Product Description
- Fits Engine Years: 03-25.
- Fits Transmissions: Allison 1000 and 2000 Series.
- The G Force Cummins to Allison Adapter Plate and Flexplate Kit accommodates 2003-2025 Cummins 6BT / Common Rail engine, bolting to a GM Allison transmission, for model years 2001-2025, or with the Duramax bellhousing pattern.
- The G Force adapter positions the transmission straight, not angle rotated as some OEM applications.
- The Allison transmission 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.
