Review & Install Video
I'm Ryan from ExtremeTerrain.com, and this is my review of the Mammoth Leveling Kit fitting all 2007 to 2016 JKs. Our JKs come out of the factory with a little bit of a rake. That is to say that the front of the Jeep is slightly lower than the rear. A leveling kit like this is a good way to level out the ride of the Jeep and add a little bit of lift all the way around.
The Mammoth Leveling Kit is really simple, bare bones, and inexpensive. As you can see, it's lift spacers and not springs, there are no shock extensions, sway bar links. It's not an adjustable kit. So if you're looking for something inexpensive and bare bones that you can build on, this is a good way to get started. As you can see, this is a coil spring spacer kit as opposed to a coil spring leveling kit. The coil springs that come in a leveling kit are generally a little bit stiffer than the factory springs, so they can support some additional weight. With this system, you're using the factory springs. So if you have a lot of weight on your Jeep and you wanna stiffer spring, you might wanna take a look at one of those coil spring leveling kits.
As you can see, this leveling kit includes metal coil spring spacers. This sets it apart from some of the other kits on the market that include polyurethane spacers. Now some people will say that the metal spacers are a little bit noisy because you have metal on metal where the spring contacts the spacer. I haven't noticed that in my experience, but it is something to keep in mind.
Another benefit of having a metal spacer over a polyurethane spacer is that they'll generally hold up a little bit better. And, yes, I have seen some polyurethane spacers break down over time, but it usually takes a long time. And let's face it, a leveling kit is just an entry into lift kits, and most people aren't gonna have this installed on their Jeep long enough to have that wear and tear breakdown. Like I said before, this is a really bare bones leveling kit. It comes with the coil spring spacers you see here and nothing else. And that's okay. You can run this kit as it comes right out of the box without any issues. However, if you decide to take your Jeep off-road and you want some additional suspension performance, there are some things you can add.
One of those components would be longer sway bar links upfront, or disconnectable sway bar links. Being able to disconnect the sway bar when you're off-road will provide additional suspension travel and articulation which is always a good thing. Another component you might consider adding when installing this leveling kit would be longer shocks or shock extensions. Any time you change the ride height of the vehicle, you change the down travel of the shock because the shock's only so long. So adding some extensions or longer shocks will provide additional suspension travel.
Another component to consider any time you're changing the suspension or ride height of a vehicle is bump stop or bump stop extensions. You want to fully cycle the suspension to make sure you're not going to fully compress the shock which could cause damage, or have a tire contact the body. Installing a coil spring spacer leveling kit, like this, ends up being a lot of the same work and labor as installing a full lift kit. The first thing you'll need to do is support the vehicle from the frame and disconnect or remove everything that keeps the axles from completely drooping. Once the axles are drooped, you can pull out the springs, install the coil spring spacers, and put everything back together.
This will include removing or disconnecting your brake line brackets, track bars, sway bar links, and shocks, maybe even your drive shaft. Once you get everything installed, you'll want to cycle the suspension and check for clearances. You'll want to make sure that at no point during the suspension travel do the brake lines become completely taut, and you'll wanna make sure that the bump stops are set so that you won't fully compress a shock or fully compress a spring causing coil bind which can damage the springs.
The whole installation should take about two hours, and you won't need any specialty tools, just some sockets and wrenches. And, as with any lift kit, it can be done on the ground with hand tools, but if you have a lift or air tools handy, that'll definitely speed up the process. Any time you're working on an older Jeep or a Jeep with some rusty bolts, it's helpful to have some penetrating oil or some heat on hand for the stubborn ones.
This kit is a good value for the cost. It is one of the less expensive leveling kits on the market, but that makes sense because it doesn't include all of the other components that are in some of those other kits. So if you're looking for a bare bones, inexpensive leveling kit to get you back on the road, this is a good option. However, if you're looking for a kit that includes everything you might add to this lift kit all in one box, that's available on the site as well for an additional cost.
A leveling kit is often one of the first big mods someone will do to their Jeep. So if you're looking to level out that factory rake and have a simple way to add a little bit of height, either just for the look or to run a slightly larger tire, this is the type of product that you should be looking at.
So that's my review of the Mammoth Leveling Kit fitting all 2007s to 2016 JKs that you can find right here at ExtremeTerrain.com.
