Westin Nerf Bars - Running Boards - 21-3555

  • Fixed Step
  • 4 Inch Width
  • Cab Length
  • Black
  • Steel
  • Gloss Finish
  • Oval

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!

Review from a similar Platinum Series in Nerf Bars - Running Boards


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.


Comments
Bars are still great. The little ding I simply don’t notice anymore. I’d give it 4 stars, simply because if the ding.

Review from a similar Platinum Series in Nerf Bars - Running Boards


These replaced a set of bars where the pads had deteriorated and cost of replacement was about the cost of new nerf bars. The nerf bars came very very quickly, three days after order. All parts were there, bars looked good, however there was an imperfection in the oval pipe near one of the step pads a small indention. No issues with the box it came in, so my assumption it was during manufacture or warehousing. Not enough of a problem to send back, but it was there non the less. Other than that installed easy, once all tools were gathered, 1st side took 30 minutes 2nd side took less than 15 minutes. My concern is the powder coat may not be durable, and might scratch easy, time will tell. I will probably only have my 2006 Sierra for a couple of more years.


Comments
Thanks for your review. Next time if you only need to replace the step pad, we sell replacement pads. I will attach the link. Just make sure you count how many pegs your pad has so you can determine the right replacement. As for the black powder coat, you can touch up scratches with some outdoor spray paint.

Review from a similar Platinum Series in Nerf Bars - Running Boards


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.!

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. :-)


Comments
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.

Review from a similar Platinum Series in Nerf Bars - Running Boards


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!!

Review from a similar Platinum Series in Nerf Bars - Running Boards


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.

Review from a similar Platinum Series in Nerf Bars - Running Boards


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.


Comments
The steps are great. My wife is 5 foot 2 inches and it makes getting into our 3/4 ton MUCH easier.They seem to be holding up well even though New Hampshire bombs the roads with salt every winter.Other than the minor shipping damage- a great product- very sturdy.

Review from a similar Platinum Series in Nerf Bars - Running Boards


Trailer is one of the best sources for my truck. They are awesome about returns and helped me to pick the right product when I was not sure. The nerf bars worked our great as a replacement to my older ones. They worked out great with the Tundra 2008 and Since I already he'd the brackets from Westin installed long time ago, these fitted just right without much effort.


Comments
Still working great. Thank you for inquiry.

Review from a similar Platinum Series in Nerf Bars - Running Boards


2014 Ram 2500 Crew Cab 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

Wasn't too sure of the integrity of attachment to the rocker panel, but after nearly a year, they seem to be holding up well. Not pleased that the extra 2 or so feet of the wheel-to-wheel version nearly doubles the price, but am pleased.

  • 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...
