This adapter assembly is designed to adapt the Cummins R2.8 to a Chevy LS (Gen III & IV) 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 Flywheel
  • Crank Hub Adapter
  • Hardware Kit
  • Dowl Pins


These can be used on any manual or automatic trans found behind the Chevy Gen III & IV LS engines.
