Ram HD 3" DualSport Suspension - '14-'18 Ram 2500/3500 - By AEV
AEV’s Ram DualSport Suspension Systems focuses 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 mated to 3” cast aluminum coil spring relocation spacers to achieve the additional lift height. This takes 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 AEV 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. Bringing the steering geometry back into factory alignment reduces body roll, bump steer, and roll steer, all major contributors to the loose or sloppy steering and driver fatigue commonly associated with many lift kits. The factory radius arms are repositioned for optimal geometry, moving the axle forward 1”. 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.
2500 vs. 3500
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. New u-bolts and bump stops are also included.
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.
No matter where you drive your truck or how you use it, you can always count on your DualSport Suspension-equipped Ram to remain comfortable, balanced and ready to explore.
