    Don't wait for adventure to find you. AccuAir's Dynamic JL 3.5" 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 3.5" 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 Wrangler JL 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 3-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 3.5" 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 1". 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.

    Follow-up after 800 miles trip

    I installed the total package on my Etorque 2019 Rubicon on 35-inch tires in December 2023. A little hard as the wiring was different with the 48-volt battery but we got it done. I also needed help with calibration, but the service department fixed while I was on the phone. So, a working review - I just got back to Washington from a month in Arizona doing some of the hardest trails we could find. Put over 800 off road miles on the system which included from easy dirt roads to some passes with boulders and ledges. Everything worked great. We did a 27-degree side camber and raised the downhill side and lowered the uphill side to 20 degrees, not sure we would have made that with the camping gear on top so a little top heavy. One pass had us dropping off rocks a lot but only hit the frame a few times. We had to use position three on a breakover a couple times. The only issue came with a hard drop onto the frame would knock the sensors out of calibration and arrows would flash red. To correct we would turn the jeep off then back on and it would reset. Happened three times over the 800 miles and always an easy fix. Oh, one last comment, my wife has mobility issues and lowering it to zero (to bump stops) allowed her to get in and out with ease. We are very happy with the total system and highly recommend it to anyone.

    Kept seeing this product online and wanted it for my 2019 Sahara Unlimited. Wanted the ability for the extra lift and air-ride comfort compared to my now replaced 3" lift, as well as the ability to drop the JEEP down at or slightly below OEM stock, having a wife with limiting disabilities, as well as myself being a 100% disabled Marine Vet, as it allows exit and entry with so much more ease; I may be able to get rid of the side-steps, as now they are more in the way, and removing them will give the look of more height when raised. Along with the lowering ability, although I have not tried it but once, during a 3–4-hour drive returning from my weekly service dog training, I may be able to get slightly better mpg driving at a lower height than my previous 3" allotted. So, overall, pretty happy and impressed.

    Pure Fun

    This is the most comprehensive kit of any type that I have installed. Straight forward instructions. I had some software issues but the team at Accuair went above and beyond to help and get it right. Kudos to the team. I feel like a little kid at Xmas every time I get in adjusting the heights for my ride be it my work commute or kicking it on a trail. I’ll never have a Jeep with out this kit ever.

    Just got my Jeep back from install, and i got to say that I couldn’t be more happier with AccuAir. The customer service and tech support was outstanding to deal with. AccuAir went above and beyond to answer any and all questions that i could possibly dream up. I absolutely love the jl kit. My Jeep drives and handles like it did the day i purchased it. I’ve only had my jeep back a few days now, and have somewhere around 150 or so miles on the kit and the ride is crazy smooth. Looking forward to doing some over landing and putting the kit to the test. Im quit confident it will do amazingly well. Would highly recommend for any jeep enthusiasts. The team at AccuAir are amazing folks. Thanks for a great product and and great customer service.
