  • Black
  • 4 Inch Wide
  • Steel
  • Westin
  • Oval
  • Gloss Finish

The curved ends on these black powder coated step bars give your vehicle a streamlined look. Footpad areas are recessed, rather than cut out, preserving the strength of the steel and providing a solid, rustproof step into your truck.


Features:

  • Cab-length, oval nerf bars make it easy to get into and out of your vehicle
    • Greater stability than narrower round bars
  • Curved ends of step bars give a finished, street-style look
  • Non-slip step pads sit in recessed tube areas instead of cutouts
    • No holes in tubing means maximum strength and durability with no internal corrosion
    • Sturdy polymer plastic construction resists UV rays, fading, and cracking
  • Mild steel with black powder coat finish is long-lasting and rust resistant
  • Mandrel bending at corners eliminates creases in tubing
  • Custom fit for your vehicle
  • Quick and easy bolt-on installation with included hardware
    • No drilling required


Specs:

  • Tubing width: 4"
  • Step pad width: 4"
  • Step pad quantity: 2 per bar
  • Quantity: 2 nerf bars
  • 3-Year warranty


The step pad areas in Westin's Platinum Series oval nerf bars are indented instead of cut out, maintaining the structural integrity of the steel tubing and preventing internal corrosion. 90-Degree mandrel bending at the corners means that there are no creases in the bars. This minimizes the chances of chips and rust at the bends and makes for sleeker, better-looking step bars.


U-Style Tube Steps

As shown in the image above, these step bars have a U-style tubing, which ensures that each bar conforms perfectly to your vehicle. Installation is quick and simple - just bolt the mounting brackets to existing holes in your truck's frame. No drilling is required.

As others have noted, the instructions are not terribly robust, but once I got oriented, I was able to move along quite quickly. Either the rear brackets were mis-labeled, or the 2017 frame is slightly different. Swapping the parts side to side made the holes line up the way they should. Install took less than 90 minutes. I'm very pleased with the fit, finish, and the always fast service from e-Trailer.

The package arrived early in the day because the UPS driver didn't want to work around it in his truck all day. That meant I could install them right away. Nice!



by:

Easy install using the video, had all the parts needed, very solid nerf bars.

Fit and fastener alignment was good. Easy installation. Pleased with product quality.

Installed on 2018 Tacoma sport. Unfortunately, it arrived with a ding in the passenger side bar. It was very disappointing, but by the time I saw it (I should have thoroughly checked both bars before starting install), I had already installed the driver’s side. I said, to heck with it and didn’t bother with a return.

It was an extremely easy install with quick delivery and overall, they look great. Now, I don’t have to haul myself up into my Tacoma. The step inserts are basically a heavy duty plastic. I figure if they are slippery, I can spray them with a propert texturing coating. At some point, I’ll probably also texture/ mat spray the bars themselves since they’re gloss finish.



by:

The step/bars look good. Install wasn't tough but Westin's instructions are poor- I just figured it out on my own.

While the packaging looked stout, 3 of the 4 open bar ends were bent in, like someone dropped the box on both ends. I did a decent job of banging the dents out and installed them. Those ends aren't seen once installed. Someone needs to look at a better way to protect them during shipping.

Overall I'm just satisfied with the product.



by:

These Western tube steps fit my 2013 Silverado Reg. cab perfect, even with the DEF tank.
Installed quickly, and look great.
Thanks Chris W. at etrailer.com



by:

These Nerf Bars are just what my truck needed! They look awesome and were a cinch to install. Customer service is also great and I can’t say enough about the ETRAILER web site. Will definitely use them again!!



by:

Excellent product. Looks great on my vintage 2004 Silverado. Easy installation once I CAREFULLY removed the body mount bolts. Only suggestion would be to include the torque specs for the body mounting bolts for reinstallation.



by:

Very well built. Replaced a pair of Westin nerf bars that were 20 years old. Very easy to install. Well worth the money. I have always liked Westin products. Etrailers always delivers no matter what you need!



by:

It just was delivered today. I want be able to write a review until I get them installed.
Price was good and shipping was very fast.



by:

I am very happy with these running boards. They are just the right width for easy use. They are solid, and they installed easily on my Tundra. I would buy these again if I had it to do over.



by:

After 1 year I have nothing bad to say about these bars they do as I wanted getting everyone in and out of my truck with ease. It was more for protecting the seats from sliding in and out not to break down the seat cushion and to protect the cloth seats from tears, but after sitting in the truck at a shopping center it does something I never thought of, other people hit the bars with car doors not my truck, they still look like new



by:

High quality, easy installation and good fit.



by:

