AEV 2.5in DualSport RT Lift Kit
JL Diesel
Features & Product Details
AEV first introduced OE-level suspension engineering to the aftermarket over 10 years ago. Today, we continue that legacy with our 2.5″ DualSport RT Suspension System for the Jeep.
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 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, stamped 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.
The all-new ProCal SNAP is included for quick and easy speedometer recalibration, as well as our JL Jack Base for added safety and stability when changing a 35” and taller tire with the factory scissor jack.
Proudly made in the USA and features AEV’s Lifetime Warranty.

* All maximum tire size recommendations are derived from AEV’s product development process using AEV wheels and BFGoodrich tires. AEV products are designed, developed and tested specifically to work with other AEV products. Mixing aftermarket or factory components with AEV components may cause interference/tire rubbing at full jounce or full lock.

REVIEWS & CUSTOMER MEDIA
We have two Jeeps, one is a 2.0T with eTorque and the other is an EcoDiesel, both have AEV lifts installed (among other things). I think AEV does a great job providing value with better than factory road handling and good enough off road capability. It is apparent they tune their components for the various vehicle configuration. Here is my ONLY beef with the diesel lift - not only did they fail to take into account the longer jounce tube, their tech support kind of dismissed the issue as unimportant. The front jounce tube is longer by 1 3/8" for the diesel, 392, and XR package. I've measured it and the install instructions for the Teraflex lift calls it out. To account for the longer jounce tube in these models, you need to install LESS bump extension otherwise you're going to constantly be hitting your bump stops on pot holes, speed bumps, train tracks, basically every day driving. The bump stop extensions that are included in this package (round things in the very center of the picture) are TOO BIG. I took the springs back out and checked clearance without the extensions. They aren't necessary to clear 35" and probably not even 37"s. You only need to add about 1/2" to prevent over compressing the shocks. I used these TeraFlex ones instead: https://www.northridge4x4.com/part/bump-stops/1959300-teraflex-front-and-rear-bump-stop-strike-pad-kit Also, you'll beat the snot out the geometry correction brackets if you play in the rocks but they're relatively cheap to replace.
