How to Install the Demco Classic Base Plate Kit on a 2015 GMC Sierra 2500


Hey everybody, how's it going Today, we're going to be going over and showing you how to install, the Demco classic base plate kit, here on a 2015 GMC Sierra 2,500. So here's what our base plate kit is going to look like when we're driving around town. So something that I really liked the Demco does, is they give you these nice protective covers here. So they do a couple things. They help the base plate blend in with the vehicle more. But they can also easily be removed just by pulling out.

And as you can tell, even with the covers removed, the actual base plate kit blends in with the vehicle well. It installs where our tow hook would be, so it does kind of look similar to a tow hook, I guess you could say. So, without actually looking real hard at the vehicle, you wouldn't actually even be able to tell that you have a base plate kit installed. Which is one of the reasons I really liked this kit. Everything is going to be hidden behind the scenes here.

The only thing we're going to be able to see is just the ends of the tabs for our base plates. So if we take a closer look at the base plate tabs here, you can see everything's made of this nice, thick, heavy-duty steel. And it all has a durable black powder-coated finish. So being as on the underside of the vehicle here, it's definitely going to be subjected to the elements. Therefore, this extra protective coating is going to help things.

Help keep things staying nice and new and clean, with a black finish. So, in regards to tow bar compatibility, the base plate kit here is going to be directly compatible with all Demco tow bars. However, if you have another brand of tow bar, such as the one from Roadmaster or Blue Ox, not to worry. You're still going to be able to use this base plate kit. You will however need a separate adapter.

So now that we've gone over a little bit about the base plate kit here, let's go ahead and show you how easy it is to hook up your tow bar to this. So you're going to make sure that we have both of our covers removed. Those simply just pull out. We'll start on one side here. We'll lift the arms of our tow bar up. So we should have a little slot here, that's going to line up with the two prongs there. And we're basically going to be lining up our holes as well. So once you get everything lined up, we'll take our pin here, and insert that through like so. Then we have our linchpin here on the other side, which we'll insert through the hole on the pin. And we'll close that to lock it in place. And then finally, we have our safety cable here. Simply go ahead and hook that on, to the tab of our base plate, like so. We'll just repeat that same process on the other side. So, in regards to installation, I will say this is definitely one of the easier base plate kits to install. Definitely something you guys can do at home by yourselves. We don't have to make any modifications to the vehicle. Everything is going to simply bolt on using common tools. Let's go ahead and walk you through that install now. To start off out installation today, we're going to be removing the tow hook from either side here. Now in order to remove it, you're going to want to go ahead and get an 18 millimeter socket and an 18 millimeter wrench. So there's two bolts holding the tow hook in place. If we jump on under the vehicle, we can show you those. So if we look at the bottom of the frame, we're going to have one bolt here which goes up, and then we're going to have a cross bolt at the top, that goes through the tow hook. So we're going to go ahead and start by removing this bottom one here with an 18 millimeter socket. Now, if you want to make things a little bit easier on yourself, it would be a good idea to go ahead and spray down both of these bolts here with some sort of penetrating oil. Now that we have that one out, we're going to remove this top one here. So keep in mind, we will be reusing this top bolt and nut here. The bottom one, however, we can discard. We won't be reusing that. But once we get both of the bolts out, we'll just pull our tow hook straight out like this. So the next thing the instructions call out to do, is to place some sort of protective tape here on the inside opening of our tow hook. That way, when we insert the base plate kit, we don't have to worry about any nicks or scratches. So if you have duct tape, that would be probably preferred. But we're just going to go ahead and use some painter's tape here. And it doesn't have to be pretty or precise. We're just going to simply take some take there, and apply it to that opening. To provide some sort of protective barrier between the metal base plate on our plastic fascia. If you're using painters tape, I'd probably actually do a couple layers. So now we're ready to take one of our base plate tabs, and insert it into the tow hook opening on the vehicle. Now, they are labeled. Which side we're working on, the passenger side here. So we're going to grab the one that says passenger. We're going to make sure that we have our cross bolt and nut available for this step as well. But now we'll just simply slide it into the opening. Now, it can be kind of a tight fit. But with a little bit of maneuvering, we should be able to get it into place. So, because it's a pretty tight fit in there, you may want to get a mallet or a dead blow hammer, and just sort of help it maneuver into position. Now we'll show you underneath how far we need to go in, but we're going to be lining up the bolt in the side of the flange for our base plate kit, with the cross bold hole in the frame. So it's going to take a little bit of maneuvering, but essentially here's the hole on the side of our frame. That's going to line up with a hole in our base plate kit here. And once we do get those two aligned, we'll take our factory cross bolt, and on the passenger side, the end of the bolt here, is going to be going inside the frame. So we'll just simply stick in our bolt here. We may actually have to thread it through, depending on how tight of a fit it is. Want to make sure that you don't damage any of the threads. And there we go. Now, before we put the factory nut back on, we're going to go ahead and apply some Loctite here. It's going to come in your kit. Just put a little drop of that on the end of our bolt. So we're not going to tighten this down just yet. We need to make sure our holes underneath are going to line up. So now we're going to be securing the base plate to the underside of the frame. So we're going to need to grab two of our half inch bolts. We're going to place a split lock washer on there, along with a flat washer. And then we're going to need our little plate here. So just to show you ahead of time, the top of this plate here has a welded spacer. That's actually going to line up with the hole in our frame here just like so. But before we do that, we're going to get both of our bolts assembled, and we're again going to place some Loctite on the ends of them. And then we can go ahead and secure them in position. So we'll get one started. We'll come back and insert the other one. So now I'm going to take a 19 millimeter socket, I'm going to snug down these two bolts. You want to make sure that that washer in our plate lines up with the hole in the frame. So you may need to put a little pressure on it, with your hand. So now we'll switch back to our 18 millimeter socket and wrench combo. We'll go ahead and snug up this cross bolt now. So now the final step is to torque down our bolts to the amount specified in our instructions. I'll go ahead and remove that protective tape. And then we'll just simply repeat the same process on the other side. And that's going to do it today, for our look at installation, of the Demco classic base plate kit, here on a 2015 GMC Sierra 2,500..
