    Don't wait for adventure to find you. AccuAir's Dynamic JT Diesel 4" lift kit provides a top-of-the-line performance suspension upgrade with tons of versatility and functionality to take you on every adventure you could ever dream of. Raise and lower your Jeep on demand to meet your needs and have the best ride in the industry!

    Our 4" lift kit easily clears 37" tires on 4.5" back-spaced wheels. You can go practically anywhere.

    You can install this kit in your garage! 100% bolt-on: no cutting, no drilling, or no welding needed to upgrade your Jeep at home. We provide a detailed, easy-to-read installation guide that walks you through every step of the process. Once installed, simply press a button on the hardwired TouchPad controller or Bluetooth-enabled ePlus app and enjoy your new dynamic suspension.

    Need to tow a trailer or haul equipment? This rugged suspension system allows you to easily haul the max Jeep Gladiator JT Mojave tow rating and allows you to automatically level your load. Our kit eliminates the sag that many experience with traditional lift kits.

    Never worry about adding a winch bumper, tire carrier, or rooftop tent. Our Dynamic lift kit automatically compensates for anything you add to the vehicle. Our system is great for everyone. You don't have to lose ground clearance or risk damage to your vehicle by adding low-hanging steps. This kit allows you the flexibility to lower your vehicle for easy entry and exit. When the trail ends, your fun doesn't have to.

    The underbody mounted 5-gallon air tank and compressor provide all the onboard air you need to quickly and efficiently inflate tires, water toys, camping furniture, and more. Press Position 1 on the controller, which lowers the Jeep 1", so your family and pets can easily get in the Jeep. The kit defaults to the standard 4" lift when you're going 25MPH or faster. With this safety feature, choose your preset height to navigate low garages and drive-thrus OR raise your Jeep to navigate offroad obstacles.

    Want to go offroad or rock crawling? Using AccuAir Crawl Control under 25MPH, you can raise your entire Jeep by 2" or lower by 2". You can also raise and lower individual corners to tackle obstacles on the trail. Planning to camp? You can adjust individual corners to create a level platform for sleeping.

    This kit is awesome!

    I installed this kit on my dad's diesel JT and then we drove it cross country and took it to Moab to test it out. Overall it did great, we really put it thru the ringer on some tougher trails (rusty nail). Very happy with the ride quality as its much better than stock. I would recommend this kit if your looking for on and off road capabilities, its the best of both worlds.
