      Merideth: Hey guys, so today we're checking out the Mammoth one and three quarter inch billet wheel spacers in black fitting all 2020 and newer Gladiator JTs. So if you are in search of a wider look for your JT, spacers are a great option, and this kit by Mammoth will be a solid choice to take a look at. This kit will be one of the largest options in the category and come with two spacers in the kit and will push your wheel out from the hub one and three quarter of an inch.Now, this size spacer will be for somebody who's looking to go on the more aggressive side with their stance, however, doesn't want the largest option. This will also be great if you've upgraded to a wider tire and you're having some rubbing issues inside the wheel wells, and you're looking for an affordable fix to help your fitment.I would like to mention that this will come with two spacers in the kit. On the table is one kit. What you see is what you get here. So if you're looking to add these to all four corners, you will need to purchase two sets. Now, these will have a 555 bolt pattern, and we'll work with either your stock wheels or any aftermarket wheels that you're looking to add to your JT, or you've already installed on your Gladiator.Nonetheless, these will be very well built, made of a CNC machine, a billet aluminum construction with a semi-gloss black finish to protect the aluminum underneath from corroding. This will also include 10 lug nuts that are pre-installed on the spacers here and will come with some thread locker in the kit to make sure that they will be tightly secure once they're installed.Now, like I mentioned before, this will be a very affordable solution. And this one here will be one of your most affordable options for wheel spacers coming in at roughly $75. Now, again, if you are looking at a set of two, you'll be looking at roughly $150, but still, when comparing it to others in the category, you still will be saving a couple of bucks, even for a set of two.Now, in taking a look at other options on the page, you'll usually just see some different sizes. So you're gonna see one inch, one and a quarter, one and a half, and you'll even see a larger size like two inches. Now, this is going to be for somebody who wants a wide look but doesn't necessarily want the widest look. Maybe you have a specific measurement as far as your fitment is concerned, and one and three-quarter inches is just the right measurement. So this will definitely be for you.Now, there are other options available in the category that will come in some different colors, but again, if you don't necessarily need all of that, you're looking for a very affordable solution, and one of the most affordable options for a one and three quarter inch spacer, and this is gonna be right up your alley.Now, as far as install is concerned, this will be pretty easy at a one out of three wrenches on the difficulty meter, taking about an hour to get the job done with some pretty basic hand tools. The tools that you'll need for this will include a lug wrench, a breaker bar, and a torque wrench. You'll also need a three-quarter inch or 90-millimeter socket and the provided lock tight. You're also going to need a jack to elevate the truck and get the wheel removed.Now, speaking of the install, one of our customers here has installed this on their JT and is going to walk you through the process step by step. So that's gonna wrap up my review. Let's go ahead and get into the install.Man: Okay. So I just wanna recap the tools I used. Again, it's not too many, not too hard. I used my impact driver here with a half-inch extension. This was just to speed some things up. I used my half-inch breaker bar to loosen the lug nuts before I got the truck off the ground. I used my torque wrench to tighten everything down. I used a 20...this is a 19-millimeter socket. As you saw, I switched over to a thinner wall one just to make sure I could fit within the spacer easier. I used a half-inch extension. I used a 22-millimeter socket for the lug nuts and some lock tight to keep the spacer nuts on there nice and tight.Now, you do not want to use this on the lug nuts when you put the wheels back on, otherwise, it's gonna be a bear to get those suckers off when you need to rotate or fix anything. So very simple tools, easy to go ahead and do in a driveway, in a garage. All in all, it took me about 35, 40 minutes.Hey everyone. So I'm gonna be working on my 2020 Jeep Gladiator and I'll be putting on some wheel spacers. Now, these are hub-centric, aluminum wheel spacers, and they are five by five, and they're an inch and three quarters. This is important. I'll show you why on the Gladiator in a little bit, but the wheel studs on the Gladiator are right about to the end. Anything shorter, and you will have to trim the factory studs.Now, this is not gonna