Ram changed to Borg Warner cases when they started using the 8 speeds, which changed the stud size from 3/8 to 10mm and the clocking of the T/C was set at 23-26 degrees and Jeep got rid of the 6 bolt pattern completely. This Tail-shaft will now allow you to bolt up all the common 6 bolt T/C that we use and love.


  • One Piece Billet 6061-T6 Aluminium
  • 3 Clocking Positions
    • Flat 3°
    • Jeep 13°
    • Truck 23°
  • 4 tapped holes for custom trans mounts.
  • Fits Both the Hemi and Eco Diesel Trans (They have different mounting hole patterns)

Supported Trans

  • Gen 2 4x4 8HP70 (2014-2018)
    • Ram 3.0L Eco Diesel
    • Ram 5.7 Hemi
    • Jeep Grand Cherokee 3.0 Eco Diesel**
    • Jeep Grand Cherokee 5.7 Hemi
    • Jeep Grand Cherokee 6.4 Hemi

** The Jeep Eco Diesel has a longer output shaft of 0.300" which will cause the T/C to bottom out in the input before you are able to bolt it up.  A custom 0.300" spacer will be needed with longer studs to get this to bolt all up.   We currently do not offer those parts to support this application.

  • D300 (CJ, with a 23 Spline input)
