Maintain ride quality, stability, and load control with air springs and leveling valves designed for the Peterbilt 352 and other popular models. These critical suspension components play a key role in keeping your truck balanced, comfortable, and performing at its best?no matter the terrain or payload. Air springs absorb shock and support the weight of your cab and trailer, helping reduce vibration, protect cargo, and improve driver comfort during long hauls. Over time, worn air springs can lead to a rougher ride, uneven tire wear, and added stress on suspension components. Replacing them restores your truck's ability to adapt to shifting loads and road conditions. Leveling valves are equally important?they automatically adjust the air pressure in the suspension system to maintain a consistent ride height. This not only improves steering and handling but also helps prevent damage caused by uneven weight distribution. This lineup includes high-quality replacement air springs, level valves, mounting brackets, and hardware compatible with Peterbilt models like the 352, 378, 379, 385, 386, 387, and 388. Built for durability and easy installation, these components are sourced from top brands and engineered to keep your suspension system working smoothly and reliably. If you're experiencing a bumpy ride, poor handling, or sagging suspension, upgrading your air springs and level valves is a smart move that delivers immediate results?on comfort, safety, and performance.
