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.


  • 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


  • 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.

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. :-)



Still going strong after a year. A few scratches from rocks but Id rather that than scrape up the truck. Does exactly what I needed them to do.

Oh no! Let me get you over to customer service for them to get this corrected for you.

2014 Dodge Ram Pickup

Shipping box
could have been built stronger, UPS had to add extra tape
Steps mounting nuts are a little to long 1/4" so bolts don't didn't align correctly but once started everything pulls together, can't leave front mount loose to align because you can't get to one bolt to tighten it.
Top of step sits 5" below door
Wife now able to get into truck easily so this was a good purchase.
etrailer kept me updated since this was delayed by the manufacturer which I appreciated

2018 Ram 3500

They look great and the install is pretty straight forward once you figure out what they are talking about. One small dislike is they bow a little when I step up on them (240 lbs) however they bow right back and will hold up it seems. This was only a small issue, negated by the price really. They don’t have a center bracket which may have helped. I’m satisfied though, and would recommend, especially at this price.

2018 Ram 1500

Nice bars for reasonable price. Would have been 5x stars except hardware kit was missing 1x fender washer, a critical part needed to complete the installation. I had to borrow a friends car to run up to hardware store - kind of a pain, but nice bars, nevertheless.

2017 Ram 1500

The bars fit and look great. Easy install with no issues. All hardware was included. Directions were easy to follow. Spent more time looking for my sockets than the installation.

2011 Ram 2500

Excellent quality. Very easy installation. Heavy duty mounts makes this an excellent choice. Very satisfied with product.


Installed easy. Look great.



Great product. They are 2 years old and still look new.


They were pretty easy to install. Look great. Love them.

2015 Ram 1500

I ordered on a Thursday night and received my order on Monday afternoon. Its exactly what was advertised and I'm very pleased with whole experience.


Perfect for short legs



Both items were delivered on time and installed with ease. Love them.





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.


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!!


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


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.


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.


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.


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.


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.


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

  • Will Anything Need to Be Removed from 2019 Ram 1500 Classic to Install Westin 21-3565 Nerf Bars
    You sure won't, except for the tape that covers the mounting holes on the back of the rocker panels. Other than a few pieces of tape, nothing existing will need to be removed. If you use the provided link, you can see a product description video for the Westin Platinum Nerf Bars.

  • 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.

  • Installation Brackets for Westin Nerf Bars on a 2013 Dodge Ram 1500 Crew Cab
    It sounds like you were looking at the Westin Nerf Bars like # 21-3565. The mounting kit for this set of nerf bars will be included in the box with the nerf bars. All of the custom fit Nerf Bars we offer for your 2013 Dodge Ram 1500 Crew Cab will include the mounting hardware, I've linked to this page for you to check out.

  • Recommended Running Boards for 2016 Ram 1500 Crew Cab
    The Bestop PowerBoard NX Motorized Running Boards # B7563815 which fit the 2016 Ram 1500 Crew cab without factory Air Suspension system, do have exposed linkage parts as well as motors and wiring. In a severe Northeast winter these could develop a build up of ice that might potentially interfere with their operation. Since this kit does not fit with the factory air suspension anyway you can instead use a fixed step. My recommendations are the Westin 4-inch black nerf bars # 21-3565 or...

  • Looking For Custom Fit Nerf Bar Brackets For A 2021 Ram 1500 Classic Tradesman
    As install brackets and hardware for nerf bars will all be brand specific, I cannot advise on a replacement without knowing this information, unfortunately. With that said, from looking at the picture you provided, it does look like you have something similar to the Aries Round Nerf Bars # AA205041 or Westin Platinum Series Oval Nerf Bars # 21-3565. Again, this is a guess and both of these are for a crew cab. What you may need to switch to is something like the Aries Oval Tube Steps #...
