The pneumatic system integrated within heavy-duty trucks like the Ram 5500 provides enhanced ride quality and load-leveling capabilities. This system replaces traditional leaf springs with air-filled bags, allowing the vehicle’s height and suspension stiffness to be adjusted based on load and terrain. For instance, when hauling a heavy trailer, the system automatically inflates to maintain a level ride height and optimal handling.
This technology offers several advantages, including improved comfort, stability, and payload management. By automatically adjusting to varying loads, it reduces strain on the vehicle’s chassis and suspension components, potentially extending their lifespan. Its origins trace back to applications in buses and semi-trucks, where ride comfort and load stability were paramount. The integration into vehicles like the Ram 5500 represents an advancement, providing these benefits to a broader range of commercial and recreational users.
