Duramax FAQ

Which Duramax do I have?

The engine code is stamped on the block and often on a decal under the hood. LB7 ran 2001 to 2004, LLY 2004.5 to 2005, LBZ 2006 to 2007, LMM 2007.5 to 2010, LML 2011 to 2016, and L5P 2017 on.

Do parts interchange between Duramax generations?

Some suspension and driveline parts do, but fuel system, turbo and tuning parts are specific to each engine generation. Shop by engine and year, or send us your VIN.
