  • Tabbed and Figure-8 thrust washers feature steel-backed bimetal for improved strength and a PTFE lining for high wear resistance
  • Figure-8 thrust washers have a wider web for increased strength
  • Rear sun gear thrust washer incorporates an enclosed thrust bearing within the thrust washer that eliminates compression and distortion of the standard thrust washer due to input shaft thrust loads
