Cummins R2.8 automatic GM:

Finally a real solution to the Cummins R2.8 automatic is here.  Quick Draw Brand has been asked over the past year to make a kit that is easy to install, cost effective, and works.  Besides the Cummins R2.8 Automatic GM style a Ford multi pattern is releasing at the same time.

You will receive the Cummins R2.8 Crate engine; new from Cummins Repower, and a QDB GM auto kit fitting transmissions that came off the small block Chevy engines and the LS.  TH400, TH350, 700R4, 4L80, and 6L80e will bolt to this adapter.  This kit uses a factory Cummins flywheel /flexplate so no worries about welds coming apart.  Designed around installation in short wheelbased vehicles this kit is the shortest on the market and the flexplate bolts are easily accessible.  Compare the price of this engine and adapter kit vs Cummins price on just the engine; you will find that packaging the parts in this kit makes the whole process easier and cheaper.  This is not a complete installation kit but includes the most important parts to get your Cummins Diesel Conversion bolted together.
