When I received the running boards, the box looked like it was attacked by a grizzly. Luckily nothing was damaged inside. The instructions say that you need a 3/8" wrench, but a 3/8" does not fit, the smaller nut/bolt heads are actually 10mm. The polish around the foot pads looks like it was done by Ray Charles. That said, from a distance these running boards look great, especially if you have chrome bumpers and grille. The install was pretty easy. Now short people can get in and out of my truck with no problem.

2016 Dodge Ram Pickup

Approximately one year ago I purchased a pair of polished stainless steel Westin PRO TRAXX 4-inch Oval Nerf Bars to install on my new 2016 Ram 1500 Laramie Quadcab. The product came with mounting instructions which made the installation process very easy. Subsequently, many compliments have been received on these nerf bars as to how the polished stainless steel enhances the appearance of the truck. Accordingly, I am very happy with these nerf bars and would recommend same to anyone.

Still very happy with the product. Get at least one complement a week, Never a problem with this product. Thank you .

2015 Dodge Ram Pickup

I am very happy with the quality of the Westin Nerf Bars for my Ram 1500 crew cab 2015. However, the rear support had to be changed - PR went on drivers side & DR went on passengers side. A needed requirement for easy entrance to the cab. This makes my wife happy and I have a happy life.


Very pleased with the utility, looks and workmanship of this item.

Great. No problems.


Study abs holding up great.


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


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.


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!


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.


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.


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.


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


Very easy to install and tip to clean off vehicle factory installed threaded studs, first, before installing the nerf bar brackets was very helpful. Fit was perfect!


Great product. Only complaint is I own a 2020 Ram 3500 LoneStar. The rear brackets fit perfectly but the trucks mounting location was different from diagram. There is no opening to fish the brackets which came with bed connecting piece. Modification took about 30 minutes but done. The directions could be clearer for sure but as for etrailer and product itself great.


My nerf bars arrived earlier than expected and they were easy to install. They look great on my 4 Runner!


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.


Order arrived a day early and in perfect shape, awesome customer service!! I wanted a bar that didn't stick out to far and this is exactly what I was looking for. The bars have a nice clean look to them, great welds and very sturdy. I especially like the plastic inserts that hide the mounting brackets. It gives it more of an oem finished look. I watched the install video a few times on etrailer and it made the install very easy. I have to say, if you had to go by the instructions included, it would be a little confusing. With the video, it was clear and very easy. Couldn't be happier with the product and service.


These fit my truck perfectly . Fairly easy installation. Just put them on today but seem to be of very good quality.


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. 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 and Westin the running boards are top notch.


I installed the bars on my 2022 Tacoma upon receiving them from Approximately nine months later, I removed them to gain additional ground clearance.


I like the product very much. One thing wrong was, I am handi-capped and the package was delivered without even a knock on my door. It is too heavy to move. If I was home, I would have asked for it to be put in the back end of my truck.
Now I need to figure out how to get this thing moved.
Hopping they look good on my truck as advertised.


Better than expected. This is my third Westin running boards. This set was the best quality for the price.


These had great instructions, were super-easy to install and look fantastic!!


Good product, great service.


I have had these nerf bars for about a year, on a 2011 Toyota Tundra, and they fit my truck perfectly. They do exactly what they are supposed to do and look great doing it. I highly recommend these to anyone thinking of purchasing them for their own vehicle.
