** Call for Availability **

This adapter assembly is designed to adapt the Cummins R2.8 to a Hemi (Gen 3) automatic transmissions.
With our adapter kits, we discard the factory R2.8 Flywheel to reduce weight and inertial load on the adapter kits. 
Our redesigned flywheel is 15lbs lighter then the R2.8 flywheel and with the addition of the crank hub the whole solution is still a few pounds lighter. 

Kit Includes:

  • Bellhousing Adapter Ring
  • Replacement R.8 Flywheel
  • Crank Hub Adapter
  • Hardware Kit
  • Dowel Pins


These can be used on any  automatic trans found behind the Hemi Gen 3 engines.

      • 8HP70 (Ram 1500)
      • NAG1
      • 545RFE

Customer will need the Hemi Flexplate off the transmission they are mating to this adapter.
