    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.

    Increased Lift. Increase the ground clearance of your Jeep Wrangler JK by 2 inches in the front and 1 inch in the rear with a Mammoth 4x4 Leveling Kit. This Leveling Kit will allow you to run tires up to 33 inches in size, making it more suitable for both on and off road use.

    Removes Factory Rake. The Mammoth 4x4 Leveling Kit will not only increase ground clearance, but will also raise the front of your JK slightly higher then the rear to eliminate the factory rake, leveling out your Jeep for a more aggressive off-road look.

    No Change In Ride Quality. The Mammoth 4x4 Leveling Kit will not affect the OEM ride quality of your Wrangler, it is just allowing you to run larger diameter tires with no other modifications necessary.

    Mammoth 4x4 Spacers. The included (2) 2" front spacers and (2) 1" rear spacers have been laser cut from heavy duty Mill Certified Steel that has been completed in a durable powder coat finish for long lasting corrosion resistance.

    Application. This Mammoth 4x4 Leveling Kit is specifically designed to fit all 2007-2018 Jeep Wrangler JK models.

    Please Note. If you are using stock wheels, you may need wheel spacers for 34" tires to prevent rubbing. ExtremeTerrain recommends the RedRock 4x4 1.5 inch Wheel Spacers, item number J100792

    Will I need/ or should I install anything else to complete this installation, shocks, sway bar links, brake line relocate, etc. ?

    can these spacers be installed with an existing lift on now? 3.5 on a 2010 JK.

    • Thank you for your question! Yes, you can install the Mammoth Leveling Kit with your 3.5 inch lift kit, as long as it does not already include any coil spacers. It is highly advised against stacking coil spacers.

    Good day, I need to know what the inside diameter of the front spacers are. I tried to install one set from another manufacturer that had inside diameter of 2 1/8" but would not fit my JK. I need some that have a inside diameter of ~2 7/8". Thanks

    • We do not have the exact specs of the inside diameter of the front spacers, but they're a direct fit for 2007-2018 JK Wranglers, both 2-door and 4-door models, both Sports and Rubicons (and of course Saharas). We would be unable to recommend them for use with any other model of Jeep, or other vehicle.

    If this is a leveling kit, why are there spacers for the rear? Would not leveling only require raising the front?

    • The Mammoth Leveling Kit provides a small 1 inch lift as well as the leveling.

    Have a 2013 JK and have purchased a Barricade Trail Force HD bumper from you, not installed yet and plan on purchasing the rear Barricade bumper also. Will this leveling kit be able to support the extra weight of the bumpers?

    • Yes, theMammoth 2 in. Front / 1 in. Rear Leveling Kit will be fine with additional weight from aftermarket bumpers.

      Very cheap paint

      Chipped and peeling paint just from shipping, with rust already starting. Had to install the front spacer under factory rubber isolator, because it is too wide of a diameter to sit flat in the front upper spring perch. Rear was better, though not perfect, but did set that as instructed. So now there is metal to metal contact, thus rust will be an issue in the salt belt states. Ride would probably be better with longer shocks and sway bar end links, but it goes down the road okay. Have not tested off-road yet. Jeep looks level and fits 33"(255/85R17) tires nicely now. Overall a fairly inexpensive spacer kit, though I would use polyurethane next time, as I have before in the past. Recommendation: do not disconnect either track bars, as both axles can be lowered enough to easily install these, even with a spring compressor. Special note: also had to disconnect the front of the front drive/propeller shaft so not to damage the accordion boot for the slip spline on cross-member that is directly below it. And I had to disconnect and modify the parking brake hanger to prevent damage to the cables. It took longer with all this ^ plus I loosened all the control arms to reset the bushings for longer life and a better ride quality, as well as did a tire rotation, etc. Thanks for reading and I hope this helps. Just wish there was better and more complete instructions for those that need them.

      5 Stars for being exactly what it says

      The only thing negative that any reviews mentioned of this kit was being louder due to metal on metal components. I haven't noticed the slightest bit! I have a 2016 JKU Backcountry edition running stock BFG KO2s and this leveling kit gave every bit of what it should. Looked like much more than 2" front and 1" rear. Really improved the stance and feel yet ride remains perfectly stock quality. Gave noticeably more center clearance and will allow for the 33s I'll move to next while still being able to aggressively wheel to the limit. Super simple install, don't cheat to make it faster by attempting to use coil spring compressors...just drop the axle unhook everything and its fast. I'm medium skill and did both front and rear by myself in less than 2 hours. Great kit!

      Definitely looks better when you get 2 inches from the front of the jeep. Hated that nose dive look the stock had. This is just temporarily though. I will be getting a 2.5in lift kit with shocks in a few months. Thank you, Team Extreme Terrain.

      Easy and not so easy

      This kit took me 6 hrs to install with basic hand tools, 2 jack stands and 2 floor jacks. To get a better droop on the rear axle you have to remove the e-brake line bracket under the Jeep above the middle of the axle. The other issue was I had to use a spring compressor on the front driver side because the drive shaft wouldnt let the axle drop low enough to put the spring with the spacer in. Otherwise a fairly decent job. A six pack and a few hours later and the Jeep looks great leveled out with about an inch of lift.

      Good product

      Havent had the spacer lift on for too long now but I must say it makes my jeep look great. Installation is not as hard as it may seem, it took my buddy and I around 3 hours to get everything done. Will be looking into longer shocks to add on later, but for the time ive had driving on paved roads it has held up very well and would recommend to anyone who does minimal offroading and wants a small lift to their vehicle.
