Specifications

When servicing a Hendrickson TF II air-ride suspension, the TRB5912 pivot bushing is a foundational component to replace. This heavy-duty bushing is compatible with INTRAAX and AAL/AA series beam suspensions (for example AAL23K, AAL25K, AAL30K, AA230L, AA250L, AA300L) and helps support the beam at its pivot point, reducing unwanted movement and maintaining ride quality. With OEM part numbers such as 46914000, C21824, S21824, C3558 and E3772, this bushing is listed as the preferred replacement.

Wofford Truck Parts supplies this component to restore proper articulation, reduce squeak or clunk at the beam pivot, and extend the life of suspension bushings and hardware. For optimal installation, ensure the bushing bore, outer shell and beam bracket clearances are within spec and lubricate appropriately before final torque.
