      Justin: If you're looking to discreetly store and secure items in your 2019 and newer Silverado or Sierra, well, then the Tuffy Under Seat Storage Lockbox here would be an excellent choice. Now, the Tuffy will provide durable 16-gauge materials, 3,500 cubic inches of storage space, along with a no-drill install, all for right around that high $400 price point.All right. So if you guys didn't know, Tuffy does specialize in one big thing here, and that is security products for a wide variety of cars and trucks alike. Now the under seat lockbox that we're talking about here today is right in the wheelhouse for what Tuffy does well, bulletproof protection. So what do you say we break this thing down a little bit more? Now on the surface, guys, it's not a terribly complicated product, right? Again, 16-gauge steel lockbox that is going to live underneath the rear seat of your Sierra or Silverado.Now, when the seat is fully folded down, no one really is the wiser and you really can't even tell anything is there, especially if you're looking through that back window. But flip up that backseat and open up the box, and again, you are greeted with 3,500 cubic inches of interior storage space that can be used for whatever it is you had in mind, right? Firearms, tools, cleaning supplies, sporting equipment. The sky is essentially the limit there.Now that 3,500 cubic inches of interior storage space does come thanks to the larger dimensions here. In fact, we got about 55 inches in length, 10 inches wide, and about 8.5 inches tall. Now that 16-gauge material is incredibly burly and does keep things nice and secure, thanks to additions like the pry-guard locking system with 10 tumbler double-bitted security locks, and there are some built-in weather seals here to keep everything nice and dry.Now the thick steel is then fully welded before being finished off in a very light textured black powder coat that does help keep things nice and stealthy once installed. Now the box itself does feature kind of this 80/20, 70/30 style split here, which some people enjoy, others, maybe not so much because they like to store the rifles, whatever. I do wanna mention, guys, that the box itself is not divided. The lids are, but the box itself is all one piece here. So you can still fit longer rifles in the box. You just have to contend with the two different lids.Now on the topic of the lids, some owners don't necessarily enjoy the fact that Tuffy does utilize different keys for each lock here. It can be a bit cumbersome, maybe a little frustrating, especially if you lose a key. But regardless, the box does have a bunch of four and five-star reviews back on the site. Lot of solid feedback. So, as always, guys, feel free to check those out before pulling the trigger on the Tuffy. But now what do you say we switch gears and get into the install, guys?And one of the nice things about the Tuffy is that you do get a very secure install but without needing to do any drilling. Big fan of that. Certainly, don't like drilling into my brand new truck, and that isn't the case here. Because of that, the site is gonna call this a one out of three wrenches on the difficulty meter and 30 minutes or so from start to finish. But to give you a better idea of just how this one will go down at home, here is an AT customer to walk you through the job now.Man: Hi, good afternoon. I'm working with the Tuffy Security Products. It's a 2019 and up Silverado, Sierra under rear seat lockbox number 352. As you can see here, this is the actual lockbox itself. And as you move to the rear of the vehicle on a 2021 Chevy Silverado 1500, it'll be working with the Trail Boss right now. It has a stock storage container underneath the rear seats. Right now, mine already had removed one of the jacks that was here. Currently, the actual jack mount is right here, and you will need a 10-millimeter socket, preferably one that is longer so that you can actually remove this. But until we do that, we are actually just gonna take this out real quick just by loosening the actual jack itself. After that, you're going to remove the bolts that hold down the jack. And that's one, and two. And this guy should come out just like that. Obviously, keep your bolts. You never know if you're gonna need them again once you do the removal. So, all this come out just like that. We got one more down at the other end here. Looks like a plastic 10-millimeter bolt that is holding on the remainder here. All right. And this is what that one looks like right there. And then it should all come out just like so.Going to step three, you're gonna go where the right side and remove the 18-millimeter OEM outer seat mount bolt which is here, as well as down there at the end, which we'll get to both ends. And this will be the process of which you will loosen this up and eventually use this bolt as a means to secure your bracket for your lockbox. Okay. That's one. Moving on to an additional one on the right side or the driver's side. You will do the same thing. This might be a little easier if you use a larger wrench. However, if you have a smaller wrench, just a little more muscle, And again, eventually, this