Product is as described. Installation was not complicated and easily done by one person. Fit perfectly on my 2018 Ram 3500. Install tip: duct tape is your friend when you fumble one of the nut holders into the frame. That will slow you down. :-)



by:

Look nice. Easy installation. The instructions were a little vague.



by:

Excellent product and great value. Installation of the brackets and bars were simple and did everything myself. Bars are lightweight, but very sturdy and robust. The plastic steps are rather heavy duty and not loose. The 4 inch diameter is the perfect size for my needs: doesn't stick out far like most running boards and not too small to where my feet wouldn't get good purchase on a step.
The bars weren't has curved inward under the body as advertised. The pictures show these bar curve in a lot, but the bars I got only had a slight bend at the ends. If you've got front mudguards, the bar will touch the guard; it wont actually put pressure or bend the mudguard, but just touch it. Despite the inaccuracy of the pictures, it turned out well as the mudguard would interfere with a fully curved in bar. It still looks sleek. There really isn't much of a gap between the bars and body, the bar isn't low so my ground clearance isn't compromised.
Overall, great bars that look great and function well.



by:

Great steps for a great price!

Installed the Westin 21-3610 4 in oval SS step bars on my 2015 Jeep GC Summit.Hemi California edition - perfect fit. See photos. After 2014 Jeep uses 12 mil plastic stickers instead of the rubber plug caps for the oval cutouts as called out in the Westin install procedure - use a small wood chisel to remove the cover stickers carefully.

  • Recommended Westin Platinum Series Nerf Bars for 2019 Ram 1500 Classic Quad Cab
    I have a solution for you, but the Westin Platinum Series Oval Nerf Bars # 21-3565 are not a confirmed fit on your 2019 Ram 1500 Classic Quad cab-they are instead designed for the Crew cab models. Instead, I recommend the Westin Platinum Series Oval Nerf Bars # 21-3555 which are the same nerf bars you were looking at, only designed to fit on the Quad cab versions of the 2019 Ram 1500 Classic.

  • Replacement Mounting Hardware for Westin Oval Nerf Bars for 2020 Ram 1500 Classic Quad Cab
    I may have a solution for you, but the # 23-231PK are designed for round nerf bars that fit on 2002-2009 Ram trucks and not a 2020 Ram 1500. If you've got Westin brand steps on your 2020 Ram 1500 Classic like the Westin Platinum Series Oval Nerf Bars - 4" - Black Powder Coated Steel # 21-3555 you can use the Replacement Hardware for Westin Platinum Series 4" Oval Wheel-2-Wheel Nerf Bars # 21-355PK as replacement mounting hardware.

  • Westin Nerf Bars That Fit 2020 Ram 1500 Classic Warlock Quad Cab
    While we have the exact nerf bars you need, that mounting hardware will not fit the nerf bars you mentioned, as both the mounting hardware and bars need to be compatible. Since those don't fit you should be able to return them to the place you purchased them and get the right nerf bars that I confirmed with Westin are a fit for your 2020 Ram 1500 Classic Warlock with a Quad Cab: - Westin Platinum Series Oval Nerf Bars - 4" - Black Powder Coated Steel # 21-3555 - Westin Platinum Series...

  • What Is the Difference Between Westin PRO Traxx and Westin Platinum Series Nerf Bars
    The main difference between the Westin PRO Traxx # 21-53555 and the Westin Platinum Series # 21-3555 is that the PRO Traxx bars are straighter and will sit closer to the cab of the truck, where the Platinum Series bars extend out a little bit further from the cab. Other than that, they're both made from steel and are covered with a glossy black powder coat so their construction and color will be the same. It's really just a slight difference in style, but both of these bars are a confirmed...

  • Nerf Bars for a 2015 Ram 1500 Quad Cab
    You are correct that the DeeZee Nerf Bars # DZ372251 are fits for the 2015 Ram 1500 crew cab. While there is no exact equivalent from DeeZee, a similar part would be the DeeZee Nerf Bars # DZ372231. If you are seeking bars that ran the length of the cab, I recommend checking out the Westin Platinum Series # 21-3555, which, like the DeeZee, are black rounded bars with non-slip pads. Another option to consider would be the Bully Round Nerf Bars # NB-1215BX; I've added a link showing an...

  • Can Westin Platinum Series Nerf Bars From a 2017 Toyota Tundra Be Used on a 2019 Ram 1500 Classic
    I am sorry to hear about your Tundra getting totaled. Unfortunately, there is not going to be any mounting hardware that will work for the nerf bars off your Tundra to mount them on your 2019 Ram 1500 Classic w/ quad cab. The reason that is the case, is because the mounting hardware is specific to both the nerf bars and truck. The nerf bars also come in different lengths/configurations for different trucks and even cab styles. We could get brackets that fit your current nerf bars or the...
