Great nerfs! Easy install and they look fine on my 19 Colorado. The price was right and etrailer under-promised and over delivers with fantastic shipping! I am 73 years old and had them install with no hoist in an hour and a half. Simple tools and follow the directions for a great install.


Comments
Great! I love them!

I ordered the bars on Friday and received them at my door on Saturday. Granted etrailer is only about 70 miles from me. The bars were super easy to install thanks to the installation video in the item details on this site. And I think the bars look great and feel very solid. This wasn't my first purchase from etrailer, and definitely won't be my last.

After a year these still look like new and winters are usually harsh on everything with road salt. They installed so easily, directions were good and all the holes are already in most newer vehicles, so if you can tighten a bolt you can install them in minutes!

Review from a similar Westin PRO TRAXX Nerf Bars in Nerf Bars - Running Boards


Good points:
The rails and brackets lined
up pervert with the Dodge provided rod posts.
All in all installation was tight and sturdy.

Not so good points:
The stainless finish lacked a brilliant shine that I expected.
Had some dull spots. Stainless thickness gauge seamed a little light.
Installation instructions we’re not clear.
Brackets instructions should have diagram showing the layout.
Hardware could of been labeled better as well.

Review from a similar Westin PRO TRAXX Nerf Bars in Nerf Bars - Running Boards


These nerf bars are great! They are very well constructed, are easy to install, and look good. The fit my 2020 F-350 perfectly. They also are a great price. I went with the matte black finish and it looks great. I like the fact that the ends of the bars welded shut unlike other bars I have had which typically have had a plastic cap over the end. The plastic cap will eventually leak and the bars rust from the inside out. These bars do ride a bit higher than my old OEM Ford nerf bars did. This gives improves the look but creates a higher step. The one thing I would suggest to the manufacturer is to supply a few extra spacer washer in the kit for the purpose of leveling it out visually.


Comments
I still like them. They are holding up just fine.

Review from a similar Westin PRO TRAXX Nerf Bars in Nerf Bars - Running Boards


I got help from Matthew to make sure I got the right set of nerf bars. Order came within a few days. It was easy peasy putting the nerf bars on. The instructions and videos were right on. I’ve ordered from trailer before and every time is an easy task. Thanks and keep up the good work.

Review from a similar Westin PRO TRAXX Nerf Bars in Nerf Bars - Running Boards


First off, aside from making access and egress from a truck much more graceful, running boards just seem to finish a truck off where the rubber meets the road. etrailer.com provided the boards on time as promised.
Other sites I initial ordered from canceled my orders due to accelerated shipping costs. They hesitated, waffled and dodged before canceling, delaying the whole process. Frustrating the living daylights out of me.
The truck (before and after) looks great and things are so much easier.
Thank you so much Etrailer.com and Westin the running boards are top notch.

Review from a similar Westin PRO TRAXX Nerf Bars in Nerf Bars - Running Boards


These do NOT fit a 2013 Dodge Ram 1500 crew cab. The rear brackets do not align with the bolt holes in the bracket. They are off by around 4 inches. The front two brackets are fine. I installed the product due to the hassle of shipping thd product back. Other than that major issue, they are of high quailty and look great.


Comments
The boards are a fit for 2010 - 2018 Ram 1500 crew cab. I recommend watching the video installation that we have on a 2015 Ram 1500.

Review from a similar Westin PRO TRAXX Nerf Bars in Nerf Bars - Running Boards


Quality product. Easy to install on my 2022 Ram 1500 Quad Cab. Ram thoughtfully installs the mounting studs at the factory. You simply attach the mounting brackets to the existing studs then attach the bars and some protective covers to the brackets. It took me 2 hours from opening the box to tightening the last nuts. That included reading and re-reading the instructions. I did the install in my garage, no lift or special tools. I used a 13mm deep socket, a 10mm socket, a 10mm end wrench, and a 6mm hex socket (I didn't like using the included hex wrench).

It was the product that I ordered but the box arrived smashed up and one end completely open resulting in scratched side steps on one side of. It’s rails.

    There are many different options for running boards or nerf bars for your 2018 Chevy Colorado WT Crew Cab.

For polished stainless, I recommend the # 21-54010 with the thicker step.

  • Will the Replacement Mounting Brackets # 21-240PK Fit My 2018 Chevy Silverado 1500?
    The Replacement Hardware # 21-240PK will only fit Westin PRO TRAXX Oval Nerf Bars # 21-24015 and # 21-24010. Unfortunately, these nerf bars are not designed to fit any 2018 Chevy Silverado 1500 models (including Z71). With that being said, there may be replacement hardware available that are designed to fit with your 2018 Chevrolet Silverado 1500 like the Replacement Mounting Hardware for Aries 4" Wide Oval Nerf Bars # AABRKT-S224046.
