I want to know about the crank spacer on the 6.0.I am thinking about ordering the 6.0 complete engine I just want to make sure I get all the parts before I start so there want be any delays when I put the engine in my truck.

 

The crank spacer is only used to adapt the 6.0 to a factory 4L80E transmission setup.If you are using a 4L65E it's not needed.
