Engineered for the Real WorldToday's marketplace offers dozens of solutions for anyone looking to modify their truck's suspension, from mild to wild and everywhere in between. There are suspensions designed for going fast, suspensions with flashy components designed for looking good standing still and even suspensions designed for rock crawling that maximize axle articulation and wheel travel. There is nothing wrong with having lots of options but what about a well-engineered, properly tuned suspension system that is designed for the people who rely on their truck every day in the real world and the people who also don't want to sacrifice payload, ride quality or handling just to fit larger tires?The DualSport RT FormulaAEV's 3-inch DualSport RT Suspension lift kit for the 2019+ Ram 2500/3500 is focused on optimizing geometry and custom shock tuning to deliver the best on and off-road performance. This starts in the front end, where Rams come standard with dozens of different spring rates on HD trucks, depending on powertrain, wheelbase, and more, so offering a generic “gas" or “diesel" spring would have been a huge compromise in ride quality and/or load carrying capacity. AEV retains the factory front coil springs and pair them with 3" cast aluminum coil spring relocation spacers to achieve the additional lift height. This allows AEV to take advantage of the full range of factory spring rates and frequencies while still providing the necessary front end lift.Steering geometry is corrected by way of AEV's High Steer Kit, which includes a custom, no-drill forged drag link, AEV track bar and raised track bar tower. This system provides significant improvements to steering precision and handling by correcting the roll center height of the front suspension and bringing the steering geometry back into factory alignment. This results in reduced body roll and bump steer, which are major contributors to the loose or sloppy steering and driver fatigue commonly associated with many lift kits.For many of the same reasons that we chose to retain the factory front coil springs, 2" rear coil spring spacers are included with Ram 2500 suspension systems to provide the necessary lift height without sacrificing ride quality or load carrying capacity. AEV also includes a set of bump stop spacers, rear track bar relocation bracket, sway bar end links and a new power hop bracket (if applicable). The OE leaf springs are retained and new cast iron blocks are installed to provide 2" of lift in the rear on Ram 3500 trucks. Ram 2500 Air Ride and 3500 Air Assist systems are also available.AEV/Bilstein 5100 series shock absorbers are included with all DualSport Suspension Systems. These shocks feature a custom tune developed jointly by Bilstein and AEV engineers exclusively for AEV's DualSport Suspensions Systems. By utilizing digressive valving, the AEV/Bilstein 5100 shocks offer substantial low-speed dampening. The dampening decreases as vehicle speed increases, providing a great ride quality over a wide variety of terrain.As with all of AEV's expedition-ready suspension systems, the DualSport Suspension for the Ram HD 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.Front Axle Relocation KitThe factory radius arms are repositioned for optimal geometry, moving the axle forward 1.0", which was engineered to use a 37" tire. This provides a more neutral impact response, while also allowing more clearance for larger tires. A billet aluminum front driveshaft spacer is included to accommodate the new front axle positioning. We also offer a 1.6" Axle Forward Kit, which was engineered to use a 40" tire.ProCal SNAPAEV ProCal SNAP is a simple, electronic recalibration module that plugs into your 2019-2024 vehicles OBDII diagnostic port. It utilizes the stereo's audio equalizer to input the numerical values for your new tire size- saving you time and money by not having to make a trip to the dealership for speedometer recalibration. The ProCal SNAP also has the ability to recalibrate TPMS and to accommodate for axle gear ratio changes.Please note that the AEV ProCal SNAP is incompatible with 2025 model year and newer Ram trucks. As a result, we have excluded it from our 2025+ kits. This means that features such as TPMS range adjustment are unavailable for these newer vehicles and customers will need to consult their local dealership for speedometer calibration following tire size modifications.For additional peace of mind, the AEV 2019+ Ram 2500/3500 Suspension lift kit is backed by AEV's Lifetime Warranty!
