Air Spring Rolling Lobe

The AB1DK20D-9422 Air Spring Rolling Lobe is a precision-engineered component distributed by Wofford Truck Parts, crafted to deliver superior ride stability and load support in heavy truck suspension systems. This rolling-lobe style air spring is designed to flex under pressure changes while maintaining structural integrity and controlling lateral forces. With base plates molded in plastic and a robust rubber-lobe assembly, it is built to resist fatigue, ozone, and temperature extremes. It supports consistent chassis height, reduces vibration transfers, and helps protect structural components from impact. As a replacement for several cross-referenced OEM and aftermarket parts (such as WA01-9422C, MAF9422, CONNECT AB-9422, and W01-358-9422), it offers a direct fit and dependable performance in demanding operational environments. Wofford’s offering ensures quality, backed by standards-compliant materials and precision manufacturing.
