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.

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.

I got my Running Boards and they fit my truck prefect they install easily and they look Great Thanks for a Great product and a Great Prices all my friend I have show them and they all say that they made my truck so Thanks again I will be getting other items for my truck



by:

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!

MY SON GOT THIS FOR CHRISTMAS PRESENT



by:

Parts fit and installation was a breeze. The instructions should tell you that brackets have a stamp for location: Driver Side and Passenger Side. Found out via [online] (PF = Passenger Front, DF= Driver Front, PR = Passenger Rear, DR = Driver Rear. Otherwise the running board looks great



by:

Super easy to install, so save yourself a little time and put the little black plastic vanity pieces on before you mount anything to the vehicle..did passenger that way and it was much easier. Even with doing the drivers side the order of instructions it still only took 45 minutes start to finish, had I done both sides with the vanity pieces first probably would have been done in 30 minutes.



by:

We were able to mount the running boards in a bout 2 hours total. They are very sturdy, everything lined up exactly, and they look Great! I had to call tech support because the instructions had not been updated to make sure it would fit my 2019 4Runner. They answered the phone quickly and confirmed that they would fit all the way up to a 2023 4Runner and they were easy to mount!



by:

Installed one year ago on my 2015 Jeep Rubicon Wrangler Unlimited. Installation was simple, with the exception of one thing. To install the step you must permanently remove the "rock sliders" with leaves the bottom seam of the body exposed.
The steps still look in newish condition, except for the color (now dark gray) which has caught up with all the black plastic on my Jeep, thanks to the AZ sun. The rubber tread can be slick when wet.



by:

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.



by:

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.



by:

We really like the look and fitment of the nerf bars, however, the steps are a little too slick when it gets wet.

    The Replacement Hardware # 21-240PK will only fit Westin PRO TRAXX Oval Nerf Bars # 21-24015 and # 21-24010.
