Air Bags

When you need reliable suspension air bags (also known as air springs) for heavy trucks, trailers, and vocational equipment, American Radiator is your go-to source. Our selection of suspension air bags is designed to absorb road shock, maintain ride height, and improve stability — critical for handling heavy loads, protecting cargo, and reducing wear on axles and tires.

Each truck air spring / air bag we provide is engineered for durability and performance in demanding applications. Whether it’s for Freightliner, Kenworth, Peterbilt, Volvo, or Western Star, our parts are built to match OEM standards — offering proper lift, travel range, and mounting compatibility. The rubber and reinforced materials resist abrasion, ozone, and high-pressure fatigue, ensuring longevity even in harsh field environments.

Because suspension failures cost downtime, our in-stock air bags are supported by fast fulfillment, technical fitment support, and cross-reference guidance to get you the right part the first time. Pair them with our radiator, coolant, and cooling system components for a full vehicle systems approach.

Trust American Radiator for high-performance air springs / suspension air bags that deliver controlled ride quality, load support, and rugged reliability for fleets, contractors, and owner-operators nationwide.

FAQ'S

What types of air bags do you carry for heavy-duty trucks?
We offer a wide selection, including single-convolution, double-convolution, coil-over, and roll-off style air springs compatible with various truck frames and ride heights.

How do I choose the correct air bag size and travel for my application?
Select based on load capacity, ride height requirements, mounting geometry, and stroke length. Use OEM specifications or consult our cross-reference guides to match the right part for your suspension.

Can I use air bags together with leaf springs?
Yes — many systems use helper air bags to supplement leaf springs for load leveling. They activate when payload increases to maintain stable ride height and handling.

What are common failure modes for air bags?
Typical issues include leaks (from pinhole corrosion or abrasion), ruptured bellows, weak mounting hardware, or misalignment that causes rubbing or stress on the air spring body.

How often should I inspect or service air suspension components?
Inspect during every major service interval (e.g., 10,000–15,000 miles). Check for leaks, mounting cracks, proper ride height, and corrosion or wear on fittings and brackets.
