The phrase refers to aftermarket suspension systems designed for Toyota Tundra trucks that utilize air springs instead of traditional steel springs. These systems replace or supplement the factory suspension components, offering adjustable ride height and improved load-carrying capabilities. A common example includes kits that replace the rear leaf springs with air bags, leveling the vehicle when towing or hauling heavy loads.
The significance of such a system lies in its ability to enhance both the comfort and utility of the vehicle. Benefits include a smoother ride, especially when traversing uneven terrain or carrying substantial weight. Historically, air suspension systems were primarily found in luxury vehicles; their application to trucks like the Tundra represents a desire for increased versatility and performance. The system’s adaptability allows for maintaining optimal ride quality regardless of cargo.
