Review & Installation Video

Review & Install Video

So the Pro Traxx from Westin will be one of your most affordable four-inch options on the site, along with the Barricade and Raptor Series stuff, in the low $200 price range with these 30-degree ends. Now, prospective buyers will be saving some money by grabbing them in black, which we have here, but can be had in polished stainless steel as well, also on the site for about $100 more. Installation is going to get one out of three wrenches on the difficulty meter from me, but we will have a little bit more detail on that later on. Now, the land of aftermarket sidesteps and nerf bars is a rather large one. Different sizes, ranging from three to six inches, different lengths, different finishes, different end designs. You get the point, right? The important feature you guys need to keep in mind here with the Westin is that four-inch oval design, which in my opinion is going to be a nice middle ground when shopping for an aftermarket sidestep or nerf bar. It's enough to give you some improved footing over those factory options, in regards to more real estate, making entry and exit a little bit easier. But at the same time, you're not going to have some huge things hanging off the bottom of your cab, like some of those six-inch options. But at the same time, it's a kind of give and take thing here with sidesteps as well. Because, yes, you might not like having a couple of telephone poles hanging underneath the cab with those larger options. But at the same time, you're not going to get the same amount of footing by going with a smaller diameter bar, like a three or four-inch option. So again, it's kind of a give and take. You have to decide what's most important to you and your truck. Now, Westin as a brand is one of those companies that doesn't really need a big introduction, because they're certainly one of the heavy hitters in the industry. In fact, they have over 20 different running board and nerf bar options alone. Now, the Pro Traxx that we have here is one of the company's more entry-level or affordable options, and the low $200 price point will certainly reflect that. Now, with all that said, the construction here for an affordable option is still very solid throughout. Full stainless steel build finished in that black powder coat, which is more of a satin finish here in the shop, all backed by a three-year limited warranty. The traction area is one of my favorites in the category for this price point, and does feature a whole lot of real estate here for both the front and rear passengers, along with a textured ABS plastic finish, which is slip and UV resistant. Now, I know it's a bit tough to see here on the table, but the Westins do feature those 30-degree ends, in addition to the Raptor Series options as well, when shopping for a four-inch bar in this price point. Now, if you wanted to go with a 90-degree end and stick in this price point, the Barricades will be your best bet, as they will be priced in the same ballpark as the Westins here. Some people might even argue that those 90-degree ends make for a more cleaner look as they kind of dead end into the cab. But ultimately, guys, that is your call and we do have a few to choose from here on the site. But aside from the construction and the diameter here with the Westin, some of the other details or benefits to look forward to when installing something like this, obviously, making entry and exit a little bit easier in your F-150. But also, will help protect you from door dings in parking lots, because these guys tend to stick out a little bit further and offer you a nice little defense there. Switching gears, let's briefly graze over some of the big, juicy details of the installation. Honestly, guys, this one is extremely straightforward. So one out of three wrenches on the difficulty meter is what you can expect here, and anywhere from an hour or two from start to finish, depending on how fast you work. Tool-wise, even more basic. Just a socket set is going to be doing most of your heavy lifting for this install. But Westin also includes a six-millimeter hex bit that will be used as well. Getting started, you'll need to remove the factory sidesteps or any other aftermarket sidestep before proceeding. Once everything is removed, go ahead and install the included brackets using the included hardware, making way for the new sidestep bars. With the brackets installed and the hardware tightened up, go ahead and install the sidestep bar from Westin. With the bars adjusted, go ahead and tighten up your hardware and your installation is complete. Wrapping this one up here, gang, if you're looking for a super-affordable four-inch option from one of the most popular names in the category, you'll want to check out the Pro Traxx from Westin, right here at

Improved Style and Access. The factory installed running boards are definitely a nice option to assist you getting in and out of a F-150. However, for the owners that have a truck that wasn't equipped with running boards, you may have a difficult time getting in and out. That is where Westin comes in with their Pro Traxx 4 inch Oval Side Step Bars. These Side Step Bars are designed to mount to the rocker panel and feature a wide and secure non-slip stepping surface that will make it easier for you and your passengers climbing in and out of your Ford. Not only will you get a convenient step but the intimidating black finish will tie in perfectly with the other black trim and accessories installed on your rig.

Quality Construction. Westin manufacturers these Pro Traxx Side Step Bars out of 4 inch mild steel oval tubing for strength. Each Side Step Bar features a 30 degree OE style bend with fully welded domed ends to provide a clean and seamless appearance. It is then completed in a black powdercoat finish to provide superior resistance against corrosion. To ensure reliable footing, the Side Step Bars include heavy-duty non-slip and UV resistance step pads that are designed with grooves to drain moisture off the step and keep it dry.

Bolt-On Installation. Westin engineered these Side Step Bars to be a direct bolt-on upgrade using basic hand tools. There is no drilling or cutting required, which will provide a clean straight forward installation. All of the necessary hardware is included to make this an easy job for anyone to complete.

3 Year Warranty. To maintain their high standards in quality craftsmanship, Westin backs these F-150 Side Step Bars with a 3 Year Warranty. Some exclusions may apply, please see manufacturer's warranty for complete details.

Application. This pair of black Westin Pro Traxx 4 in. Side Step Bars are designed for the 2015 to 2019 SuperCab and SuperCrew F-150s.

    Side step

    Bought 4” Westin side bars. Took about an hour to install. Parts packaged well and throughly labeled. Instructions easy to follow. Fit without problems. Makes easier entry into vehicle. Like the welded ends not cheap plastic ones. Plenty of room for your feet and extend well for second doors on crew cab. Arrived in a timely fashion.

    Great Product

    Kit was complete and installation was straightforward on my 2017 F150 Supercrew. One minor issue: The front bracket on the driver's side interfered with the parking brake cable. I used a hole saw to cut a semi-circle notch 1/2 inch deep in the bracket.

    My WESTIN PRO TRAXX Oval 4" Side Step Bars was exactly what I needed for my new 2018 Ford F150 XLT truck. The 4" bars are not too big nor too small they are just right. And, installation was easy even though there are lots of bolts, nuts and washers. Everything fit just right and installed in about an hour.

    Westin Pro Traxx 4 in. Oval Side Step

    I have truly enjoyed the comfort that these steps allows my wife to easily enter and exit smoothly. This was the biggest complaint from people of shorter stature about my truck. These bars have possibly saved my marriage.

    Great Heavy-Duty step bars

    These are great step bars, heavy duty and well designed. They were easy to bolt on and look great. The step is in a good location and don't stick way out, but are in the perfect position when the doors are opened.