be real hard and it's not gonna take real long, and it won't take many tools. So let me show you what I'm gonna be using. I'm gonna start and loosen up the lug nuts with a half-inch breaker bar and a 22-millimeter socket. And then the lug nuts on the spacers are 19-millimeter. So I'll be using that. I've got an extension to help me get the torque wrench on. And then to tighten everything up, I will be using a half-inch torque wrench.Now to make things go a little bit faster, I'll be using my driver. This is just a quarter-inch driver with a half-inch adapter. This is not to tighten anything up. This is just to get things snug. The torque wrench is what I'll be using to get everything really tight. And I've got some lock tight to make sure that the studs or the lug nuts on the spacers don't go anywhere once I get them tightened up.Now, let me go ahead and show you what I'll be working with. Okay. So this is my 2020 Jeep Gladiator. You can see the wheels and tires are pretty well tucked under the fenders. And that's what I'm trying to fix a little bit, get a little bit more aggressive stance and maybe be a little more stable with the wheel spacers. So I already got my jack stands underneath the front, I've got my Jack ready to lift it up, and of course, I've got my emergency brake set. So we'll get started here in just a second.Okay. So with my Jeep still on the ground, I'm gonna use my breaker bar just to loosen up these lug nuts, not get them all the way loose, just so they're a little bit loose. Doesn't take too much with the breaker bar. That's it. I'll start on the other side and then I'll get this jacked up, and then I'll show you how to get it all apart.Okay. So I've got the car up on the jack stands. You can see these are just off the ground high enough. I have my jack stand set and I still have the jack underneath. Now, let me go ahead and use my impact with the 22-inch socket. So go ahead and take these loosened lug nuts off, and this just makes the job a little bit...just makes it a little bit faster. So, nice and easy. We've got the wheel off. Go ahead and move that out of the way for right now.Now, you wanna make sure that there's nothing blocking or that would cause any problems with the spacer going on your stock hub here. So I'm gonna fit them first to make sure everything looks good. Looks great. You can see here if you get in close, this is just enough room for those studs to be cleared. That's why the inch and three quarters is important. If you had a inch and a half spacers, you would have to trim your factory studs.So I'm gonna take this off. And very important, we wanna put some thread lock on these studs, and this is gonna help the spacers stay nice and tight and not come loose, and not have any problems as you're driving down the road. So now you have that on, put the spacers back on. All right, lug nuts on here. These are the ones that came with the wheel spacers. So that'll just take a few seconds there. And now I'm gonna switch my socket over to the 19-millimeter right here. And again, this is not to tighten, just to snug, and this just saves some time as you're putting it together.Okay. So what I was using is an impact socket. You can see it's a little bit thicker wall, so I'm gonna switch over to a thinner wall 19-millimeter socket, just so it can fit in here a little bit better. That's a lot nicer. Again, nuts torqued, not all the way tight, just snug. Now I'm gonna torque these up, but as you can see, the hub does spin. So I'm gonna go ahead and get someone in the car and push the brake, and then we'll get these torqued up to 130 pounds.Okay. So I've got the Mammoth [SP] in the car. He's holding the brake, so the hub will not spin. I've got my torque wrench set to 130 pounds. I'm gonna go ahead. Tighten these down one at a time in a star pattern. As you can see, they were not tight from the driver. Okay, I'm gonna go one more time through these. Again, 130 pounds and that lock tight will keep them nice and tight.Now, I'm gonna go ahead and put this wheel back on and get the lug nut set. Okay. I've got my wheel and tire back on. I'll put the lug nuts on. You can see that bolt pattern is perfect. My factory lug nuts fit perfect. Get this on here. Now, same thing I did with the spacer. I'm gonna use my driver here with a 22-millimeter socket just to get these snug.Okay. Now, I'm gonna switch over to my torque wrench. Still set to 130 pounds still with a friend holding that brake, so this holding system doesn't spin on me here. And again in a star pattern. Do a second time, and that's all there is to it. I'm gonna go ahead, get the other side done. Get the truck down off the jacks.Merideth: So that's gonna wrap up my review and the install of the Mammoth one and three quarter inch billet wheel spacers in black, fitting all 2020 and newer Gladiator JT's.
