      Merideth: Hey guys, so today we're checking out the Mammoth two-inch billet wheel spacers in black fitting, all 2020 and newer Gladiator JTs. Now, if you are in search of a wider look for your Gladiator, spacers are gonna be a great option. And this option by mammoth will be a good choice to take a look into. Now, this kit will be one of the largest in the category and is going to come with two spacers in the kit, which will push out your wheels from the hub two inches.Now, this size spacer will be for somebody who's looking for a more aggressive look or is looking to go on the side of a more aggressive stance in comparison to any of these smaller options. Now, this will also be great if you've upgraded to a wider tire and you're having some rubbing on the inside of your wheel wells, and you're looking for an affordable fix to help with your fitment.Now, I would like to mention that this will come with a set of two spacers in the kit, so you will need to purchase two sets if you're looking to add these to all four corners. Now, this spacer will have a five-by-five ball pattern and will work with either your stock wheels or any aftermarket wheels that you're looking to add or have installed on your JT already. Nonetheless, these will be very well built, made of a CNC machine billet, aluminum construction, and they're gonna have a nice semigloss black finish on the top to protect the aluminum underneath from any corrosion.Now, this will also include 10 lug nuts, as you can see here, they're pre-installed right out of the box on the spacer itself. And you're also gonna get some thread locker in the kit to make sure that these will be tightly secured once they're installed. Now, again, like I mentioned before, these are going to be an incredibly affordable solution and one of your most affordable options on the page four-wheel spacers at roughly $95 for the kit that you see on the table here.Now, again, if you do need to purchase a set of four of these, you will be looking at roughly double that at $190. However, even when you get a set of four, you will be saving a couple extra bucks in comparison to other choices. Now, when it comes to other options on the page, you'll usually see some different sizing. So there'll be one in a quarter-inch, one and a half, and even one in three-quarter inches making this one of your most aggressive or widest choices in the category. So again, if you're looking for the widest, look for your JT, if you're looking for something, that's going to be a little bit more aggressive than the other options, this is gonna be right up your alley.Not to mention some other choices on the page, you'll see will come in a different color. However, if you're not necessarily concerned about the color, you're just looking for something that's gonna save you a couple bucks while still getting a wide look for your JT, then this is going to be the kit to look at.Now, when it comes to install, it is going to be pretty straightforward. I'm gonna give it a one out of three wrenches on the difficulty meter, taking you about an hour to get the job done. You're gonna need some basic hand tools for the job, including a lug wrench, a breaker bar, a torque wrench. You're also gonna need a 19-millimeter socket or a three quarter inch socket, and you will need the included thread locker in the kit. You're also going to need a jack to make sure that the Jeep is elevated enough to get off the wheel entire and reinstall it after you've installed your wheel spacers.Now, one of our customers here has installed this on his JT and is gonna walk you through that process step by step. Let's go ahead and get into the install.Man: All right, we're gonna start the insulation of the J137102 Mammoth two-inch billet wheel spacer. So got your two-inch, of course, it'd be the same procedure for whatever size it is. First thing you wanna do is get your jack set in place, which I have underneath, and now you wanna free up your lungs.All right. Now, that I've got them broke free we're to go ahead and get the weight off wheel. And I do have my emergency break on, and I do have the tires chopped in the front. All right. Now, that I've got the light underneath the tire, go ahead and come back here. All right. Now, you've got the lugs removed, pull off, try to keep it weight off your threads or your post there.First thing you're gonna wanna do is you're gonna want to put some of your thread lock and the thread lock actually comes in the packaging with each pair. So cut the tip off the end of that, and you're gonna put a little bit of this down the threads. Okay. So now that we got the thread lock on there, we want to go ahead and put our spacer over the post that were already on your vehicle and use their lug nuts.All right. Now, just like a tire, you want to skip around. You don't wanna tighten one side or one bolt too much. Okay. Just snug that one up, skip. That ensures that you are not getting any kind of a bind and skip and okay. Once you get to the last one, now you wanna snug them down so you can stick with that first one and check all of them just to make sure.All right, now, all we have to do is put the tire back on, put the lug nuts back in place, and we are done. Go ahead and get another one there, just a few threads so it doesn't fall off. All right. Once you got them snugged, same thing, skip around. Just give them snug. All right. This should be my last ones, knock them down. So now I can check them all one more time. And that is it. Let jack down and repeat that got three more to do exact same scenario and all of them. And I'll be sharing some before and afters so you can see the difference. So that's it. Thank you very much.Merideth: So that's gonna wrap it up from my review and the install of the Mammoth two-inch billet wheel spacers in black fitting, all 2020 and newer Gladiator JTs.
