      Video Review & Installation

      Merideth: Hey, guys. So, today we're checking out the Mammoth one and one and a quarter-inch Billet Wheel Spacers in Black, fitting all 2018 and newer JL Wranglers. So, if you are in search of a wider look for your JL, spacers are a great option. And this kit by Mammoth will be a very affordable kit to take a look into. Now, this kit is gonna come with two spacers and will push your wheels out from the hub one and a quarter inch, creating a more aggressive stance compared to your stock stance. Now, this size spacer will be for somebody who isn't looking to go too aggressive with their stance in comparison to a larger option but is looking for that extra width when it comes to the wheels and tires on their JL. Now, this will also be a great kit if you've upgraded to a wider tire and you're having some rubbing issues inside the wheel well or your suspension components, and you're looking for an affordable fix to help your fitment.Now, I would like to mention that this will come with two spaces in the kit. This is the full kit on the table, so what you see is what you get. So, if you are looking to put these on all four corners, you will need to purchase two kits. Now, when it comes to the spacers themselves, these will have a 5x5 bolt pattern and work with either your stock wheels or any aftermarket wheels that you're looking to add or have already installed on your JL. Nonetheless, these will be very durable made of a CNC machine billet aluminum construction with a semi-gloss black finish to protect the aluminum underneath from any corrosion. This will also include 10 lug nuts already. As you can see, they're pre-installed on these spacers here, and this will also include a thread locker in the kit that will make sure that these are going to be tightly secured once they're installed and won't go anywhere.Now, like I mentioned, these will be an incredibly affordable solution and one of your most affordable options for wheel spacers at roughly $75. Now, if you're looking at a set of two, you will be looking at roughly $150, but still when comparing it to others in the category, even for a set of two, you'll be saving a couple of bucks. Now, when taking a look at some other choices on the page, usually, you'll see some different sizes, including one and a half, one and three quarter, and even two inches in size, which would offer a more aggressive look in comparison to this one and a quarter-inch. Now, if you're not necessarily looking for the widest look or you just need one and a quarter-inch to help your fitment and not necessarily a larger size, then these are gonna be right up your alley. You'll also see some different colored options or sets that will come with four in a kit instead of the option here that has two in a kit. Those are gonna be great if you are concerned about the color of your wheel spacers. But if you don't really care about that and you are looking for one of the most affordable choices for a wheel spacer that's one and a quarter-inch, then this is gonna be the kit to choose.Now, as far as install is concerned, this will be 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. Now, the tools that you'll need for this install will include a impact wrench, a breaker bar, and a torque wrench. You'll also need a 19-millimeter socket for these lug nuts. You will also need a 22-millimeter socket for your stock log nuts, or you can use your lug wrench. You're gonna need the provided Loctite and you'll also need a jack to elevate the Jeep to get the wheel and tire removed. Now, speaking of the install, one of our customers here has installed this on their JL and is gonna walk you through that process step by step. So, that wraps up my review. Let's go ahead and get into the install.Man: So, before jacking up the Jeep, I'm gonna break loose the lug nuts on here, which are 22-millimeter. Now I'm gonna jack up the Jeep from the front axle using the front differential. The emergency brake is on and the opposite back wheel is chock. Now, back to completely remove the lug nuts from the OEM wheels. And remove the wheel. Now, before I put the red Loctite on, I am going to test fit this. So, I'm gonna make sure all the original studs stick out beyond the face of the spacer. I wanna make sure that the OEM wheel fits on with adequate clearance. This is the slide Red Loctite. You'll need to cut the end off of the bottle concealed. So, after you get them finger tight in the cross pattern, you're use the torque wrench set at 130 foot-pounds to tighten them to OEM spec using the same standard cross pattern. So, I'm doing this by myself. What I had to do is find a way to activate the brake well enough to be able to hold the caliper and the hub still. So, I've used a short piece of pipe and jammed the seat to hold the pedal down. And now that I have the hub or the spacer torqued on, you can install the wheel again with the 22-millimeter lug nuts. We'll torque these slightly in until we can get it on the ground and apply a full torque to them.Merideth: So, that's gonna wrap up my review and the install of the Mammoth 1.25-inch Billet Wheel Spacers in Black, fitting all 2018 and newer JL Wranglers.