will get finger-tight. And to avoid getting any of the securing stuff from the bolt-on stuff in your car, just put it on your mart. All right. Now we're gonna move on to mounting the actual brackets. Currently, see here, this is your bracket, and you will have one for your mounting bracket for passenger side and one for your driver's side. What you're gonna want is the flat side facing out to the door, as you can see here. So this is gonna end up being your driver's side, and this one being your passenger side. And you want this part that's flat, the L-bracket portion of it to face downward. And this is what you're gonna have right here.And from what I can tell, you're gonna shimmy this underneath your bracket here, the seating mount right there, and then all you're gonna do is replace that bolt. You wanna make sure everything is in line, and that's all you're gonna do. You're gonna make sure it's hand and then start tightening. I would leave it loose before officially tightening it down either, you know, with your hand-tight or utilizing a torque wrench in the event you want to. However, I believe it's slightly loose as you do the install to give you some freeway with the actual lockbox itself. All right. So we got a little bit of movement now. It's almost tight. So we're gonna move on to the next one. I'm just gonna do the same thing. We're gonna shimmy this right underneath the seat itself. You may have to lift it up a little bit. There we go. Just a little like that, just like so, and then kind of shimmy it on over. There we go. And we can start it finger-wise. It gets tight pretty quick, so just go back to the wrench and do the same thing.Once you get it pretty tight, not fully tight yet because you wanna be able to move it in the event it's not lining up properly with the lockbox. We'll leave it slightly loose. And now to put the lockbox up in here. As you can see, this is simply a one-person job. If you have another person, it might make it a little easier on you. However, pretty easy. All you're gonna do, line up the mount and then use the parts kit provided. Multiple sets of keys, which is actually really nice, but they come with multiple, and the other parts kit here, which is gonna have your bolts, some of your wing nut, wing knob nuts, and then some washers, as you can see here. So I'll go ahead and open this guy up.And all you're gonna do is on the second sheet on the backside of the instruction sheet, you're gonna have your silver bolt, which is a 5/16 by 3/4 carriage bolt. You're gonna go from the rear of it where it goes from your bracket located here. And you can grab both if you'd like and hold them both right there. And you can kind of shimmy scoop the actual mount itself right over to the bolts.And then as you see here, I'm gonna go with a washer. You're gonna use your washers and then basically the wing knob nuts right here. Washers first, wing knob nuts, just twist it on there. Get it started so it holds it in place. Same thing with the left. And I imagine this is actually a really nice feature and I'm glad they did is in the event you ever wanna take it out, or maybe make additional storage, or if you wanna do your own jobs, which I've seen for other people who has put in some Felts within this thing, makes it easy to actually take this out and/or re-tighten in the event it gets kind of shake and loose over time. You don't need a tool to do so.All right. Now that we got this side tightened, before we tighten anything else for the actual whole harness to the seat, we are gonna do the same thing we just did there on the other side. Same thing. Silver nuts will go here. And then in the event they doesn't line up all the way, which is what we have going on here, we can shimmy it down, which is why you wanna leave things a little loose. And there we go. Once they're in, do that. Some washers, wing nut knobs again. Once you get them started now, what should you see? What you can see on these is that these bolts have a little square fitting, and that actually does fit all the way through to the other side of the actual lockbox itself. So to have a more flush and secure finish, it is best to ensure that is happening as you tighten this lockbox further. If I can get this one going. Apparently, I'm not a good lefty. All right, there we go.So get it tight, all sides. Hand-tighten everything, nice and secure. And do the same thing to the left side or the passenger side. And then what you can do once that's all said and done, go ahead and shut it up. Grab your 18-millimeter wrench and socket. I apologize I don't have an 18-millimeter socket, and tighten her up. You're gonna want this actually really tight, which is why I think they recommend using a torque wrench because this is how your seats are secured. So make sure you're fully tightened to how it was installed. All right. That should do her, and that's what you got.Justin: All right, guys. So if you are looking to keep your stuff a little bit more safe, a little bit more secure in the interior of your 2019 and newer Silverado or Sierra, well, then be sure to check out a lockbox from Tuffy right here at americantrucks.com.
