PRODUCT DESCRIPTION

  • Fits Engine Years: 89-02.
  • Fits Transmissions: Allison 1000 and 2000 Series.
  • The G Force Cummins to Allison Adapter Plate and Flexplate Kit accommodates 1989-2002 Cummins 6BT engine, bolting to a GM Allison transmission, for model years 2001-2024, or with the Duramax bellhousing pattern.
  • The G Force adapters position the transmission straight, not angle rotated as some OEM applications.
  • This adapter kit requires the use of a Ford 6.4L Powerstroke starter.
  • As an option, a Ford 6.0L Powerstroke starter can be used, but some bellhousings will require additional interior clearance.
  • In some applications clearance modifications to the engine block pan rail and the Powerstroke starter may be necessary.
