      Video Review & Installation

      Merideth: Hey, guys. So, today we're checking out the Mammoth 1.25-inch billet wheel spacers, in black, fitting all 2020 and newer JT Gladiators.Now if you're in search of an affordable way to get a wider look for your truck, these wheel spacers from Mammoth will be a great choice to take a look at. Now this will also be a great kit if you've upgraded to a wider tire and you're having a little bit of rubbing issues inside the wheel wells and are looking for an affordable fix to help your fitment.This kit will be one of the smaller choices in the category and come with two spacers in the kit, pushing your wheels out from the hub 1.25-inch. Now, this sized spacer is again going to be someone who is looking for more of a subtle look when it comes to the width or just needs a specific size for better fitment. And I would like to mention that this kit will come with two spacers in the kit, so you will need to purchase two sets if you're looking to add these to all four corners.These will have a 5 by 5-inch bolt pattern and work with either your stock or really any aftermarket wheels with that bolt pattern that you're looking to add or have already installed on your truck. These will also be very well-built, made of a CNC machine-build aluminum construction with a semi-gloss black finish to protect the aluminum underneath from corroding. The kit will also include 10 lug nuts as well as the thread locker to make sure that these are tightly secure once they're installed.Now, this will be an affordable solution for wider fitment and one of your more affordable options in the wheel spacer category at roughly $80. Now, if you're looking at a set of two, you will be looking at roughly double that price at about $160. But still, when comparing this to others in the category, you will be saving a couple of bucks even for a set of two of these. Now, when taking a look at other options on the page, you'll usually see different sizes including 1.5 to 2 inches in size, which would offer more of that aggressive or very wide look compared to these. You'll also see different colored spacers on the page, but if you don't necessarily care about a specific color, you're just looking for an easy solution and one of the most affordable ways to do it, then this is going to be for you.So, install's gonna be pretty easy at a one out of three wrenches on the difficulty meter, taking you about an hour to get the job done. Now, at this point, we can head over to the shop and check out a detailed breakdown of the install and what that looks like step by step. So, that's gonna wrap it up for me. Let's go ahead and get into it.Man: Tools required for this install include; a pry bar, a torque wrench, a 19-millimeter socket, red thread locker, an impact gun, as well as jacks and jack stands.What's up, guys? Today we're gonna be installing a set of wheel spacers on our Gladiator, so the first thing we need to do is get our car jacked up. So, let's get started. Now, to install our wheel spacer, it's pretty simple. We're just gonna slide this over the hub. Now you wanna make sure you got a nice flat surface, so if you have any rust on here preventing you from getting that flat surface, make sure you take a wire brush to clean that off first. And then once that's all done, we can just slide our spacer over, and then we can start to install our lug nuts.Now, it is recommended to use red thread locker on our lug nuts that go onto our factory studs. This is gonna prevent our lug nuts loosening up because of vibrations coming from the suspension. For demonstration purposes, we're not gonna be installing the thread locker onto our studs, but you at home, will just put a little dab on there, you don't need a ton, and then thread our lug nuts on. Now the lug nuts that are on our wheel spacer studs are going to be used on our factory studs, so we can twist these off and thread them onto our factory studs.Now, next up, you're gonna want to torque all of the lug nuts to your factory spec, which for our truck is 150 foot-pounds. Now if you didn't have your e-brake set or if you were working on the front, to prevent the wheel from spinning while you're torquing down your lug nuts, you can put a pry bar between the studs like this to hold it into place. So, once we have our torque wrench set to 150 foot-pounds, we can tighten down our studs using a star pattern.And then once you're done torquing your lug nuts down, you can throw your factory wheels back on, torque your lug nuts down to the factory spec, and repeat the same process for our other three wheels. So, that'll wrap up this review and install of the Mammoth 1.25-inch billet wheel spacers in black for your 2020 and newer Jeep Gladiator JT.Thank you for watching and for all things Gladiator, keep it right here at
