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
- 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.
Please note: The AEV/Bilstein 5100
series shock absorbers included in this kit feature a Bilstein Triple C
zinc plated finish. This finish must be serviced regularly in order to
maintain its luster. Particularly in moist climates, a protective
coating, such as wax or lubricating oil should be applied to prevent
tarnishing. The finish is not covered under warranty.
Actual lift height may vary depending on vehicle weight.
