The curved ends on these polished stainless steel 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
  • Polished stainless steel is long-lasting and rustproof
  • 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
  • Lifetime 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 stainless 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.

Satisfied purchaserI had to return a product because my son sold his truck before the steps arrrived. I made arrangements with Cortney, who was extremely pleasant to deal with, to return the steps (running board) first ordered to exchange for ones that would fit the new truck my son purchased. Thanks etrailer and Cortney for you assistance and standing behind the product purchase procedures. I'll let you know what we think of the new steps after they are installed.

2003 Dodge Ram Pickup

Great product easy install


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


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.


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.


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!!


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!


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.


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


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.


High quality, easy installation and good fit.


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


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. :-)


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.


Packaged very well! Easy install! Looks great on customer vehicle! The hardest part was getting the factory bolts out!! Install was done in about 20 minutes! Thanks for a great product, would recommend to anyone!!


This is my third purchase of this type of nerf bar step system and they have proven to be rugged and very functional in Wyoming’s back country and temperature extremes. I ran into a bit of difficulty with this set as one of the nerf bar center supports was incorrectly located. etrailer’s Ashley helped resolve and shipped a replacements. Fantastic customer service as always.!


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!


Good product but did not fit my 2019 F150 with 6'7" bed as claimed by Westin. I was able to get them on, but, they did not go over the stake pockets as they are supposed to. I notified etrailer of the issue and they quickly accepted a fully refunded return … even though I had installed them. Hopefully the product listing on the website was corrected so that no one else will get them in error. KUDOs to the etrailer folks for working with me on this!!


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


Both nerf bars arrived with dents in th em


Product looks nice and installs well but came w a chip in rear of tube. Not a very durable product.

Instructions, luckily very simple, we’re laid out terribly w poor illegible graphics.


The product was flawless: E.Trailer is great when it comes to taking your order and processing it whether it's in stock or "drop shipped" from the manufacturer.

  • Westin Tube Step Recommendations for a 2004 Dodge Ram 3500
    For a set of Westin tube steps confirmed to fit your husbands 2004 Dodge Ram that have a lifetime warranty and attach to the frame of the truck I would recommend the # 21-2310. For a black set I would recommend the # 21-2315. These only have a 3 year warranty though. These options are for the quad cab trucks that have 4 doors. We only have fits for the regular cab trucks and the quad cab trucks. Since you said it is an extended cab truck I assumed you meant a quad cab since regular cab...

  • Replacement Mounting Brackets for Westin Nerf Bars on 2006 Dodge Quad Cab Truck
    Since the nerf bars are designed to fit specific vehicles, you'll need a specific mounting kit for the bars more than one for the vehicle. The good news is that the 2004 and 2006 Dodge Ram Quad Cab both used the same bars. If you have the Westin Nerf Bars # 23-0500 or # 23-0505 you can use the Replacement Mounting Brackets # 23-050PK , but it doesn't appear that those are the correct bars to fit either of those trucks. Instead, the correct Westin nerf bars that are designed to fit the...
