Air Spring Rolling Lobe

The AB1DK23P-9923 Air Spring Rolling Lobe from Wofford Truck Parts is a precision-engineered pneumatic suspension part built for heavy-duty applications. Designed with a rolling-lobe architecture, it expands and contracts under pressure to absorb shock loads, maintain chassis height, and reduce vibration transmission. The top and bottom plate mounting surfaces are molded to exacting tolerances, while the composite piston and rugged rubber materials resist fatigue, ozone, and temperature extremes. As a direct-fit replacement for many OE and aftermarket units (such as W01-358-9923, 1R12481, AS9923, KW30325), it offers dependable service in demanding trucking environments, helping protect frame, axle, and cab mount components from stress and wear. Wofford’s distribution includes full support and quality assurance, making this air spring a solid choice for fleets seeking durability and performance.
