Forward Clutch Hub Washers
  • TH400, 4L80-E

    Package Quantity: 5

    Forward Hub , .078" Thick

    • Outer Dia.: 1.781"
    • Inner Dia.: 1.289"
    • Thickness: 0.078"
    • Material: Steel
    Sonnax forward clutch hub washer 34298-078 is .015" thicker than the OE version and replaces the OE .063" thick washer between the forward clutch hub and the forward drum. This allows front unit endplay to be reduced. This new washer is an alternative to the Sonnax washers, 34301-078 and 34301-094. Shimming at this location maintains the relationship with the forward clutch hub and direct drum and does not alter the endplay path through the unit.

    • Forward hub washers are .015 thicker than OE
    • Installation between the forward drum and forward clutch hub reduces front unit endplay
