Video Transcript for Westin PRO TRAXX Oval Nerf Bars Installation - 2015 Ford F-150

Today on our 2015 Ford F-150, we'll be installing the Westin Pro Traxx Oval Nerf Bars. They are part number 21-23935. These cab length oval bars will make it easier to get in and out of your truck while looking factory installed. They offer greater stability than round bars, and have sealed ends to keep out moisture. The sturdy plastic resists UV rays, and fading, and cracking. The bars are made from steel with a black powder coat to resist rust and corrosion.

It's quick and easy to install with no drilling required. Here's what our Nerf bars come with. Obviously, we have the Nerf Bar here. We have our bracket for the driver front, notated by the DF on it. Each one's marked so you don't have to worry about mixing them up.

The right front will be marked PF for passenger front. We have another bracket here that attaches to that. On the back, it's the same thing. Again, driver's rear notated on it, identical bracket there. All four of them are the same. Here's our hardware.

We have our bolts to secure the Nerf Bar to the bracket, lock washers here, the washers for that, and then the washers, lock washers, nuts, and carriage bolts for mounting our brackets to the vehicle itself. Additionally, we have these plastic shims here that are used to prevent the corrosion from forming since we're mounting a steel Nerf Bar to an aluminum body truck. Also, it does come with a 6 millimeter Allen key to install the bolts that hold the Nerf Bars to the bracket. However, what I would like to do will be using a 6 millimeter socket that I had with the Allen key on it just so I can use it on a ratchet to speed up the process a little bit. I need a 6 millimeter, a 13 millimeter socket.

I have an electric cordless ratchet here to help speed up the process a little bit, and finally a torque wrench. Those are the only tools you'll need to install these Nerf Bars. Now on the rear of our vehicle on the Rocker Panel, you'll find 3 of these threaded studs hanging off of it. That's where our rear mount goes. Right now, I'll take one of those clear plastic corrosion inhibitor shims. We'll install them on the studs. Just push it on it and give it a turn like you're threading a nut on while you do it just to run it down. It speeds up the process a little bit. We'll do that on all 3 of the studs on our back bracket. With those on, we'll do the same on the front. Starting off our rear bracket here, have it positioned like this. We'll take this flange here, install this carriage bolt from the backside like so in the middle hole. Stick it on like this. The flat ridge here will face up on all of our brackets. Take our flat washer and our lock washer, and we'll just loosely thread this on for the time being. Now, we can assemble the front bracket about the same way. We'll just slide them over the studs. We'll place a flat washer on, lock washer, and then one of the 8 millimeter nuts, doing the same for all 3 of those studs. We'll do the same on the back one now too. We'll take our rear bracket . Our bracket's loosely installed now. We can set our Nerf Bar on top of them and start the bolts for those. Then, we'll tighten everything up. We'll just raise it up, center the holes over the bracket, and let it rest on there. We'll take one of our Allen bolts here. We'll install a lock washer on it, and then a flat washer. We'll thread it into the hole. There'll be two bolts on each bracket, just loosely for now. Make sure you get them in straight, and they don't cross thread. Move on to the front bracket and we'll do the same. We'll use our 13 millimeter socket on our ratchet, and we'll tighten the 4 bolts on each bracket starting with the one that bolts the 2 brackets together first, and then the 3 to the body. We'll do the same on the front bracket too. Now, we want to try to level the Nerf Bar out, because as you can see you can rotate it a little bit and it will change the level of the foot pad. What I try to do is push it all the way towards the back, that way the foot pad's the most level. Now, we'll take a 6 millimeter socket and we'll snug up those bolts too. Doing the same on the front . With all of our bolts snug down, we can now torque them down with specified amounts found in the instructions. That completes our installation on the driver's side. We'll repeat the exact same process for the passenger side. That completes our installation of the Westin Pro Traxx Oval Nerf Bars that are 4 inches in diameter with a black powder-coated steel finish, part number 21-23935 on our 2015 Ford F-150.

Truck running boards arrived on time just like they said 3 to 5 days. Where easy to install, but one had a dent in it.It was on the bottom so it won't show. I think it was done by rough shipping, the shipping box was kind of tore up. So it was'nt etrailers fault. Overall was pleased with product. 306530

Very well built, easy to assemble, I probably spent more time counting and separating the nuts, bolts and washers than I did in the entire assembly total maybe 1 hour. Very sturdy I felt no flex in the bar at all when I stepped on it, my wife can now get into the truck without my help. Highly recommend. Drops the step height from the truck to the ground about three inches 640292

Review from a similar PRO TRAXX 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. 654706

Very nice and fit great. On my 2017 Ram 1500 SLT crew cab, it was easier to install the Westin black covers on the brackets before installing them on the rocker panels. I suggest going over the install booklet and organize all the bolts, nuts,washers and brackets in the proper order to driver -passenger side. Thanks! 515496

After a year and a little bit of abuse the product still looks like new, I really didnt think that would be so durable, its amazing. I have an F 350 7.3 Diesel and I really use it, Im a sportsman so get a lot off the beaten path, Mud, Snow,ice and other stuff are common beneath the truck, but just some water with the hose and its new again, best purchase ever. Thanks etrailer for the good parts....

I love the super fast and free shipping from etrailer. Already referred them to a couple of work friends that are looking for accessories. As for the nerf bars, not exactly the quality that I would have hoped for but, comparing price/quality, I have to go with 5 stars. I could have spent a lot more. They look great on the truck and only time will tell how they hold up. Westin has never failed me and neither has etrailer. 727337

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


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. 399666

One year after installation and these step bars still look good. No visible rust on the steps, brackets or hardware. I frequently drive down a long dirt road to a relatives house and the paint is holding up great. These steps help the wife get in while not being too low as to affect ground clearance much. Overall a good purchase and transaction with etrailer.com. 256600

These are nice looking, affordable entry steps. Shipping was as expected and had a couple minor blemishes when all was said and done. The directions were less than clear and skipped around a bit for me. They seem solid and hopefully they will last awhile. 592922

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


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. 522206

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. 611352

Received shipment yesterday morning in excellent condition. Installed. The packing cardboard served as a excellent work surface on this rough gravel. All parts were available and went together easily. I found that drilling the recommended 1/2" hole in the frame is unnecessary for me. Looks good, very stable, very happy. Thanks etrailer.com. 636059

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. 585238
