Air Spring Aftermarket

The AB1DK10A-9911 Air Spring Aftermarket from Wofford Truck Parts is designed for heavy duty truck suspension systems where ride comfort, load leveling, and vibration control are essential. Its rolling-lobe air spring mechanism allows controlled expansion and contraction under load, helping maintain consistent ride height and reducing stress on frame and suspension components. Built with resilient rubber, strong internal reinforcements, and precise mounting surfaces, it ensures longevity and leak resistance in harsh environments. It replaces common OEM and aftermarket units—such as 69914, W26-358-9911, 59823-002, 69782-002L—and provides a direct fit in many Freightliner Airtek front axle and Hendrickson setups. Ideal for truckers demanding reliable suspension performance across varied load and road conditions.
