2003 GMC Sierra - Westin Platinum Series Oval Nerf Bars - 4" - Black Powder Coated Steel

  • Nerf Bars
  • Steel
  • Fixed Step
  • Westin
  • Black
  • Oval
  • Gloss Finish

The curved ends on these black powder coated step bars give your GMC Sierra 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.

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!

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

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.!



by:

Great steps for a great price!

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!!

Great product and fast delivery.

Very easy to install! They definitely made a difference in getting in and out of the truck. They look good too!

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.

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.

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:

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



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:

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:

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:

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:

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:

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

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.
