The Westin Protraxx 4 nerf bars are a nicely made kit. The bars and brackets fit together very well in the factory rocker panel/sill location. All told when fully assembled, the kit looks nice and is very sturdy. It's a nice nerf bar kit. Just could use a few minor details corrected to make it a solid long term no-hassle installation.

The only functionality issue I found with the bar kit is that it seems the placement of the front door tread plates seems a bit too far forward. When you put your feet down to get out of the truck, it feels like the tread should be about 6 inches further rearward for your foot to land on. Placing your foot on the smooth bar is dicey, especially if wet, so you definitely want to step on the tread plates. Getting into the truck on the driver side, seems like the tread placement works OK since you put your forward foot up to the bar first.

Regarding assembly, it takes a bit of patience to get the brackets fitted into the proper locations and get the bolts started in the clip nuts. The hardware kit is a high quality collection of nuts, bolts and washers. However, I think the choice of button head socket screws for securing the bars to the brackets was for aesthetic purposes. The button heads are black zinc and shallow, smooth heads which limit exposure beneath the bar- a nice visual touch. But unfortunately the button heads are are FAR too easy to strip (the head, not the screw threads) when tightening them to the specified torque. Even with a brand new socket bit it was far too easy to booger the head when tightening them. So I chose to replace the button head screws after initial installation with common socket head screws (gray colored zinc-aluminum coated to help resist corrosion here in the rust belt midwest) and that'll avoid any major swearing should they need to be removed in the future. All the swearing is already taken care of now, after removing the stripped button heads with vise grips or a large extractor bit cut to size.

One fitment issue I had with my kit ('17 Silverado Crew Cab) is that some of the plastic covers for the hanging brackets do not align with the holes in the brackets themselves. I think Westin updated their kit with revised front and rear end brackets but the plastic covers remain universal and properly fit only the middle brackets. I had to trim the plastic covers with a razor knife in order for the mounting holes to work well. Without trimming, the plastic covers would interfere with the bracket and therefore they would not mount evenly on the bracket. Not a big deal to do. Just shouldn't be necessary.

As the instructions clearly state, you definitely need to occasionally treat the polished stainless with some wax or metal polish. Over time the bright finish will dull (and scratch- another reason not to step anywhere except the tread plates) and and show pinpoint rust spots. Yes, stainless actually rusts when it encounters nasty stuff like road deicing salt.

I bought the running boards for my husband for Fathers day and he loves them. It makes it so much easier to get in and out of the truck. We are planning on buying some for my truck next. This team has been great working with, thank you all.

My product arrived 2 days earlier than expected, everything I needed to install my running boards was in the box, I also watched the video on how to install the running boards, it was very easy to follow. I would recommend this product to my friends or anyone, and by the way Shawn was very helpful polite and knowledgeable about the product, Thanks for everything



by:

Installed easy and look good. Have had 1 year vehicle garage kept low miles no signs of deterioration.



by:

Easy and great install. Make a world of difference.



by:



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.



by:

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!



by:

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.



by:

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



by:

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.



by:

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.



by:

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.



by:

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.



by:

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



by:

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.



by:

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