AEV’s DualSport Suspension Systems have taken off-road suspension engineering to the next level. At AEV, suspension development is about more than just adding lift height, articulation, or flashy-looking components. It’s about bringing OE-level suspension engineering to the aftermarket to create a true do-anything “dualsport” suspension – one that is both extremely capable off-road, while offering unparalleled on-road performance and handling.
To achieve this, AEV relied on factory engineering methodology. We started with the JK’s control-arms, track-arms and steering. The geometry of each component was optimized to accommodate the new lifted posture of the JK. It may surprise people to learn that proper geometry is where AEV’s Dualsport Suspensions get much of their tremendous cornering and braking characteristics. The fact is, when the geometry is right, the springs and shocks don’t have to compensate for poor performance in these areas.
Once the geometry was correct, we turned our attention to the springs, again relying on OE methods, which in the case of springs means frequency tuning. Frequency-tuned coil springs share harmonious oscillation characteristics that allow them to work as a matched set, front and rear. The benefit is that they help to keep the JK balanced and in contact with the road, even when driven at high speed over rough surfaces.
After the springs were tuned, the next step is shock tuning. Rather than use an off-the-shelf shock tune, we partner with the engineers at Bilstein to develop a proprietary tune matched to our unique suspension. Together we spent days at a proving grounds facility testing numerous valving combinations in an array of simulated driving conditions. Thanks to the previous optimization of AEV’s geometry and coil springs, it allows us to tune the shocks with a focus on damping suspension movement – rather than on trying to mask unwanted handling problems resulting from poor geometry or spring tuning.
Overall, no matter which Dualsport Suspension System you choose, no matter where you drive it or how you load it, you can count on your Dualsport-equipped JK to remain comfortable, balanced and ready to explore.
Key Features:
- Expedition-Ready / Daily-Driven Practical. More so than any of its predecessors, the JK Wrangler is not just a trail-mastering off-road specialist, it's a truly "street able" on-road transport too. The AEV DualSport enhances the JK to raise its performance in both arenas.
- Tuned Vehicle Dynamics. The DualSport system has been thoroughly tuned for impeccable behavior in every situation you might put it in - and especially the ones you didn't intend to.
- Complete. AEV DualSport JK systems are truly stand-alone packages that include everything needed to elevate your JK properly, including shocks.
Tech Specs
Application: 2007+ JK Wrangler
Made In: United States
Recommended Tire Size:
• 3.5" suspension lift can work with up to 37" tires, but we recommend 35" tires

Notes:
• 2012 Exhaust Clearance: Installation on a 2012 JK requires a minor exhaust system modification to clear the driveshaft, which can be done at your local exhaust shop.
• 2007-2011 Driveshaft: For installation on a 2007-2011 automatic trans JK we recommend a narrower drive shaft
• Diesel Compatibility: To install on a 2011+ Diesel JK with a Diesel Particulate Filter (DPF), you will also need AEV's custom DPF tube.
Variations
LHD vs. RHD: The RHD Kit includes unique High Steer Kit and Track-bar brackets to account for the unique geometry of the RHD vehicle.
2 Door vs. 4 Door: The 2 Door and 4 Door kit each include unique springs to account for the weight and wheelbase differentials between the two vehicles.
3.5” vs. 4.5”: In addition to taller springs, the 4.5” kit also includes shock extension brackets.
FAQ
There are a lot of suspensions available, what sets yours apart from all the others?
The contents of your 3.5-inch and 4.5” DualSport Suspension Systems are very different from the other kits I’ve looked at – why?
What is “Frequency Tuning” and what are its benefits?
The shocks that come with the systems look like ordinary Bilstein 5100’s, are they?
Does the great handling AEV’s DualSport Suspension Systems provide mean that you have stiff springs that don’t flex well?
I do a lot of backcountry adventuring that sees my JK heavily loaded, but I also daily-drive it. Will your suspension sag when loaded or beat me up when empty?
The Premium systems add the High Steer Kit – what does the High Steer Kit do?
Why doesn’t AEV offer a long-arm system for the JK?
Why don’t you supply new/adjustable track bars in with your DualSport Suspension Systems?
Why do you use brake hose drop brackets instead of longer braided stainless hoses?
Do I need to change my drive shafts to use your kit?
What parts are different between a 3.5” and 4.5” DualSport Suspension Systems? Can I upgrade easily?

This past Sunday I finished up my install of an AEV 3.5" lift, AFE y-pipe and 35" Cooper STT tires. I had the JKU aligned on Monday morning and left for TN a couple hours later. I went down to Merryville, TN which is about 30-40 mins away from US 129 (AKA "The Tail of the Dragon). For those of you that have not heard of it, part of US 129 highway is nick named "The Tail of the Dragon" because of its shape/amount of turns. In an 11 mile long stretch of highway there is 318 turns and is a very popular spot for sport bikes/cars. I had been on this roadway in past years in my modded 2000 SVT Lightning. So I thought it would be fun to see how my new toy would perform. I knew that I would never set any speed records with the JKU but i wanted to see how the AEV suspension would handle tons of turns at a above avg speed. I was kinda easy on the JKU due to only having around 300 miles on the new suspension/tires, past knowledge that this road would destroy the brake pads and rotors AND my JKU only had 2k miles on it at the time.
I LOVED how this setup performed! The AEV suspension could have handled way more speed than what I was traveling at. The suspension never once felt unstable, controlled the body roll and only under steered a couple of times when coming in too hot. It rides better than the stock Rubicon setup. Between the dragon and the my week long trip I put almost a 1,000 miles on my JKU/AEV suspension & tires. I did a lot of highway driving (dry and wet) and some gravel roads. The suspension and tires performed amazing and I would recommend this setup to any one! (Posted on 3/27/12) - Better performance on AND off road - Review by Chuck
- Obviously I expected the mods to improve off-road performance and they definitely have however what I’m most impressed with at this point is the unexpected improvement in comfort and performance on-road. I still can’t believe that adding a 3.5” lift and off-road tires has actually improved the overall ride quality on the road. At the risk of sounding crazy I think I would say that even if my Jeep never left the pavement (which it most definitely will be doing on a regular basis) it was worth the cost of the mods for the improvement in on-road ride qualities. Not to mention that it just looks straight up bad ass! I think I stood in the garage for 2 hours Friday night just looking at it. (Posted on 3/21/12)
