Video Transcript for Aries Round Nerf Bars Review

Speaker 1: Today we're going to be taking a look at Aries line of 3" diameter round nerf bars.These 3" tube steps are going to make your vehicle look better, and they're going to make it easier to get in and out.These are particularly useful for small children getting in and out of the vehicle, or for other people that have a hard time getting in and out of the vehicle. If you have a lifted vehicle they can make it easier for anybody to get in.This is going to be a durable carbon steel, 3" diameter tube step. It's going to run from the front door, all the way to the back. So the both the front and back doors are going to make it easier for all your passengers.There will be foot pads located on each rail. They're made of a durable polypropylene and they've got ridges on them to help increase traction while getting in and out of your vehicle.Each tube step is going to be custom fit for your vehicle. It's going to come with a unique rail and brackets that will bolt right up and make a nice easy installation.Depending on your application you may have weld nuts you can bolt directly into, or there may be some existing holes for the hardware.You can get these in a polished stainless steel, or a black powder coat finish like the one we have here.Our customer Earl says, "Easy to install and made my daughters truck look great.

Plus it made it easier for her to climb into her truck." Here are some pictures from other customers as well.Unlike simple steps, tube steps provide a larger area for your feet. They also blend in more with the vehicle over steps, which tend to provide a more rugged look. The rounded curved look also sets them apart from flat and straight running boards. Running boards have a larger step area. Of the three options, it's a matter of personal style as to which you prefer.

If you have decided to go with tube steps, Aries and Westin make similar options. It may just come down to price and style as to which you prefer.And that completes our look at Aries line of 3" diameter round nerf bars.

Bars are still sitting in the box because the bracketing didn't fit my truck, instructions don't match my rocker panels, ordered correct kit and verified.

I am sorry that you have the wrong Nerf Bars for your application. I have sent your information over to our customer service department for them to assist you in getting the correct bars for your vehicle.

great service and fast shipping

2019 Chevrolet Silverado 1500 LD

The instructions are not correct! In step two of the instructions there are no threaded holes on the inside body panel for the m8 hex bolts to thread into! I had to furnish my own bolts and feed them through the assigned hole in order to install the bars!

I reached out to my contact at Aries about the issue you had on your 2019 1500. He said that they have seen this issue every now and then on GM vehicles. They have not been able to figure out a rhyme or reason for which trucks are missing the threaded holes on the body panel. They have a kit available if your truck is missing the threaded s in the body panel. You can reach out to Aries at 1-877-287-8634 if you need this kit.

2017 Chevrolet Silverado 1500

The price was good and they look great on my 2017 double cab 1500! Took about an hour to install, however the installation were not exact for my application but I figured it out. Shipping was fast.

  • Brackets For Step Bars on 2019 Chevy Silverado Crew Cab
    The # AABRKT-204046 bracket kit you mentioned would be compatible with a 2019 Chevy Silverado 1500LD (previous year body style), 2500 and 3500 Double Cab (which is what Chevy calls their Crew Cab). This being said, I can't say if thosee brackets would be compatible with the OEM Chevy bars you have, as Aries hasn't tested their compatibility. For something that's sure to fit, your best bet would be to get new bars/brackets/hardware like # AA204046-2 in stainless or # AA204046 in black...

  • Do Aries Nerf Bars # AA204046 Fit 2019 Chevy Silverado 1500 LD and Require Drilling
    Yes the Aries nerf bars # AA204046 that you referenced are a fit for your 2019 Chevy Silverado 1500 LD as long as it's a double cab. There is no drilling required to install these also.

  • Are There Replacement Pads Available for a Set of Nerf Bars on an Unknown Brand
    I have an option for you but unfortunately nerf bars and their parts are specific to the vehicle and the bars themselves. From the pictures you were able to provide me I can see that we do not have that brand of crossbar and therefore I am not going to have replacement parts for it. From the pictures I can see that your current pad has a 4 peg attachment. All of the 4 peg pads we have do not line up with the same measurements or peg pattern that yours has. You may be better off replacing...

  • Aries Nerf Bar Fitment on a 2006 Nissan Frontier King Cab
    The Aries Round Nerf Bars # AA204046-2 you referenced use the replacement mounting bracket kit # AABRKT-204046 but this kit is designed for a 2007-2019 GM truck. Since you have a 2006 Nissan Frontier you need a different set of nerf bars and mounting hardware for them to fit properly. If you want the polished stainless steel style like what you mentioned having then you need part # AA209019-2, otherwise we have part # AA209019 which is a semi-gloss black powder coat instead. Both of these...

  • How to Remove Old Rubber Step Pad on Aries 3 Inch Nerf Bar
    To replace the rubber step pad on the 3" Aries Nerf Bars for your 2019 GMC Sierra 2500 Double Cab, like what we see with part # AA204046-2, you'll need the replacement step pad # AA2090139. This installs with metal clip inserts that the nibs on the step pad secure to. You'll likely have to rip off the top of the pad and then work to get the metal clips off. I saw a review where someone had to eventually take a drill bit to them as they can be difficult (see attached photo).

  • Nerf Bars to Fit 2016 GMC Sierra 3500 Crew Cab
    We do have nerf bars for your 2016 GMC Sierra 3500 Crew Cab but # AA204046 is only for the double cab. Instead you need # AA204045 which are for the Crew Cab. I've linked a video of them being installed on a Chevy 2500 which will be the same process. They also come in stainless steel, # AA204045-2.

  • How Does Westin 23-1685 Nerf Bar Attach to 2010 Chevy Silverado
    The Westin # 23-1685 step bars do indeed attach to the vehicle via the existing body mount bolts. If you'd prefer a similar product that attaches to the inboard surface of the rocker panels, the Aries # AA204046-2 which is compatible with the Silverado extended cab like the Westin # 23-1685 would be a good choice. We don't offer a step bar kit that mounts to the vehicle frame.
