Benefits of Air Suspension

Superior Ride Comfort (Especially When Unladen):

Biggest Advantage: Air springs inherently absorb small bumps and road irregularities better than leaf springs or even coil springs. This greatly improves everyday driving comfort, especially when the truck is unladen or lightly loaded—a common problem with conventional truck suspensions.

Adjustable Damping: Many factory air suspension systems, such as Ram’s, come with adaptive dampers that adjust based on road conditions and driving mode, further improving comfort and handling.

Automatic Load Leveling:

Critical for Towing/Hauling: When you hitch up a heavy trailer or load a cargo box, the system automatically maintains a level ride height. This is critical for:

Safety: Proper headlight aiming, proper steering geometry, and stable handling.

Towing Stability: Prevents trailer sag from destabilizing the truck.

Solid Handling: The truck rides and handles similarly whether loaded or unladen.

Adjustable Ride Height:

Access Mode: Lowers the truck for easier entry, exit, or loading (common on OEM systems like GM and Ram).

Off-Road Mode: Raises the truck for increased ground clearance over obstacles.

Aerodynamic Mode: Some systems automatically lower the truck at highway speeds to slightly improve fuel economy.

Leveling on Uneven Ground: Very useful when camping or loading on a slope.

Enhanced Towing and Hauling:

Air suspension not only keeps the vehicle level, it also provides a more stable, controlled, and comfortable ride when towing a heavy load, whereas conventional suspensions tend to shake or shimmy when overloaded.

Potential Resale Value: Trucks with good factory air suspensions can be more attractive to some buyers.
