Specifications

The PAI EE34180 bushing is engineered for use in Eaton single and double reduction differentials, replacing OEM bushings such as Eaton 85991, Mack 2719-85991, and Navistar 461730C1. It is used in forward axle, single-reduction Eaton models (DS 34 / 38 / 340 / 341 / 380 / 381 / 400 / 401 / 402 / 451) and their DT/DP variants. The bushing’s job is to guide and support the differential output shaft, reducing noise, vibration, and wear. Built to OEM tolerances, its material and machining are intended for heavy-duty performance. Wofford Truck Parts stocks the genuine Pai unit; perfect for maintaining differential health and avoiding premature replacement of major components.
