Dodge are the first Original Equipment Manufacturer (OEM) to offer Semi Air Kits as an option fit direct from the factory in both 2015 Ram 3500 single-rear-wheel and Dually models
THE AVAILABLE AUTO-LEVEL REAR AIR SUSPENSION SYSTEM FOR RAM 3500 deploys engineering specific to the weight class and the typically tougher assignments given to these pickups. Here, leaf springs are augmented with air springs mounted on top of the axle, resulting in the air springs and leaf springs working together for load carrying. The technology is utilized in both 2015 Ram 3500 single-rear-wheel and Dually models.
Class-pioneering, the groundbreaking Auto-Level Rear Air Suspension System for Ram Heavy Duty models is a dual-mode operator-activated system specifically engineering for the exceptional GVWRs and GCWRs expected from these relentless workhorses.
In Normal Load-Leveling Mode, the system monitors ride heights on both vehicle sides, constantly adjusting for load shifting or changes in road surfaces; a level load profile and proper headlamp-toroad angle—even while undertaking jaw-dropping hauling—is assured.
Alternate Ride Height Mode lowers the rear suspension by about an inch to maintain an even alignment between the hitch and trailer tongue. This mode ensures a level load and creates a parallel, level relationship between the vehicle and the trailer, ensuring an even “rake” from the front of the pickup through the trailer.
