Air Bags (Air Springs) for Heavy Duty Trucks

Air bags, also known as air springs, are a critical component in modern heavy duty truck suspension systems. Unlike coil or leaf springs, these flexible, rubber-reinforced bags use compressed air to support the truck’s weight, absorb shocks and provide a smoother ride. They also maintain ride height and improve handling as load conditions change making them perfect for trucks that carry variable cargo or operate in harsh conditions.

Heavy Duty Air Bag Suspension for Commercial Trucks

At Custom Truck One Source we offer a range of air bags designed for vocational trucks, trailers and other commercial equipment. Built to last, these air bags improve ride comfort, reduce wear on chassis components and adapt to changing load conditions. With adjustable air pressure air spring systems can be tuned for optimal performance whether your truck is loaded or empty.

Air bags are installed between the truck frame and axle and when pressurized they act like an adjustable spring that absorbs road shocks and supports vehicle stability. This gives better handling, reduced vibration and a smoother ride – all of which equals better driver comfort and reduced fatigue.

Find Your Air Bag

Our inventory includes air springs in various sizes and styles to fit different truck configurations and suspension systems:

• Replacement air bags for heavy duty truck and trailer suspension systems
• Air springs for load-leveling so the truck maintains proper ride height regardless of cargo weight
• Options for factory and aftermarket suspension setups

Each product listing includes dimensions, mounting style and load capacity so you can quickly find the right air bag for your vehicle and suspension needs.
