AEV - JLU 4D 2.5" Dualsport RT Suspension
Click Image for Gallery
As a true, expedition-ready suspension system, coil spring and shock tuning was essential to provide the optimal balance of load carrying capacity and ride quality that customers have come to expect from AEV. The 2.5” DualSport RT Suspension System includes a set of our frequency-tuned, triple-rate coil springs to provide 2.5” of additional front and rear ride height. The JL Wrangler is equipped from the factory with a very soft coil spring and a fairly stiff shock package, which is not ideal for expedition travel when heavier cargo loads are introduced. For this reason, we went with progressive rate coil springs designed for additional load handling capability and then paired them with set of AEV-tuned, 46mm Bilstein 5100 series shock absorbers for a slightly firm, sportier feel. The AEV/Bilstein coil spring and shock combination used in this suspension not only increases both up travel and down travel but also provides better articulation as well as improved off-road speed potential and bottoming control.
We then optimized the JL Wrangler’s front and rear suspension geometry throughout the entire range of motion, giving you the sporty, responsive handling characteristics that AEV suspension systems are known for. To optimize the frontend geometry, a pair of AEV’s heavy duty control arm geometry correction brackets are included for an improved ride quality and reduced nose dive under hard braking. A rear track bar tower extension is included to correct the rear roll center while also generating a better turn-in response. Extended length front and rear sway bar end links compensate for the additional lift height, while new front and rear bump stop spacers improve bumper/axle contact under full articulation and jounce. Due to this suspension system’s lower lift height, there is no need to swap out any of the OE track bars, control arms or steering components.

- Bilstein Shocks: Tuned to work best with the DualSport RT lift kit, the Bilstein 5100 series shocks offer a slightly firm response to give you more control even at higher speeds.
- Triple-Rate Coil Springs: Being able to handle load and hard braking better than the factory springs was the focus behind developing the triple-rate coil springs in this lift kit. AEV has achieved this without sacrificing the ride quality for daily drivers or serious off-roading.
- Calibration Tool Included: AEV includes the ProCal SNAP with the lift kit to calibrate when adding bigger tires or changing the axle gear ratio. Installing the ProCal harness allows you to control the calibrator using the in dash touch screen making it very user friendly.
