      Merideth: If you're in search of an affordable way to get a wider look for your Jeep, these Mammoth 1.75-inch Billet Wheel Spacers in Black will be a good option to take a look into for your 2007 to 2018 JK Wrangler. Now, this will be one of the wider options in the category if you're looking for a decent amount of poke out of a spacer to achieve an aggressive to a very aggressive stance.Now, this will also be a great kit if you've upgraded to a wider tire and you're having some rubbing inside the wheel wells and you're looking for an affordable fix to help your fitment. Now, this kit will, again, be one of the more aggressive options when it comes to sizing. Now, this 1.75 of an inch will offer enough width to create more of an aggressive stance with the factory wheels or any aftermarket wheels depending on the offset.Now, that wider stance won't just help out with the aesthetics but also when it comes to stability when driving on the road because of that wider footprint. I would like to mention though that this will come with two spacers in the kit here. What you see is what you get. So, if you're looking to put these on all four corners of your Jeep, you will need to purchase two sets. These will have a 5 by 5-inch bolt pattern and work with either your stock wheels or any aftermarket wheels that you pair with them or that you've already installed on your Jeep.And these will also be very well-built made of a CNC machined billet aluminum hub-centric construction with a semi-gloss black finish to protect the aluminum underneath from any corrosion. These will also include 10 lug nuts. As you can see, they're pre-threaded on, on the spacers right out of the box. And this is also going to have threadlocker included in the kit to make sure that these are gonna be tightly secure once they're installed.Now, like I mentioned, these are gonna be an incredibly affordable solution in comparison to other solutions and one of your most affordable options for wheel spacers at roughly $100 for the kit. Now, do keep in mind though that if you wanna add these again to all four corners, you will be looking at about double that price. Now, nonetheless, for the wide appearance that you're getting compared to other smaller options and the subtle black look and the quality build, I definitely think that $100 is worth that price for a good set of wheel spacers, and this is going to bring that to the table.As far as install is concerned, this is gonna come in at a pretty easy one-out-of-three wrenches on the difficulty meter, taking you about an hour to get the job done with some pretty basic hand tools. Speaking of the install, one of our customers here has installed this on their JK and is going to walk you through what that process looks like step by step. So that's gonna wrap it up for me. Let's go ahead and get into it.Connor: Hey, guys. So before we get into the installation here, the tools I will be using, I got my impact, a 19-millimeter, and a 22-millimeter. The 19-millimeter will be used to put the wheel spacers on, and then the 22 will be obviously to take your tires off. I got my torque wrench here. And I would recommend getting a pretty decent-sized pry bar. Those rotors will spin on you when you're trying to torque those lug nuts down.Hey, guys. My name is Connor, and I'll be showing you how to install these 1.75 wheel spacers you can get on All right, guys. So, obviously, you wanna put your Jeep on a pair of jacks like I have here. So you wanna take your impact, and you wanna remove the lugs on your tire.All right, put your lug nuts off to the side, and we'll just take the tire off. And then you can wheel this off to the side. And next, I will be showing you how to put on your spacers. All right, so, you got your Loctite that they provide you, so what you're gonna wanna do is put some of this directly on your studs. And be pretty generous because this is what's gonna hold the spacers pretty well to get pretty good on your studs.So, now, you're gonna want to put this on and then put these lug nuts on. We're gonna need an extension to put these in. And the size that I am using is 19-millimeter. So we'll just get these by hand, tighten them with your hand, and then we'll go back over with the impact and tighten from there. All right. So now we're gonna tighten these down with the impact.All right, guys. So, after you have done tightening your lugs, you take a torque wrench and set it to about 120, 125 foot-pounds of torque and then just go around your lugs, tighten them all down to torque spec. Every car is gonna be a little different, so I'd recommend looking up your car's torque specs. You can find those on, or you can just look them up.All right, so now we're just gonna put our lug nuts back on. And if you do have off-factory wheels like I do, there are certain holes that they go in. I would recommend putting the spacer onto your factory rim on the inside part just to see what holes match up so that you're not messing with it trying to put it on. I'm just gonna take our impact and scroll it in.Merideth: So that's gonna wrap it up for my review and the install of the Mammoth 1.75-inch Billet Wheel Spacers in Black, fitting all 2007 to 2018 JK Wranglers. And remember, for all things Jeep, keep it right here at
