AEV first introduced OE-level suspension engineering to the aftermarket over 10 years ago. Today, we continue that legacy with our JL 2.5" DualSport RT Suspension Kit for the Jeep Wrangler. 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 AEV JL 2.5" DualSport RT Suspension Kit 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 relatively 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 (available in standard load or high capacity) 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. As with all of AEV's expedition-ready suspension systems, the DualSport Suspension for the Jeep Wrangler JL is FMVSS No. 126 Compliant. FMVSS No. 126 is a rigorous standard set by the National Highway Traffic Safety Administration (NHTSA) that tests new electronic stability control (ESC) systems by subjecting it to various maneuvers designed to evaluate its effectiveness in preventing loss of control and skidding, including evasive lane-changing maneuvers at highways speeds. Customers can now fine-tune their Jeep Wrangler JL Lift Kit even further by choosing one of two available coil spring options: 2.5" Standard Load Coil Springs are optimized for an AEV-spec Wrangler with typical gear/cargo inside. This means the ideal ride height, handling and overall performance will be achieved on a vehicle with steel bumpers, winch, full-size spare and recovery gear (+0-400 lbs. over factory weight). With the Jeep Wrangler Lift Kit installed, the JL Wrangler's front and rear suspension geometry is optimized throughout the entire range of motion, giving you the sporty, responsive handling characteristics that AEV suspension systems are known for and 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.
