06-07 Duramax LBZ

The LBZ replaced the LLY late in the 2006 model year and production continued through 2007. A large bump in output was seen with the introduction of the LBZ. Mechanically, the LBZ is very similar to the 2006 LLY model. The most significant difference between the LLY and LBZ is the computer controls. The LBZ features a much "wilder" tune, giving it a large increase in power horsepower and torque output.
