Have you decided to do a Cummins R2.8 conversion and already know what transmission you will be using? Quick Draw Brand has developed a wide selection of R2.8 crate engine  and transmission adapter packages that makes ordering the right parts easy, while also saving you money! With this package you will receive a brand new Cummins R2.8 crate engine AND the Quick Draw Brand (QDB) bell housing adapter kit for the AX15 or NV3550. Both of these transmissions were used extensively in Jeep Wrangler applications, but note that this kit will also work with the 5-speed manual transmission found in the Dodge Dakota. Although this is not a complete installation kit (not engine or transmission mounts are included, for example), it does includes the most important parts to get your project started.

Special Note for Wrangler Conversions: The Quick Draw Adapter kit is actually shorter than the factory configuration and enables the transmission and transfer case to move forward with an R2.8 conversion. This allows for a longer rear driveshaft, perfect for your lifted Jeep!  You can even modify the factory AX15 shifter lever to work with the factory access hole in the transmission tunnel.
