manufacturer or a professional installer to confirm.
Install the passenger side first, then repeat the same steps on the driver side. For each side: (1) attach the front mounting bracket to the factory body mount using the factory bolt, snug but do not tighten; (2) attach the front support bracket using two 10mm × 30mm hex bolts with washers, snug but do not tighten; (3) slide the rear mounting bracket over the leaf spring bracket and secure with the factory nut, snug but do not tighten; (4) attach the rear support bracket to the frame and rear mount bracket using two 12mm bolts, washers, lock washers, and nuts, snug but do not tighten; (5) position the side bar onto the mounting brackets and attach using two 12mm × 50mm bolts with lock washers and flat washers, snug but do not tighten; (6) level and adjust the side bar, then tighten all hardware.
Do not tighten fasteners as you install them. The manual instructs you to snug (hand-tighten) all bolts and nuts during the initial assembly steps. Only after the side bar is positioned and leveled should you tighten all hardware. This allows for proper alignment and adjustment before final tightening.
From underneath the vehicle, locate the factory body mount bolt that runs upward through and mounts into the floorboard. Remove this bolt but do not remove the rubber bushing. Attach the front mounting bracket to the underside of the vehicle's front body mount using the factory body mount bolt. Snug but do not tighten at this time.
Attach the front support bracket using two 10mm × 30mm hex head bolts with corresponding washers. Snug but do not tighten at this time. Figure 1 in the manual shows the front mount bracket and brace bracket attached.
Locate the rear nut of the rear leaf spring hanger (shown in Figures 2 and 2A). Remove only the nut, not the bolt. Slide the rear mounting bracket over the leaf spring bracket and secure it using the factory nut. Snug but do not tighten at this time.
Slide the rear support bracket up to the inner cross member bracket from the frame. Secure it to both the frame and the rear mount bracket using two 12mm hex bolts, two 12mm flat washers, two 12mm lock washers, and two 12mm hex nuts. Snug but do not tighten at this time.
Carefully position the side bar onto the mounting brackets. Attach it using two 12mm × 50mm hex head bolts, two 12mm lock washers, and two 12mm flat washers. Snug but do not tighten at this time. After positioning and leveling the side bar, tighten all hardware.
Snug means to hand-tighten the fastener until it is snug (firm) but not fully tightened. This allows you to position and level the side bar before final tightening. Once the side bar is leveled and adjusted, you then tighten all hardware fully.
The manual instructs you to level and adjust the side bar after it is attached to all mounting brackets but before final tightening. The specific method for leveling is not detailed in the manual. Use a level tool to ensure the bar is properly aligned, then tighten all hardware.
Do not remove the rubber bushings when detaching the factory body mount bolts. Preserve these bushings as they are part of the vehicle's suspension system. After installation, perform periodic inspections to ensure all hardware remains secure and tight.
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 may 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.
After installation, perform periodic inspections to ensure that all hardware is secure and tight. The manual does not specify the frequency of these inspections or what specific checks to perform beyond verifying hardware tightness.
No. When you remove the factory body mount bolt, do not remove the rubber bushings. Keep them in place and reuse the factory bolt to attach the front mounting bracket.
Yes. The installation reuses the factory body mount bolt to attach the front mounting bracket and the factory rear leaf spring nut to secure the rear mounting bracket.
No. The installation uses existing factory mounting points (body mounts and leaf spring hangers) and does not require drilling, cutting, welding, or permanent modifications to the vehicle.
Wax the bars after installation and regularly thereafter. Do not use abrasive polish or wax. For stainless steel, aluminum polish may be used on small scratches; for gloss black, use mild soap only.
