Video Transcript for DeeZee Round Nerf Bars Installation - 2014 Ram 1500

Hey everyone. Shane here with Today I have a 2014 Ram 1500. I'm going to walk you through how to install the DZ three inch Nerf bars. Adding Nerf bars or tube steps, as you often hear, to your vehicle is not only gonna add style but it's also gonna give you an easier time getting in and out of your vehicle. Especially, if your vehicle sits a little bit higher.

I'm six foot tall getting in and out of this vehicle with the larger tires on it. I have to kind of jump up into the seat. Adding the Nerf bars again is going to make it much easier when getting in the vehicle the bars are going to be three inches. They're going to be a black powder coat finish. So they're going to look really nice on your vehicle.

Again, add a very nice touch. The steps their selves are gonna be a plastic construction, but they're going to have a they're kind of going to be dimpled, I guess. So it's going to give it a little bit of grip when your feet may be wet. The width of the step is going to be about two and a half inches where you can see the knobs here. They're going to be about 10, 10, and a quarter.

The whole width of the step, you're looking at about 19 and a quarter. Now you're not only going to have one for the front but you're also going to have one for your passengers in the back. The other nice feature I like about these is at the end of our tube, they're gonna have a rubber cap. And what that rubber cap does is it help prevent water from getting inside the tube. It's also going to keep the two metal surfaces from rubbing together.

These steps are also going to be available in Chrome if you prefer Chrome. As far as the installation process, installation process is very simple, straightforward. It's going to come with all the necessary hardware and it's not going to require any drilling or welding. Now we've gone over some of the features let's get in the shop and show you how to put them on. To start your instillation, you can start on either side of the vehicle. They're both going to be exactly the same. You're gonna grab a nut plate like this. It only has the bolt coming out of it. It's just a plate and a plastic retaining a, washer like this. You may or may not have tape on this hole. You do pull it off. In some cases, this hole is going to be small. You're going to take the full wire that comes in your kit the spring end, and you're going to feed it through this hole. And you're going to come out this hole. Then you'd feed your hardware through here and then come out here. In our case, our hole is the correct size. You're going to take your plate. Now they're going to tell you to feed it in there and then put this on. I find that it's easier if you just thread this on partially get it in the hole, and then thread it on the rest of the way it's going to hold your plate in place and keep it from falling into the frame room. On some vehicles, these two holes right here are going to be threaded. You're just going to use the hardware when you get to that point, that fits those holes. In our case, we don't so we're going to have another nut plate. It's going to be a larger bolt. We're going to put another one of our keepers on, we're going to slide it in the hole. We want it to be up towards the front hole here. We'll thread this on. We're going to take our bracket for the front. It's going to be marked. P.F. for passenger front. We're gonna slide it over our bolt. This side is going to get a flat washer lock washer nut. This here, is going to get a bolt with a lock washer, flat washer on it. Doesn't matter what you, we're gonna put them both on. I'm just going to put this one on to hold our bracket in place. Now we can come back and put that hardware on. In our case here, this bolt that's sticking out is not going to be used. We're going to make sure these are only hand tight. You don't want to tighten them down all the way just yet. Now we're going to come to the very back hole. There's tape again, pulled off the top hole. Another one of our nut plates. Put your isolator tab or your puller tab on there. And when we put our bracket up it'll determine which side we're putting this, this the bottom side on. So we'll leave, let it sit like that for now. Gonna grab our bracket. Again, it's gonna be marked passenger rear. You can see how the holes are. That's going to be turning this way. We're going to slide it over just like that. We're gonna use the bolt correct for the threaded portion of that nut plate black washer, flat washer, put it into place like that. And we can come back and we can finish up with a hardware. Flat washer, black washer, and then of course, again loosely installed. 18 millimeter socket and wrench for front body mount. We're gonna loosen this bolt. And then if you want you can use an impact or a power tool to get it out. One thing I will say is on a vehicle this age there's a rubber isolator up in there. And part of it will start to deteriorate over time. The little particles that have deteriorated, may turn into liquids, or if you're using impact once you get down so far, that stuff is going to spray out of there and it will get all over. So just watch yourself. Loosen it first with the impact. You can see that coming out of there just a lot of water right now. We're gonna go ahead and remove this bolt all the way. Once you remove the bolt you're gonna find the bracket that says passenger. You're going to fit it where it's going to fit to the bracket. We'll thread this bolt back up in there. We're just going to thread it in there enough. So it stays. Then we're going to get our hardware installed here to this bracket. Next we're going to take our tube step and each end, it's threaded. We're going to take the large bolt lock washer, flat washer. We're going to go through this bracket through our other bracket. We're going to thread it right into the end of the tube step We're going to do this at each end. Into each bracket. Once we have all our hardware installed we're going to come back and start tightening everything down. We're going to start with our brackets going into the side of the body or the rocker point. 19 millimeter socket for our top bolt here, we can use the five eight socket for the floor one here and then we'll move to our front bracket. Five-eighths here for our front and top over here we obviously can't use our powered wrench. We're going to take a socket wrench with the five eight socket. We're gonna tighten it. Come back with your 18 millimeter socket. We're gonna tighten our body mount bolt now. Next we're gonna come back. We're going to straighten our steps out and get them aligned either high or low, however we want to set them. Come back with a 19 millimeter socket. Tighten these bolts down. I'm going to start with a back one, we can really can't go up any higher with the front here. So I'm going to align the back as high as the front end. Once you get one side done you're gonna repeat the process on the other. That's gonna do it for look at installation on the DZ Nerf bars on a 2014 Ram 1500..

  • Black DeeZee Tube Steps Recommendation for 2016 Ram 1500 Quad Cab
    Since your second set of doors on your 2015 Ram 1500 are not full sized that means that your truck is a quad cab. If the doors were all the same size you would have a crew cab. That means that the DeeZee steps part # DZ372231 that you referenced is a confirmed fit for your truck and would work well.

  • Nerf Bars for a 2015 Ram 1500 Quad Cab
    You are correct that the DeeZee Nerf Bars # DZ372251 are fits for the 2015 Ram 1500 crew cab. While there is no exact equivalent from DeeZee, a similar part would be the DeeZee Nerf Bars # DZ372231. If you are seeking bars that ran the length of the cab, I recommend checking out the Westin Platinum Series # 21-3555, which, like the DeeZee, are black rounded bars with non-slip pads. Another option to consider would be the Bully Round Nerf Bars # NB-1215BX; I've added a link showing an...
