If you keep breaking or cracking your factory Duramax rear engine cover
than look no further because we have a solution for you. Often times, on high
horsepower applications, the factory cast rear engine cover will crack or break
due to the tremendous amounts of stress that this unit has to handle. We have
developed a billet aluminum unit that is completely CNC machined out of a solid
block of aluminum. This unit is a direct factory replacement unit and requires
no additional modification in order to install.
