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.

Installation of Nerf Bars was a breeze. So easy using the factory mounting holes. Perfect size for the regular cab truck.
Thule rack also straight forward install. We plan to load it up this week and really test it out. Looking forward to putting all of this equipment to work.



by:

These rails look amazing on my truck!! Only reason for 4 stars instead of 5 is the drivers side and passenger side are different and instructions only displays drivers side. 1.5 hour installation still not bad!



by:

These arrived a day earlier than was told. The box was in good condition and all of the parts were included. The installation instructions were good and the online videos helped. I installed them right after they were delivered. The bars look really good, I'm surprised at only 3 mounts per side though. Kinda looks like it should have 4. They are solid and I'm expecting many years of use.



by:

I haven't had any reason to dislike the nerf bars I purchased a year ago . They look good on my truck and the way they were installed in exactly right place . At times I wish I had got stainless but other than that , they are perfect .



by:

I like that feel very solid no flexing when anyone stands on them. I have had a couple of friends who really like the look of them on the truck and ask where I got them. After one year of them on my 2022 Colorado I have had no problems at all.



by:

Made it easier to enter the truck. Not to hard for one person to install by themselves. I love the way they look.



by:

Look great! Easy to install! Glad we purchased them.



by:

Quality of the product is great, however the instructions weren't very clear. Now that they are installed I am very happy.



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:

Perfect fit easy to install

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.

Ordered Westin 4" running boards cab length for 2024 Chevy 2500. Product arrived quickly and matched exactly as ordered. Perfect fit and easy to install. Would highly recommend.



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:

Extreme helpful determining the right product and getting it to me quickly. It was exactly as advertised and installed easily. Continues to work even better than expected. Thank you.



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:

Easy installation and a nice upgrade for my truck.
