How an Airbag Suspension Works

A truck's stock suspension is designed to provide a compromise between ride comfort and the ability to safely haul or tow a payload. If your truck does a lot of towing or hauling, you may find that the rear suspension can sag, which is detrimental to your truck's handling. A similar problem can occur on the front of trucks that are used to plow snow. The best way to overcome this issue and improve your truck's ability to handle extra weight is by installing a set of air springs, the key component of air bag suspension.

How It Works

Air springs install either between your truck's leaf springs and frame or inside its coil springs. Working in conjunction with an air compressor, or manually inflated, and they provide additional support at the front or rear of your vehicle allowing you to maintain a level ride height when hauling a heavy payload. These air springs are adjustable, giving you the ability to inflate and deflate the bags manually or via remote control. You can even adjust the bags individually, which improves handling when you're carrying a heavy, uneven load. This degree of control allows you to create the perfect balance of load support and ride comfort with no compromises.

Most trucks on the road today use leaf springs, a set of curved metal bars stacked together, as the basis of the rear suspension system. When a very heavy load is being towed or carried in the bed, the distance between the frame and leaf springs begins to close, which can lead to bottoming out if the truck hits any bumps or potholes. An air spring bridges this gap and helps shore up the suspension, greatly reducing the chance of bottoming out and vastly improving your truck's handling and braking when under a load.

Coil springs, most often found on the front of modern trucks and SUVs, can begin to sag if the vehicle is overloaded with equipment such as a heavy snow plow. Coil spring air bags help prevent this issue by installing within the spring itself. Once the bag is installed, it can be inflated to maintain a level ride and improve your vehicle's handling and safety.

Recommendations

The AMP-Air by Pacbrake Air Spring Kit will provide capability and comfort on your Ford, Dodge & GM Truck. When you haul heavy loads or pull a trailer, the rear springs can be pushed to the limit–resulting in excessive bounce, sagging ride height, and an overall feeling of instability. It doesn’t have to be this way. With the simple addition of a Pacbrake air suspension kit, you can inflate the air springs enough to support the load without overtaxing the suspension, resulting in a level stance, comfortable ride and confident handling.

Pacbrake has been in the business of building heavy-duty products for OEMs and the aftermarket for 50 years now, so introducing “just another air suspension” simply wouldn’t do. The air springs in Pacbrake air suspension systems are made from double convoluted two-ply rubber, and are the only air bags on the market with one-inch aluminum end caps and 18 support wires for maximum strength and durability.
