Heavy-Duty Truck & Trailer Air Springs
A reliable air ride suspension system is essential for your truck. When your air springs (aka air bags) are functioning perfectly, they absorb severe road impacts, protect fragile cargo, reduce chassis fatigue, and deliver a safe, level ride height. At Fast Lane Truck Parts, we carry a massive inventory of OE and aftermarket air springs for all major Class 6-8 truck and trailer applications.
Whether you are running a Freightliner, Kenworth, Peterbilt, Volvo, Mack, or International, we have the heavy-duty components you need to stay on the road. Our catalog features high-quality air springs designed for drive axles, steer axles, heavy-duty trailers, and cab suspensions.
Air Springs for Every Commercial Application
We offer replacement parts that meet or exceed OEM specifications, and designed for the challenges of the roads. Our inventory covers:
- ► Drive & Trailer Axles: Rolling lobe air springs engineered for high load capacities. We cover all major suspension systems, including Hendrickson, Neway, SAF-Holland, Reyco, and proprietary OEM systems such as AirLiner.
- ► Lift Axles & Convoluted Springs: Single, double, and triple-convoluted bellow springs designed for heavy-duty vocational lift axles, offering rapid inflation and superior lifting power.
- ► Cab & Sleeper Suspensions: Don't let frame vibration wear down your drivers. We carry the specific airbags and sleeve styles required to isolate the cab and sleeper from harsh road conditions, improving driver retention and comfort.
How to Identify Your Replacement Air Spring
Air springs come in hundreds of variations involving different top plates, bottom pistons, and mounting stud configurations. The easiest way to find your exact replacement is to look for the OEM or manufacturer part number stamped directly into the rubber bellows or the top plate of your old bag. If the numbers have worn off, our heavy-duty parts specialists are here to help. Contact us with your vehicle's VIN or trailer suspension model, and we will accurately identify the exact part you need.
