Video Transcript for Westin Grate Step Nerf Bars Review

What is up truck owners Today, we're gonna be taking a look at the Westin Grate Step running boards. So these are gonna provide a very, very large step about six and a quarter of an inch to be able to get your feet up on there. Big, heavy construction boots or whatever, to just help you get up into your truck. Whether it's lifted or whatever, we're gonna have a great step to be able to get up and into our truck. This is gonna give us maximal traction. So, when it comes to these, we're gonna have a couple of different options when it comes to length.

And then what we want you to do is use our fit guide to get paired up with the right bracketry for your specific truck. But these, in my opinion are probably the most traction you'll ever get with a running board. So, if that's something you're looking for, this is gonna be the one for you. Basically, it's like a cheese grater. These little, tiny little extrusions in the top, there's a lot of them and they stick up about a quarter of an inch.

If I we're to compare these to any of the other ones that we have on our website, there's two of them that are kind of in the same ballpark. One's gonna be the Aries Ridgestep. That one's gonna be a little bit less aggressive when it comes to the traction. The style is kind of similar to this one, but I do fancy the Westin Grate Step a little bit more. But then the other one that I'm gonna compare it to is the Dee Zee Rough Step.

The Dee Zee Rough Step is gonna be a little bit wider than the other two options. And it's gonna give you a little bit more traction than the Westin and a lot more than the Aries. It's kind of the same deal, but between all of them, I really do like the Westin Grate Step look a little bit better, and there's plenty of traction. I don't really think I need more. But all three of those options are gonna be really great for just getting a lot of that mud and stuff off of your feet.

Whether it's mud or snow, depending on who you are. If you're a construction guy, you know, those construction sites get really nasty and clay, and that stuff just sticks. So this is gonna do a really good job of that, but so are all the other options. And if I we're to compare that to just your basic running board step, the more traction you have, the better you're gonna get all that stuff off of your shoes. At the end of the day, I just kinda found myself just looking at this. Like this is my dad's truck, and I really do like the look. And I think that's the main thing. This is why that's, this one's my favorite of the other three that I would compare 'em to. I just really liked the look of it. It looks super aggressive, looks super good and it's definitely an upgrade. So now, I think the only other thing I kind of wanna show you guys is just a couple of different angles of me driving around so you can see exactly what your truck's gonna look like with these running boards on. So you can see what other people see. So I love the way it looks, especially when it's driving by, you guys can see what everybody else is seeing, and it's definitely turning some heads. So this is my dad's new truck and I was like, "Dad, these don't look that nice. Let's get you some new ones." He agreed. So take a look at this side. It's just, you know, a basic truck and people kinda look at the components on the truck. They're like, "Oh, this guy doesn't take care of his stuff." Or, "It's not an off-road rugged rig, like a truck should be." But then look at this side, this side looks awesome. I don't know if it's just because of the white and black combo, but this looks amazing compared to the other side. And this is definitely a much more rugged look. And this is gonna just be so much cooler to look at and give you a lot more traction as well. So I can, look at this. This is so much grip and you're not gonna slide on these. This is basically the most heavy duty when it comes to grips on your running boards. It's gonna be made of steel and it has an e-coat so you don't really have to worry about this starting to peel or fade or anything like that. These are gonna be rugged to the very, very end. Honestly, they're probably going to outlast your truck. So, let's just say you're getting in your truck. I'm wearing a size 11 shoe with steel toes. So it is a pretty tall boot and I still can get all the way through and utilize the whole entire six and a quarter inches of width to be able to get into the truck. And again, I can't really show you how much traction I'm getting, but I'm really trying to move my foot. I mean, you can just see these different extrusions and just notice that it's just gonna have a ridiculous amount of traction. So, if you have some snow and stuff, you don't have to worry about it, getting all clumped up, like it'll eventually just fall through. So I definitely like this for getting in and out of your truck. And as you can see, I'm literally jumping on this. I'm about 165 wet and there's no give. So a lot of these running boards, especially the ones that we took off had a decent amount of give but these are completely solid. I like that just because I just rather than not have give whenever I get in and out of the truck. But also if you put stuff on your camper shell, or you put it up on your roof, you're still going to be able to grab as much of the step as if we we're to have the door open, to be able to get up and grab whatever we need up here. Maybe if you're not one that has like a roof rack for recreational stuff, maybe you're just a ladder rack person. You have a cantilever over top, this is gonna help you load up your ladders and stuff like that. And we are gonna have different lengths too. So if you really wanted to kind of utilize the back little section so we can get a wheel to wheel with the longer section, so we can load everything up over here. So, whether you're just getting in your truck or putting stuff up on your roof, these are gonna be very, very helpful. One thing to note when I was kind of shimmying across, not getting in the truck, but just getting stuff on top of my roof, I did have, kinda had to hold onto something because they're not out far enough for me to keep my balance on it. But I don't think that's a big deal because I like the fact that they don't go outside of my mudflaps. And I also have a very aggressive tire and some wheels with an inch offset. So it does sit out a little bit. So, they're gonna be protected. Yes, I can't completely balance on there without holding onto something, but that's basically with any running board. But just the fact that they're still going to be protected from, with my mud flap from like rock chips and stuff like that, I really, really like that. It's a perfect look. And as you can see, it's almost completely straight with the outside of my wheel just a little bit in, but it is perfectly straight with my mud flap. As you can see, I am definitely upgrading. I don't necessarily love these types of bars because it's not a one-piece system, right. You have one bar and then you're gonna have the extra little pieces here. You're not gonna see this with the Great Steps just because it's all steel and all that traction that you get isn't just a little plastic insert. It literally is just the metal. A truck in my opinion should be rugged and all the components should be that as well. So these right here, they're just not cutting it. So you're not gonna have to worry about getting replacement parts for the Great Steps like you see with these Nerf bars. And that'll do it for our look at the Westin Great Step running boards..

Fits great! Used an impact gun to install the bolts because the holes in the truck frame were a tight fit but everything lined up well. Lots of adjustment on these but very solid! Very happy with how they turned out!
