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.

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


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


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).

These bars are definitely functional, but they also look great! Installed on a 2019 Ford F150 XL/STX SuperCrew Cab. Instructions were fairly easy to follow.

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


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.

Ordered the nerf bars for my ram truck and received it when promised. Instruction is easy to follow and installation had no issues or problem. I really like the look of these nerf bars on my truck. Easy to order, timely delivery, great product with very good instructions and easy installation. Will order more accessories from this vendor.

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


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.

Still good, no change, no problems! Now in S Florida.

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


I am very happy with the nerf bars. The package was missing 2 lock washers but I had some that fit so it was not a huge issue. Installation was easy. I installed them in a couple of hours. They look great on my truck and make it much easier for my family to climb in and out. I have purchased other products from etrailer (a bike rack and a hitch basket) and they were fantastic also. In my opinion this is a good company with good products and service.

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


These nerf bars are just what I was looking for. Made getting into my truck easier for the shorter members of my family. Installation took a bit of time simply because there are so many screws, but overall installation was very simple. Instructions were straight forward, and no drilling or modifications to the truck. They feel very sturdy once on the truck and offer good footing for getting in or getting to the roof of the truck.

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


The nerf bars I purchased a year ago have held up wonderfully. They have no rust and the color is still fantastic. They were a great addition to my truck. They changed the look of my stock 2019 Ram 1500 completely.

great product, easy installation. looks great on wifes truck. being short , she needed a step to get in . flows nice with the truck body lines. I think the 3;; would have been too narrow . so glad I chose this one.

Excellent product. Installation was easy as long as you're comfortable working on your back. It is very important to keep all bolts loose until you mount the running boards, then go back and torque everything.

These running boards are still solid even with the snow in upstate NY

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


These have been Great. I got these over some others because they have 3 mounting brackets per side for the extra strength & support. My wife & I love them because we no longer have to climb into our RAM 1500 we just step right in. There was nothing unexpected about installation.

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


These are a very sturdy, good quality product! I would like to see the placement of the black step portion changed. It needs to be moved back a little for the driver and front passenger. The black portion is too far forward, so when swinging out of the cab to step down, the left foot for the driver, and right foot for the passenger, hits at the back edge of the step. My husband actually hits behind the black step portion when getting out of my truck, scratching the stainless steel bars with his shoes or boots. I can't comment on the placement of the black portion for the back seat passengers, as I have not sat back there since putting the bars on.


Comments
As I stated in my original review, the rubber steps are too far forward on the bars. When swinging your feet out of the truck to step down, they hit just behind, or at the back edge of the rubber, causing the bars to get scratched up. I can’t say for the back door steps, but the front door steps need to be back at least 6” to put them in just the right place.
