Westin Nerf Bars - Running Boards - 21-3540

  • Nerf Bars
  • Silver
  • Cab Length
  • 4 Inch Wide
  • Fixed Step
  • Stainless Steel
  • Westin
  • Oval
  • Polished Finish

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.


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
  • 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


Specs:

  • 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.

Arrived undamaged. Great fit and finish. Easy install.

Good product



by:

Great product easy install



by:

Sturdy, well made. I'm very satisfied with this product.



by:

They fit great! look good and really help shorter people get into the truck.



by:

They sure looks good. Just got them this afternoon and it started raining about 15 minutes after I started the installation. After reading the installation instructions, I do believe an hour or two and they should be on the truck.



by:

Bolted on quickly and looks good



by:

Shipping & communication were fast & great! However, the product did not fit on my 2011 Toyota Tundra 4 dr as stated. We are having to pay a mechanic to install them - or will have to send back. :-(



by:

I liked how quick the nerf bars mounted on the truck



by:

Solid when stepping on it and finished chrome looks as new



by:

The videos were very helpful. The instructions were easy to understand, and it took about an hour for both to be installed.
The only concern was as I reached the specified torque value on the bar 55 ft. lbs there was some popping and cracking. I believe this was due to the settling of the bar to bracket and bolt to body re-alignment. Overall pretty good



by:

Finally got the running boards installed. My wife loves them. They look good and are very functional. Great service from etrailer, couldn't be more pleased. Thanks for the great service.



by:

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.



by:

Great product - just what I was looking for. Not many wheel to wheel offerings out there. etrailer did not offer this product, but since I like dealing with etrailer, I asked them to put this item in the order system.



by:

Went on easily. Well designed product. Fast shipping! Thank you eTrailer!



by:

Everything was as expected. The installation was a little lengthy but it's a good product and this company does a great job. I would highly recommend them and the products they sell.



by:

High quality, easy installation and good fit.



by:

Very easy to put on and look great!



by:

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.



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:

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:

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



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.

See what our Experts say about this Westin Nerf Bars - Running Boards

  • Will Running Boards from RAM 1500 Crew Cab fit 2500 Crew Cab
    You didn't mention years of the trucks so it's hard to say, but for example the Westin running boards part # 28-51050 fit 2010-2018 Ram 1500 Crew Cabs and 2500 Crew Cabs.

  • Westin 4 inch Chrome Nerf Bars that Fit 2017 Ram 2500 Crew Cab and Regular Cab
    You mentioned two trucks, one is a 2017 Ram 4 door and a 2017 2500 Ram with an unknown cab style so it's harder for me to maybe get you the exact info you need but I will try my best. So cab style is really important for picking out running boards. For example the part # 21-3540 that you referenced would fit your 2017 Ram 2500 if the truck had a regular cab. If instead you had a Crew Cab you'd instead need the part # 21-3560 since the cab is longer and the steps would need to compensate...

  • Will Westin Platinum Series Nerf Bars 21-3540 Fit 2021 Ram 1500 New Body?
    It looks like you are referring to the Westin Platinum Series Oval Nerf Bars - 4" - Polished Stainless Steel # 21-3540 which are confirmed to fit the 2018 Ram 2500 regular cab. This set is not a fit for the 2021 Ram 1500 New Body so you will want to go with a different setup. For crew cab you could look into Westin Platinum Series Oval Nerf Bars - 4" - Polished Stainless Steel # 21-4080 and for quad cab you could look at the Westin PRO TRAXX Oval Nerf Bars - 4" - Black Powder Coated Steel...

  • Would Running Boards from 2018 Ram 1500 Fit 2020 Ram 2500
    There's a large enough difference between the two trucks you mentioned that the nerf bar fits would not interchange so you'd need a new set for your 2020 Ram 2500 like with the Westin part # W57HR.

  • Do Westin Platinum Series Oval Nerf Bars, Part # 21-3545, Fit a 2012 Dodge Ram ST Single Cab Pickup
    Yes, the Westin Platinum Series Oval Nerf Bars, part # 21-3545, will fit all regular (single) cab models in the 1500, 2500 and 3500 series. These custom-fit nerf bars bolt on with the included hardware (no drilling required) and carry a 3-year warranty from Westin. Westin also offers a polished stainless steel version that carries a Lifetime Warranty, part # 21-3540.

  • Westin Platinum Series Over Nerf Bars for 2015 Ram 2500 Mega Cab
    There are 4 inch oval nerf bars that fit a 2015 Ram 2500 Mega Cab, but the Westin Platinum Series Oval Nerf Bars - 4" - Polished Stainless Steel # 21-3540 do not; they fit a 2015 Ram 2500 Regular Cab as well as a 2014 Ram 1500 Regular Cab. Instead, for your 2015 Ram 2500 Mega Cab the correct 4" nerf bars are the Westin Platinum Series Oval Nerf Bars # 21-3575. These nerf bars install by bolting onto your truck so no drilling is needed and are corrosion-resistant. I have added a link to...

  • Will Westin Platinum Series Oval Nerf Bars Fit Both a Ram 1500 and 2500
    The Westin Platinum Series Oval Nerf Bars # 21-3540 that you referenced are compatible with both the Ram 1500 and 2500 with a regular cab for model years 2009 to 2017. If your trucks don't have the regular cab or are not within those years let me know which you have and I'll recommend a specific set of nerf bars that might work for both.

  • How Is a Fish Wire Used to Install Hardware for Nerf Bars on a 2016 Ram
    Fish wiring is a pretty cool way to get bolts up into places that are too tight to fit your hands into. It basically involves threading the wire through the hole where the bolt needs to go with the coiled end going in first, attaching the bolt and block where the wire comes out of an open frame channel and then pulling it back through. There are a couple other variations as well. If you check out the video I attached you will see the process described and shown.

  • Polished Stainless Steel Step Bars for a 2012 Dodge Ram 1500 ST Regular Cab
    The step bars that are the closest match to what you describe and that fit a 2012 Dodge Ram 1500 regular cab are the Westin Platinum series bars that you referenced, # 21-3540. The only difference is that they have a 4-1/2 inch diameter. They are oval, they do have a lifetime warranty, they have curved ends (90 degree), and they are polished stainless steel. I have included a link to all of the step options for a 1500 regular cab for you to view.

  • Nerf Bar/Step Bar Recommendations for 2016 Ram 2500 Crew Cab
    We have a huge selection of Nerf Bars that would be a fit for your 2016 Ram, you can see them by clicking the provided link. I don't blame you for not wanting to go through the dealer! Big Bucks! I'd recommend going with a step bar that's constructed of stainless steel for the best corrosion resistance. DeeZee offers the # DZ372253 step that offers a limited lifetime warranty, but is reasonably priced. I've linked you to an install video showing the step bars I recommended being installed...
